Has your Braun Oral-B electric toothbrush stopped working?

Is it not behaving as you would expect?

Perhaps it is making more noise than normal.

Maybe it is not charging.

This article offers answers to the more commonly experienced issues with Oral-B electric toothbrushes.

All being well you will find the answer you need to resolve the issue.

If consulting this page or the user manual for your product does not resolve the issue, or you determine the brush requires repair or replacement, contact Oral-B on 1-800-566-7252.

Most products come with a 2 year warranty from Oral-B. Providing the fault falls under warranty terms, this should be resolved for you. In most cases this will be a free of charge repair or replacement.

Products outside of the warranty period will not be eligible for repair or replacement by Oral-B, but their customer support team may still be able to provide some assistance depending on the fault.

My brush head is stuck/won’t come off the handle

  • Run the top of the handle under warm water for a minute or so, to loosen the brush head. Make another attempt to remove it, it should come off with ease.
  • It is recommended to remove and rinse the brush head after each use before placing it back on the handle.

Oral-B toothbrush won’t stop blinking/flashing

  • Green or white blinking/flashing light.
    • The battery is in the process of charging.
    • The light will turn a solid green or go out when complete.
  • Red blinking/flashing light.
    • The battery power is very low and requires charging.

Toothbrush has stopped working the first time I used it

  • The battery of the brush only comes charged to last a few minutes. To maximize the capacity and life of the rechargeable batteries, the power handle should be placed on the charging stand for several hours before the first use.

Handle not turning on/does not work at all

  • The power button is stuck.
    • Toothpaste residue can build-up around the power button. This can cause the button to get stuck and not function correctly.
    • Rinse the handle under warm water for about 10 seconds.
    • Clean the power button and surrounding area with a damp cloth to ensure it is clean and free of debris.
  • Correct button used?
    • If the handle has 2 buttons, ensure the correct button is being pushed.
    • The mode button will not turn the toothbrush on, only the power button.
  • Is the toothbrush charged?
    • If the battery icon indicates that the battery is flat or low on power, it may require charging before it will turn on.
  • Any noise coming from the handle?
    • Turn on the toothbrush with a brush head attached and place the handle near your ear. If you hear a soft humming sound, it is likely that a fault has occurred that will require you to contact Oral-B for warranty support
  • Is the metal shaft in place?
    • With the brush head removed check if the metal shaft that extends from inside the handle. Is it loose or does it come out of the handle? If it does contact Oral-B for warranty support.
  • Has it been dropped?
    • If a toothbrush has been dropped or taken a very hard knock, it is possible that the battery connection inside the handle has been damaged.
    • The connection is usually a small solder connection between the +/- terminals of the battery that connects this to the main printed circuit board.
    • Cracked solder joints can, in theory, be repaired. However, the Oral-B handles are not designed to be opened up by users. Doing so will invalidate your warranty and may even render the brush broken for good.
  • Has it gotten wet?
    • Whilst the brush is designed to resist water prolonged exposure or submersion in water may lead to water ingress inside the handle.
    • Any physical damage to the handle will likely increase the likelihood of any water having impacted the internal electronics.
    • Water can cause corrosion, staining and crystal formation on the circuit board rendering the brush no longer functional.
Oral-B Troubleshooting & Common Issues 1

Oral-B toothbrush does not charge

  • Handle is not fully charged
    • After a total discharge it is possible for the charge indicator to take up to 15 minutes to begin flashing.
    • If you see the battery indicator light blinking it means it is charging.
    • Fully charge the Oral-B handle for up to 22 hours.
  • Not using the original charger
    • Make sure that you use the original charger that came with your Oral-B toothbrush.
  • The socket is not working
    • Try another appliance in the same power outlet/socket and see if that works. If that is also not working the issue might be with that socket. Try an alternative outlet.
  • Has it been dropped?
    • If a toothbrush has been dropped or taken a very hard knock, it is possible that the battery connection inside the handle has been damaged.
    • The connection is usually a small solder connection between the +/- terminals of the battery that connects this to the main printed circuit board.
    • Cracked solder joints can, in theory, be repaired. However, the Oral-B handles are not designed to be opened up by users. Doing so will invalidate your warranty and may even render the brush broken for good.
  • Has it gotten wet?
    • Whilst the brush is designed to resist water prolonged exposure or submersion in water may lead to water ingress inside the handle.
    • Any physical damage to the handle will likely increase the likelihood of any water having impacted the internal electronics.
    • Water can cause corrosion, staining and crystal formation on the circuit board rendering the brush no longer functional.

