Oral-B Pro 7500 Review

Oral-B Pro 7500 Electric Toothbrush Review - USA

A tech rich toothbrush that will make you a better brusher

4 star rating

The Pro 7500 from Oral-B is an excellent toothbrush. It offers the essential features you need and much more all focused on encouraging you to form better habits in your oral care.

Newer more advanced models now exist, which essentially replace this.


  • Multiple cleaning modes
  • Grippy handle
  • Bluetooth connectivity for those committed users


  • Bluetooth connectivity isn’t essential and adds to the cost

Other models are better investments

Make no mistake, the Pro 7500 is a very solid toothbrush that does a good job, but newer models, of a similar price offer a bit more for an enhanced user experience.

Oral-B’s iO Series 6 offers pretty much all the 7500 has to offer with a sleeker design and more accurate real-time position tracking of the brush for more insightful feedback on your technique.

You don’t need a premium toothbrush to clean the teeth well and a few $ can be saved by opting for the likes of the Oral-B Smart 1500 which has the core essential features needed, and nothing more.

Design, usability, clean & general use

Premium is most certainly a word you could use to describe the Pro 7500.

It is essentially an upgrade on the older Pro 7000 and has a number of design and feature improvements.

The body shape, style, and design are very much based on the Genius Pro 8000. It is available in 4 different color options, white (pictured), black, orchid purple and rose gold.

The white variant does look a bit clinical.

Oral-B Pro 7500 Review 1

Compared to the Pro 7000, the 7500 has a slimmed profile, with a more uniform cylindrical body shape.

It is on the front of the brush where most of the action happens as it were.

Framed inside the plastic panel is a large oval shaped piece of rubber that forms the two key functional buttons on this brush, the power and cleaning mode button.

Oral-B Pro 7500 Review 2

Under this are 4 icons, that light up to highlight the cleaning mode being used.  There are only 4 icons despite the brush offering 5 cleaning modes….

In the lower third of the panel is a Bluetooth icon, a battery icon made up of 3 bars and then finally the Oral-B and Braun logos in black color.

On the rear of the brush is a contoured rubber grip which assists when holding the brush for grip, especially when wet.  It is generally smooth to the touch but grippy with a series of indented dots.  Many other models have raised lines on the back here, but the 7500 has a smoother finish which gives it a cleaner and less rough to the touch feel.

Oral-B Pro 7500 Review 3

The base of the brush has a recess into which the prong on the charging stand fits to charge the brush.

On the neck of the brush is where you find the LED SmartRing, the component that can be customized via that app to one of 12 color options.  My personal favorite is blue.  It illuminates when in use and should the pressure sensor be activated it will illuminate red.

Oral-B Genius Electric Toothbrush - Smart Ring, Choose from 12 Colours

A fully sealed brush it can be used in the shower, rinsed off under a tap etc without issue.  The plastic and rubber are resilient to the water, bacteria, and toothpaste that it will come into contact with.

The 7500 measures and weighs and ergonomically comfortable 24cm tall with the brush head attached and 2.7cm wide and 3.2cm deep and weighs 140 grams.

To get going and start using the brush you need to press the power button. Holid it for 2 seconds to turn the brush off.  The button requires a firm push, meaning it is difficult to accidentally power on or off.

To change the cleaning mode it is a case of pressing the cleaning mode button (downwards facing arrow) under the power button and continuing to press until the desired cleaning mode is reached and the indicator illuminated.  The light from the icon, is a White light.

What I can’t really get my head around is why there is no icon for the Daily Clean mode.  OK, it is the default mode but why exclude it from the icons and have one for every other mode?

The cleaning modes available on the 7500 are:

  • Daily Clean
  • Gum Care
  • Sensitive
  • Whitening
  • Pro-Clean
Oral-B Pro 7500 Review 4

The Pro-Clean mode replaces what was known as Deep Clean mode that has been available on other models.  Pro-Clean provides an intense clean feeling with 3,000 more movements per minute than the more standard Daily Clean mode.

For more information and explanation on how the cleaning modes differ, read our Oral-B cleaning modes explained article.

Each cleaning mode usually lasts for 2 minutes, which ties in with what is recommended by dentists.

The 7500 has a 2 minute timer and also a quadpacer built-in.

The mouth is made up of 4 quadrants, so you spend 30 seconds cleaning each, to make up your 2 minute clean.