My Oral-B toothbrush charger isn’t working

  • Any lights on the handle?
    • When a brush handle is placed on the charging stand do any lights flash/blink?
    • If yes, this would suggest the charging stand is functioning correctly.
    • If no, leave the handle on the charger for at least 1 hour and see if the lights are now flashing/blinking.
    • After a total discharge it is possible for the charge indicator to take up to 15 minutes to begin flashing.
  • Handle warmth
    • Is the base of the handle slightly warm after having been sat on the charging stand for a few hours. If so, this is usually a sign it is functioning correctly.
  • Power outlet/socket
    • Try another appliance in the same power outlet/socket and see if that works. If that is also not working the issue might be with that socket. Try an alternative outlet.
  • Cables & damage
    • Check the power lead cable to see if there are any cuts or damage. If so stop using for your own safety.
    • Has the charger recently gotten wet or been damaged in some way? If so, stop using for your own safety.
  • Try an alternative charger
    • Does a friend or family member have an Oral-B toothbrush. If so use their charger to confirm if your brush charges on theirs.
    • If so, it will likely confirm your charger is at fault.
Oral-B Troubleshooting & Common Issues 2

What do the battery status lights mean?

Your Oral-B toothbrush has smart ways of telling you when it is time for a recharge. The lights and beeps of your toothbrush indicate the charging behaviour.  

Some toothbrushes have only one indicator light, while others have three. Below, you can find what the indicator lights mean for each of these models. 

  • Toothbrushes with 1 indicator light
    • Toothbrush on charger
      • No lights – Fully charged and on sleep mode
      • Green or white light flashing – Charging
      • Solid green light – Fully charged
    • Toothbrush not on charger
      • Solid green light – Fully charged
      • Flashing red light – Battery empty
  • Toothbrushes with 3 indicator lights
    • Toothbrush on charger
      • No lights – Fully charged and on sleep mode
      • 1, 2 or 3 lights flashing – Charging
      • 3 solid white/green lights – Fully charged
    • Toothbrush not on the charger
      • 3 solid white/green lights – Fully charged
      • 2 solid white/green lights – Moderately charged
      • 1 solid white/green light – Low battery
      • 1 flashing red light – Battery empty

Note that some toothbrushes like the Vitality series do not have a battery light indicator. In this case, just follow the normal charging advice as specified in the user manual. 

Toothbrush takes a long time to charge

  • Depending on the model of toothbrush it can take anything up to 22 hours to charge an Oral-B toothbrush battery.
  • Most models are fully charged within 12-15 hours.
  • If you are charging your toothbrush on a metal surface, this can cause the charge time to be longer.
  • The tooth brush charger works by electromagnetic induction.
  • Using the inductive tooth brush charger on a metal surface influences the electric flux and reduces the induced power of about 15-20% compared to a non-metal surface. This leads to an increased charging time.

The handle is very loud/noisy

  • Are you familiar with an Oral-B toothbrush?
    • The sound and vibration may appear odd because you are not familiar with the sound that it makes, particularly if this is your first electric toothbrush.
    • Oral-B toothbrushes are louder than Sonicare and other sonic toothbrushes, producing a more mechanical sound.
  • Check that the brush head is attached correctly.
    • A loose brush head may result in increased noise being generated.
    • If no brush head is attached it will likely sound louder.
  • If certain modes the toothbrush will sound louder, and if the highest level of brushing intensity has been set, this will increase the pitch of the sound.

Ticking sound coming from my Oral-B toothbrush

  • On some toothbrush handles you might hear a low ticking sound coming from inside the body. The sound may be heard even if the body is not on the charging station. The sound comes from the working frequency of the voltage converter and can be heard in very quiet environments.
  • This ticking sound doesn’t necessarily indicate any malfunction of the brush.

Toothbrush stutters regularly/pauses briefly

  • This is part of the professional timer, also known as the pacer/quadpacer/30 second timer.
  • A short, stuttering noise reminds you at 30 second intervals to clean all four areas of your jaw (upper right, upper left, lower right and lower left) for the same amount of time (30 seconds).
  • A long spluttering noise tells you that you have reached the end of the two-minute cleaning time recommended by dentists.

Oral-B toothbrush power cycles on/off

  • If the Oral-B toothbrush is turning itself on and off very quickly, and then continues to run this likely normal. This is the professional timer, also known as the pacer/quadpacer/30 second timer.
  • A short, stuttering noise reminds you at 30 second intervals to clean all four areas of your jaw (upper right, upper left, lower right and lower left) for the same amount of time (30 seconds).
  • A long spluttering noise tells you that you have reached the end of the two-minute cleaning time recommended by dentists.
  • If an Oral-B toothbrush is turning itself on or off regularly without input from yourself and not during a typical brushing cycle, the brush requires inspection by Oral-B.

Oral-B toothbrush handle turns itself on

  • If the toothbrush is turning itself on, without any interaction from you, then there is a fault with the handle that requires repair. Contact Oral-B.

Oral-B electric toothbrush head has stopped moving

  • If the brush head is not moving, and the toothbrush is definitely switched on (because you can hear it), try removing and replacing the brush head. It may not be seated correctly.
  • If this does not resolve the issue, use another replacement brush head. This rules out that the brush head itself is the issue.
  • Next, have a look at the metal shaft under the brush head. When the toothbrush is switched on, does it move? It should spin around in a circle. If it does not, there may be something wrong with the handle and it will require service from Oral-B.
Oral-B Troubleshooting & Common Issues 3

Pressure sensor light not working

  • Not all brushes have pressure sensors. Those that do have a red panel on the neck of the brush head or a clear ring around the top of the head that will light up.
  • To function, a certain amount of pressure must be applied.
  • A method to test it:
    • Attach the brush head to the handle.
    • Turn the toothbrush on.
    • With the toothbrush out of the mouth, use your hand/fingers to push on the long neck of the brush head, starting gently, gradually increasing the force.
    • With a light-medium pressure, you should hear the sound of the motor in the handle slowing/straining a little and the light should come on.
    • If the light does not come on, apply a little more pressure, not too much as it does not require lots of pressure.
    • If the light still does not come on, contact Oral-B for a repair.

Water dripping from Oral-B handle

  • Water can build up within or be retained within the brush head attached to the handle. This can exit the brush head over time. This is normally very safe and will cause no issue. It is advised to remove and rinse the brush head after each use. To help it dry, keep it detached from the handle.
  • If water appears to be dripping from inside the handle, look for any signs of possible damage. Consider whether this has happened before and whether this could be moisture that has collected/built-up on the handle.
  • Should you have any doubts bout the safety of your device or you suspect that it is faulty, please do not continue to use it.

Oral-B toothbrush gets warm

  • A rise in temperature during charging is normal.
  • An increase of 40°C above the ambient temperature of the device is acceptable.
  • If the device, the power cable or the power adaptor are damaged or if you have any doubts about the safety of your device or you suspect that it is faulty, please do not continue to use it.

Toothbrush get very hot and parts are melting

  • Please do not use the device.
  • If the device, the power cable or the power adaptor are damaged or if you have any doubts about the safety of your device or you suspect that it is faulty, please do not continue to use it and detach it from the power outlet.

Burning smell/smoke coming from toothbrush

  • Please do not use the device.
  • If the device, the power cable or the power adaptor are damaged or if you have any doubts about the safety of your device or you suspect that it is faulty, please do not continue to use it and detach it from the power outlet.

Oral-B toothbrush smells

  • If it is producing a burning smell, please do not use the device.
  • It is however more likely that the smell is related to residual moisture.
  • It is important to keep the toothbrush clean and allow the toothbrush to air dry.
  • If the toothbrush is unclean or is in a wet environment, damp and mold can form.
  • Store the toothbrush in a dry place with a good airflow and see if it improves.
  • This guide to cleaning a toothbrush may help.