As the 7500 is running as is the timer.  A short stuttering sound and flashing light of the Smart Ring at 30 second intervals alerts you to move to the next quadrant of your mouth.  A long stuttering sound and flashing light indicate the end of the professionally recommended 2 minute clean.

The timer memorizes the elapsed brushing time, even when the handle is briefly switched off during brushing. Anything longer than 30 seconds paused and the timer resets

Built into the Pro 7500 is a pressure sensor that detects and alerts you when you are brushing too hard.

A triple pressure sensor, the brush gives a visual notification via the Oral-B app and through the LED SmartRing which illuminates red.  The brush will automatically reduce the head speed and stops the pulsations until the pressure is reduced, you will also notice a change in the motor’s sound.

Once the pressure is relieved the brush will power back up again.

3 brush heads are included in the box with the 7500.  All of these have the dynamic 3D movement that Oral-B promotes.  The head oscillates, rotates and pulsates to break up and remove up to 100% more plaque than a manual toothbrush.

The following image shows how it works.

Oral-B Pro GIF

This is a proprietary technology that helps clean tooth by tooth reaching areas that are often missed and there is no denying the brush cleans the teeth really well.

Brush heads are interchangeable, so you can use those supplied or fit the head you wish to use most.  All heads will work on any cleaning mode, but some are better suited to particular modes.

The heads available are:

  • Cross Action (supplied)
  • Floss Action (supplied)
  • Pro White (supplied)
  • Precision Clean
  • Sensitive
  • Deep Sweep

The Cross Action brush head is the default if you like.  It relies on hundreds of bristles that are angled in different directions. It has been scientifically engineered, to ensure the bristles cross over different parts of the tooth surface more effectively than those brush heads that have standard straight bristles.

Oral-B Pro 7500 Review 5

Remember to replace your brush head at least once every 3 months or 90 days if not sooner. You can have the app remind you of this, or why not set up a scheduled delivery through Amazon?

An Oral-B brush head will actually fade in color as it ages giving you another visual indicator that it is time to replace the brush head.

The 3 brush heads supplied can be stored in the brush head storage compartment, which holds up to 4 heads.  The plastic tray allows the heads to lay in place and drip dry, whilst a lid protects them from dirt and other potential splashes.

Oral-B Pro 7500 Review 6

Clipping around the brushes charging stand, it makes for a neat countertop setup.

Of course one of the big draws of this brush is the Bluetooth connectivity.

A technology now found on many more models, the ethos behind it is that the app will help educate users to clean better which will result in better oral health.

A study conducted by Oral-B showed that up to 80% of people don’t spend enough time brushing, particularly spending less time on one zone of the mouth and some 60% did not brush or spent insufficient time brushing their molars (the teeth at the back).  Guess which teeth are prone to needing fillings?!

Preventing dental issues is cheaper than fixing them often, so if you can get to grips with using the smartphone app and connectivity it could be very worthwhile.

Some will see this as a gimmick and not appreciate the value, whilst others love it.  Particularly those who are ‘tied’ to their smartphone.

The app can be downloaded from iTunes or the Play Store and will run on most devices provided they have Bluetooth 4.0 or higher.

The app is very comprehensive with lots of options, too many to go through completely in this review.  It gives you all you need though to not only effectively brush your teeth, but to log the cleans and motivate you.  You will ultimately get out of it what you put into it.

There are features like integration with your calendar so you can see your days agenda, news, tips, and tricks, so you stay interested when cleaning your teeth.  Although for me, on occasions it can be a bit distracting from you ensuring you brush correctly and you may want to customize the settings to avoid some notifications.

Whilst a toothbrush plays a vital role in oral hygiene the routine and way in which you clean does too. This app makes it easy to see and represent in real time just how good, or bad you are doing.

Challenges are presented to you allowing you to obtain a score based on how well you brush and improve your habits. Brush better and for longer and you are on the road to success. Gain badges for achievements and share socially if you chose.

Sensors in the brush provide real time information to the app that then gives you suggestions and tips.

If you have perfected your technique you may have less to gain than others, but I was impressed at just how well the app works and monitors you clean, it still had areas where I could improve!

Oral-B Pro 7500 Review 7

The app is deeper and more intelligent too.  You can customize the brush and personal goals through the app gaining more suitable tips and advice along with product suggestions. For example, if you wish to whiten your teeth the app will advise and amend your routine to achieve the goal.  You can choose from the Fresh Breath Gum Health, Plaque Fighter, Whitening and Ortho Care journeys.

Online backup is another feature that ensures you never lose data and even share with compatible services for additional insights and benefits.