Foreign (grey) susbtance on/in toothbrush

  • The use of rough / abrasive toothpaste can cause abrasion of the metallic parts inside the brush head.
  • Clean the affected brush head thoroughly under running water for a couple of seconds. Turn the device off and detach the brush head. Clean both parts separately under running water and wipe them dry. Let them dry separately.

Rust on metal shaft/metal axis

  • In rare cases it might happen that the drive axis (the metal shaft that the brush head fits to) gets rusty or discolured.
  • This might be more apparent if you store your refill brush head permanently on the handle or if you use tap water filtered from sea water with a high residue of sodium chloride.
  • Try to keep the brush as clean as possible. After brushing, rinse the brush head for several seconds under running water with the handle switched on.
  • Switch off the handle and remove the brush head. Rinse both parts separately under running water then wipe them dry before reassembling the toothbrush.

Oral-B toothbrush handle is discoloring/changing color

  • The Oral-B handles are designed to last and as best as possible resist discoloration.
  • In some instances, the plastics and rubber materials can dull/change color if the handle is not regularly cleaned and dried.
  • If the handle is left in very warm conditions and in direct sunlight.
  • If the handle is used with tap water filtered from sea water with a high residue of sodium chloride.
Oral-B Troubleshooting & Common Issues 4

The metal shaft/adaptor on my handle is loose

  • Remove the brush head and see if the metal shaft on the handle is loose.
    • If yes, there is a fault with your handle. Contact Oral-B.
    • If not, check other troubleshooting advice.

Toothbrush does not vibrate as much as it did/weak vibration/has lost power

  • Make sure that your toothbrush is fully charged – give it up to 22 hours.
  • If your toothbrush has more than one mode of operation, you may have activated a different mode with a different brushing action or intensity.
    • Press the power/cleaning mode button to make relevant changes.
  • Old worn brush heads can also seem to be less effective or powerful in their rushing action.  
    • If your brush head has been in use for more than 3 months, it should be replaced with a new one.

The vibration is too powerful

  • Change the cleaning mode.
    • If your toothbrush has the option to, you may wish to change the cleaning mode selected. Different brushing modes use varying amounts of power from the brush motor causing more or less intense vibrations at the brush head.

Cleaning modes no longer available

  • You more than likely have a particular ‘journey’ set within the smartphone application.
  • If you have a smart (Bluetooth enabled) toothbrush, that has been paired to the smartphone, within the app you can set specific goals/journeys that change the brush configuration, including disabling certain cleaning modes.
  • Enter the app and modify or cancel the journey to restore particular cleaning modes.

Order of cleaning modes have changed

  • You more than likely have altered the order of the cleaning modes available on the brush from within the smartphone application.
  • If you have a smart (Bluetooth enabled) toothbrush, that has been paired to the smartphone, within the app you can change the order of the modes to suit you.
  • The default order might be Daily Clean>Gum Care>Sensitive>Whitening, but you could change this to Whitening>Daily Clean>Sensitive>GumCare.
  • Enter the app and modify the order of the modes within the settings.

Can I turn off Bluetooth?

Bluetooth can be deactivated on models that have both a power and cleaning mode button.

  • Press the on/off button and the mode button simultaneously for 3 seconds to disable Bluetooth completely.
  • Turn the toothbrush handle back on, you should now notice that the Bluetooth icon just above the power bar is now turned off, meaning your Bluetooth is deactivated.
  • You can reactive the Bluetooth anytime, by following the same steps and you will know it is back on when the icon is lit up.

With the Oral-B iO Series Bluetooth can be turned off via the settings on the display rather than via button presses.

      If so, press the button under the screen (the one with the white dot), multiple times until you get to the settings icon which looks like a little like a cog with 8 spokes, press the power button, press the other button twice, then press the power button, press the lower button again multiple times to cycle through the language options. When you see English, press the power button.

  3. Brush head will not stay on. Instead of clicking in place, the head easily pulls off.

    I’ve cleaned the mounting area thinking it might have some deposits, but no luck.

    • Hi Gary. Are the heads you are fitting to the handle, original Oral-B brush heads or are they aftermarket heads made by a different company?

      If they are/you believe they are original Oral-B heads, did you buy them from a reputable source like a larger retailer as opposed to purchasing via an online marketplace such as ebay?

      Reply
      • Thanks, Jon.

        The brush heads are original Oral B replacement heads, at least that’s what the package says. The first three in the package worked just fine. Then, after a month of use, one head just pulled off and wouldn’t re-connect. I got out a new head, and tried it; but it would not “click” on.

        Reply
        • Thanks for this Garry. It sounds a little odd. I am presuming you see no obvious signs of damage to the metal shaft that extends from the handle. And none on the body of the brush handle around the metal shaft?
          Perhaps source some new heads and see what happens. If they don’t fit either, it is likely a case of contacting Oral-B.

    • Hi Emily. It might be worth trying to connect it to the app to see if this changes things. You can reset the brush from within the app.
      I don’t think it will work, but try pressing and holding the power button for 10 seconds, to see if that does anything.

  5. The green charge light on my OralB Pro 1000 is flashing very rapidly while on the charger, mush faster than during a normal charge. If I remove it from the charger and try to turn it on, I acts as though the battery is totally discharged? Can you help?

    It is about 21 months old.

    Reply
    • Does it ever stop flashing or get to the point that it is fully charged? For example, after being on the charger for 24 hours?

      It sounds like something isn’t right and it might need a repair under warranty.

  6. My oral b is pretty quiet sometime but lately it makes a loud rattling noise that starts and stops during the cycle. It is not due to the timer as it happens when first turned on. I have tried removing and replacing the head and even changing heads but this continues. This did not happen when the toothbrush was new.

  7. I have used my oral B genius for 4 months. Now when I use it then it spins for say 10 seconds and stops. Then when I try to turn it off and on it might try to spin but then stops. Like the motor is weak or something is stopping it. I could change the modes but does the same on all modes. No cracks on the handsets. Any advise is appreciated. I can’t return it since I don’t have the receipt anyone.

  8. I have had this issue with two different electric toothbrushes in a row from Oral-B. I get white stuff (presumably toothpaste) oozing out of the BASE of the toothbrush whenever turning on the toothbrush and allowing the metal piece to vibrate (it oozes out through the metal piece when turned on them off, as in, it oozes out every time it gets turned off). I spend hours trying to cycle it on and off to get it all out, along with washing it with water, but more just keeps coming out. What is wrong with my toothbrush, is this normal, and is it safe? It makes the toothbrush often sound like it is gurgling.

      Presumably, it did charge and now it has stopped charging?

      It could be a faulty charging stand or something wrong with the toothbrush. It is likely within its warranty period still, if it is only 1 year old. Contact Oral-B for assistance.

  12. Bought an Oral-B Pro 1000 Power Rechargeable Electric Toothbrush Powered by Braun in June 2021. After charging for more than 24 hours I used the brush and after 2 min the brush turned off and wouldn’t turn on again. I could hear a soft hum when I tried to press the on button but no action occurred. I contacted the seller and am receiving a replacement but I’m concerned this will happen again and that this problem is due to manufacturing/design rather than a fluke problem. Wondering if I should go back to a Philips Sonicare. Bought Oral -B after reading a NY Times review.

  14. My electric toothbrush turned on by itself and wouldn’t stop for 30 minutes. No matter how hard I had tried to pressed the power button it just kept going. In my frustration, I decided to let it ran until it ran out of power. In the meanwhile I googled and hope to find some help. I was so glad that I found your website and read on. It did work when I took the suggestion of letting the power button ran under the warm water for 10 seconds. The trouble shooting has resolved the problem of the electric toothbrush. And now I can sleep. Thank you very much!

  16. Hi,

    So I just bought my Oral B Genius 8000 and have used it for a day or two now. I keep it on the main charging station. I haven’t used the charging travel case yet, but when I plug it in, no light turns on and it’s not charging my brush at all.
    Do you think this could simply be because the case has not been fully charged yet so that’s why a blinking light won’t show up? Or do you think it’s broken?
    Thank you!