As the app logs data over the days and weeks, it is impressive to see through the logs how your habits and brushing time changes.

Whilst you need to launch the app each time to use it the brush itself can store the data for up to 20 cleans meaning you do not need to always have the app to hand.

It is also worth noting, whilst it is perfectly possible to share a brush handle, the handle can not differentiate between 2 users, so your data synced to the app will be wrong (unless there is a way this can be done that we could not find).

What I feel is missing from all of this is a stand for the smartphone.

The Genius Pro 8000 offers a suction cup smartphone holder which is clever and beneficial but takes some real commitment to use.

Globally some other models come with a desktop mount to hold the phone but the 7500 does not.

Therefore to really make use of the app, you need to hold your smartphone in one hand whilst you brush with the other.  I think this is a bit awkward and is an oversight on Oral-B’s part.

If a small smartphone stand was provided, it would encourage people to use it more, particularly as it keeps a hand free and alleviates some of the fear people have of having their phone in the bathroom.

The 7500 does boast better battery life than its predecessors, 12 days of battery life in fact.

Included in the box is a charging stand that should be used when the battery requires replenishment.  Thankfully you do get a bit of feedback from the brush with battery status, more on this in the ‘Battery Life’ section of the review.

Oral-B Pro 7500 Review 8

In the box with the 7500 to is a travel case.  A bit better than the ones I have seen from Oral-B before but it is still a cheap piece of molded plastic compared to the very desirable travel case that comes with the Genius Pro 8000.

Best described as a white, branded plastic box that holds the brush and two brush heads, is all that is needed but is not as heavy nor does it have the soft touch premium feeling of that supplied with the 8000, nor does it allow the brush to be charged in the case.

Most importantly however it is functional.

Summary of design, usability, clean & general use

  • Available in White only
  • Grippy rubber on the rear ensures the brush remains in hand
  • Comfortable to hold
  • White illumination for cleaning modes, power indicator etc.
  • Dedicated power and cleaning mode buttons
  • 5 cleaning modes – Daily Clean, Gum Care, Sensitive, Whitening and Pro-Clean
  • Icons for only 4 of the 5 modes
  • 3 brush heads included (more available to purchase separately)
  • Brush head storage compartment for up to 4 heads
  • Built-in quadpacer and 2 minute timer
  • Pressure sensor that illuminates red for pressure and green on a quadrant change
  • LED SmartRing that can be customized 1 of 12 color options
  • Bluetooth connectivity to record your brushing history via app for Android and iOS
  • The app promotes the right idea but the hassle of using, the inaccuracies and desire to work with the app can work against the long term goal of better oral health
  • No smartphone holder/stand
  • Basic travel case that holds the 7500 and 2 brush heads

Battery life

One of the biggest appeals of the Pro 7500 has to be the fact that it uses a newer type of battery inside the brush handle.

For many years Oral-B has (and still do in some models) use Nickel Metal Hydride (NiMH) batteries.  Whilst functional, over time they do degrade and have been met with criticism

Brands like Colgate and Sonicare have been using Lithium-Ion batteries which are much more reliable.  This is the same battery technology used in your smartphone.

The 7500 is one of a number of brushes from Oral-B to now feature the lithium technology which helps improve battery life and usable life.

12 days of usage time is possible from the 7500 based on one user cleaning their teeth twice a day for 2 minutes.

Somewhat short of the 2-3 weeks offered by some competing models, it is an improvement over most other Oral-B brushes that last 7 days.

48 minutes of cleaning time is more than enough for most people, especially when the provided charging stand is usually fairly close by and the 7500 gives a bit more feedback than some other brushes.

If you travel a lot or need a particularly long battery life maybe this is not for you.

The charging dock itself is white in color and has a small prong on the top which aligns with a recess in the bottom of the brush handle and will charge the brush fully in about 12 hours.  I tend to leave it on charge overnight. When charging the battery charging icon pulses with a white light.

Oral-B Pro 7500 Review 9

When power is low the battery status icon will flash and you will likely feel the decrease in brush power. When depleted completely the motor will power down and the battery icon flash red.

If completely dead, it will need at least 30 minutes on charge before it functions again.

What I would really like to see given the brush communicates digitally with the smartphone is a bit more detailed battery status, such as a percentage (%).  Is it 20%, 15% or 7% left, surely this is possible.

Oral-B Pro 7500 Review 10

The battery is built-in and is not user replaceable unless you want to invalidate your warranty and are confident with electronics and soldering.