    • Slightly odd Olivia.

      My recommendation would be to keep using it until it is completely flat. Then charge it. This might recalibrate the battery and cause the charging lights to kick in.

      Reply
      • Thank you so much for your help.
        So you think I should run the battery out of the brush to then get the travel charger to work?
        It’s such a odd thing. Everything is working as it should except for the travel charger… I plug it in and nothing happens.
        I’ve seen videos of people trying it out, and they make it seem like all I should have to do is plug the charger case into the wall and then the light on the case should just turn on.
        But my case does nothing when it gets plugged in…
        Thanks again- really appreciate your help and knowledge.

        • Hi Olivia.

          I feel it is worth a try. It could also be that the toothbrush is already fully charged from being on the charging stand, so it isn’t ready to be charged in the case.
          You could always ask Oral-B directly for their opinion. It is possible the charger/case is faulty.

  17. My son got braces (and this new Oral B smart electric toothbrush) 11 days ago. The past few days it has stopped registering that he is brushing a certain area (front top) of his teeth. I have watched him brush and he is clearly in the right area, but it won’t detect that he’s there. Any ideas on what could be going on?

      The most common approach here is to reset the brush handle from within the app.
      This usually solves this issue.
      I don’t know the exact reason behind why this happens. But something to do with the configuration of the app/sensors incorrectly reporting/tracking data.

      What brush do you have? Is it still within warranty? Has it sustained any damage or any reason why it might be behaving this way?

      Sounds like it could be a faulty power button.

  18. Oral B Braun toothbrush–Recently the brush head will not stay on the shaft. I started using a new one and it stayed on the 1st 2 times i brushed, then started coming off again.

    • Hi Doris.

      Are you using the official Oral-B brush heads or are you using some made by a different company?

      Has the toothbrush been dropped or damaged in any way that you know of?

      • we’ve been using generic heads, but they’ve worked for the past nearly 3 yrs. it’s just lately that they won’t stay on. And no, it hasn’t been dropped or damaged.

        • Hi Doris. I don’t know for sure, but I would imagine the reason they are coming off is because they have not been manufactured correctly. The hole in the shaft is too large and the vibrations are causing them to come loose.

  19. Toothbrush never stops flashing green. Toothbrush works, but doesn’t matter how long it’s on the charger, flashing green never ends.

      • Toothbrush was new. I put it on the charger for a whole day and blinking light never stopped. Toothbrush works though. blinking light flashes continuously. I’ll try your suggestion though.

  21. Hi,what is the lifespan of a braun toothbrush. mine stopped working now after 5 years…it started by the toothbrush automatically switched on and off. then it died even after charging. is the battery replaceable? i am not sure how to open it up. please advice

    Reply
    • I would say the average life span is around 5 years. Some last longer, some don’t last quite as long, but 5 years is around the typical amount of time.
      The brushes are not designed to generally be repaired or have the batteries replaced. Technically it is possible if you know what to do, but it is easy for things to go wrong. I can’t advise on specific repaired procedures. I suspect financially it would make more sense to buy a new one, despite the appeal of reparing.

  22. oral b, braun, battery-operated toothbrush will not turn off after battery replacement. pushing button only increases or decreases rate of motion.

    • Hi Brenda.

      I have not come across this issue as yet.

      Oral-B service/Support website suggests – Fully discharge the device. Then fully recharge the device and re-check the display.

      If this does not resolve it, you will need to get in contact with Oral-B to book it in for repair.

  23. The phone I have oral b smart 4 4000 only has one brush mode it does not cycle through the different modes. I press the on button It turns on I then try to cycle through modes but pressing the button just turns It off again. It says you can change modes through app but can’t work out how to do that there are rubbish instructions on the oral b website that are not what I see when in the app how do I make it go through the different modes.

    • Hi Philip,

      Did you set up a journey/specific program in the app for example whiter teeth or fresh breath?

      If so this is what has likely locked the modes. If you go into the app, change the journey for example by disabling it, the modes should be made available again.

      Reply
      • I did set up the toothbrush for fresh brush. it asks you to set up a journey when you start. I did not realise that meant I could not use the other settings the app or information leaflet should tell you that. I shall go in and end the journey and see if that resets it. Thank you very much for the help.

  24. Our toothbrushes “talk”. Many times ,in the middle of the night, I’m leaving the bathroom after a quick potty break and both toothbrushes flash all lights two times. I’ve seen this happen at 2am and at 6am, so far…its kinda creepy. My husband teases that they “are talking to the mother ship”.

    • I am not sure Mary. I have not ever seen anyone report this before. Could you have spilt something on the cord? Is it close to something pink?

      Reply
    • Mary, mine has also turned pink. A vibrant pink. Even the plug is turning pink. The base unit is not. Very strange. The entire length and the plug. We keep it in a dark drawer when not used. No other products could spill on it – and to be covering the entire length is so weird.

  25. I have the oral B Genius 6000 for about 2 years now but recently it build a black junk around the base. how do I remove it? i tried soap and water but doesn’t seems to work. do I need to open it to clean even inside? Any recommendations? Thank you.

    Reply
    • Hi Joseph. Do you mean the base where the charging stand fits into or the base around the bottom of the brush head? Do you have a small brush or something you could use to perhaps try and dislodge it? Does the brush get time to dry properly between uses?

  26. Water leaks from my oral B handle, same with my daughters and grandsons. I read a comment that said they fixed the problem with the newer models. Have you tested them? I’m going to inquire about replacements since all 3 are still under warranty.
    The leaking makes the brushing process messy. Thanks

    Reply
    • Marylin. If you have water entering into and escaping from the actual brush handle, I would advise speaking to Oral-B. This is not right or normal.

      Reply
    • Hi Julie.

      What you are saying is that the power adapter on the Oral-B charging stand will not remain fitted to the power outlet on the wall?

      Is this a brand new Oral-B toothbrush/charger or one you have owned for a while?

      I am presuming it is a 2 pin US power adapter on the charging stand?

      Have the pins on the power adapter been damaged in any way?

  27. Well, Jon, answer to your question and adding more details. After it shuts down, no more power even if I press power button again. I keep it in its base all the time, to see if maybe it will charge completely.

    Reply
    • Thank you for the extra information. It sounds then like it is a battery problem. Potentially the battery is failing. If you keep it on the charging stand all the time, the battery should be fully charged and last longer than a minute or so.

      If your brush is within its warranty period, I suggest sending it back to Oral-B for repair.

      You can find your local service agent & book in for repair with details provided online at service.braun.com

    • Hi.

      Sorry to hear this. Can you give a bit more information on what happens? It is turning itself off after say 1 minute?

      If you press the power button after it turns itself off, what happens?

      Any battery warning lights etc?

      Reply
  28. Jon, it hasn’t been constantly on the charger when its charged I leave it til it almost out of battery juice then I charge it. Didnt want it to overcharge. The only thing it does is when you put it on the charger the Bluetooth lights flash randomly it seems. Power button doesn’t work. My last Oral b had worked for 18 years, thats why I purchased a new one. My husband’s still works his is going on 19 years!!!

    Reply
    • How long have you left it on the charger for? A good few hours?

      Has the brush been dropped or sustained any damage?

      Do you get any feedback from the button when pressed? Does it sound like it tries to start? Does the battery icon flash?

  29. I have two identical Oral-B 9000 units with ring base inductive chargers type 3731. Recently one of the chargers has been making a very quiet sizzling sound inside the plug-in portion. It is still charging fine, but I am nervous. Any suggestions?

    Reply
    • Richard.

      The fact it is still working is a positive sign, but as I am sure you know a sizzling sound with electronics is not ideal, particularly if it is a product like this that can become exposed to water. I would suggest it is potentially better to be safe than sorry and replace the charger.

    • Does the head appear to fit normally? Is it a secure fit or loose? Any strange noises?

      Does the metal shaft extending from the motor inside the handle seem to be intact and positioned correctly?

      If all appears normal then I suggest you contact Oral-B.