To ensure that the battery holds its maximum capacity, at least once every six months, charge the battery fully and then let it discharge until it no longer functions.

Summary of battery life

  • Uses a lithium-ion battery
  • Battery is built-in and not user replaceable
  • Takes about 12 hours to charge fully
  • When completely flat at least 30 minutes of charge is required
  • 48 minutes of usage time or 12 days usage based on 2 cleans a day
  • Battery status icon flashes with a white light when charging and red when the battery is very low
  • Would be good if you got a percentage (%) of the remaining battery
  • Other brands typically offer better battery life

Price & where to buy

Different people have different perceptions of money and what is expensive and what is cheap.

For some $50 is a lot of money whilst for others it is small change.

Electric toothbrushes can vary considerably in price and it can be difficult to mark a line in the sand and really understand what is a fair or reasonable price for what is on offer.

The Pro 7500 is one of the more premium models.

Always subject to change the price is, but at the time of writing, its selling for around $142.

Given what is on offer, that is a very fair price and perhaps slightly below where I expected the price to be.

At Electric Teeth we understand the average life of a brush to be 3-5 years and for sake of comparison work out and compare the cost of ownership over 3 years.

Factored into this is the cost of replacement brush heads, which with Oral-B tend to cost around $5 per head.

Using the average cost (based on one user) and ownership over 3 years, the Pro 7500 will cost $197.

This is not one of the cheapest brushes to own, but it is not the most expensive either.

There is a good chance the brush will last longer than the 3 year period and using the same brush handle but switching heads with other users in your household will only help bring the cost down and drive more value from it.

Unless you really need or want the advanced cleaning modes and features this brush offers then you can do yourself the benefit of looking at a brush such as the Smart 1500 which is normally around half the price, but still offers a lot.

If you do want the very best, then the 7500 is one option for you, most certainly, but I would be doing you an injustice not to advise going for the newer models like the iO6.

It’s a similar price to buy, and might work out a bit more expensive long term, due to the heads it used, but the brush is more refined and has better real-time feedback for you to improve your brushing.

Ultimately, only pay what you are prepared to.  Make your own judgement based on your needs and wants.

Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase.  These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Summary of price & where to buy

  • Recommended retail price of approx $142
  • Replacement heads cost $5
  • Costs $197 over 3 years
  • Share brush handle to extend value
  • Consider other brushes for more value

Reliability & long term use

Whilst I would love to give you the assurances that the Pro 7500 would never go wrong to give such would be impossible.

The electric toothbrush is exposed to water and moisture and the internal parts move, are recharged and subject to heat and noise, so it is very possible that something could go wrong.

But, Oral-B products are very reliable and the chance of something failing is very slim.

Out of all the brushes I have tested I have yet to have one fail.

Oral-B produces millions of toothbrushes and have gained experience in building solid and reputable products.

In fact, the most unreliable part if is often the battery.  Whilst failure rates are still low, Oral-B have addressed this in the 7500 by using the newer lithium battery compared to the older nickel metal hydride configuration.

Backed by a 2 year warranty, should something fail you are covered.

During my hands-on testing of the 7500, I have given it a thorough check and can find no obvious weaknesses or manufacturing defects that would raise cause for concern.

A bit of advice I wish to give is to prolong the life of any brush, give it a rinse and a wipe down to remove grime that builds up.


There are potentially some faults with the Pro 7500, but what faults there are, are more personal gripes with how Oral-B have put together this brush in comparison to other brushes in the range.

Let’s be very clear here. From the perspective of cleaning the teeth, the brush is faultless. You will have healthier teeth and gums from regular use of this brush. There is no doubt about this.

Considering some other brushes will allow you to get a little extra value from your investment when models like the iO6 can offer enhanced tracking not available on the Pro 7500.

Size Guide

  • Height (without head) – 20.5cm
  • Height (with head) – 24cm
  • Width – 2.7cm
  • Thickness – 3.2cm
  • Weight (without head) – 134g
  • Weight (with head) – 140g

All are approximates

    • H Leonard.

      This is a good question and honestly I cannot give you a 100% confirmation that it will.

      In theory yes, it should and the odds of it working are much higher than it not.

      If you need further assistance let me know.

  2. Love the Oral B Professional Care that I’ve had for nearly 3 years, but the price of replacement brushes was ridiculously high. I’ve found generic brushes for 1/6th the price that are just as good. Thanks for the article
