Oral-B Smart 5 5000 review 1

A solid mid range brush that offers more than the basic

star star star star star

A superb toothbrush, that is arguably better than models more expensive than this.

The handle is slim and light and cleans the teeth really well, whilst giving features not found on the most basic toothbrushes.




Slim handled brush with good grip


No cleaning mode labels


2 week battery life


No dedicated cleaning mode control button


Connects to smartphone


No real-time tracking

Other brushes to consider

The Smart 5 is a really great toothbrush. If offers more features than you need. But, if you want advanced tech, the iO Series 5 might well be a better option. It offers real-time tracking of the toothbrush, showing you how to increase your brushing coverage, the Smart 5 doesn't do this.

But, for most people, it is the Oral-B Pro 3 3500 that is the brush to go for.

It doesn't have Bluetooth technology but retains the slim profile, good battery life, great cleaning results as well as the other dentist recommended features.

The Pro 3 3500 ultimately delivers great performance for the money and is our best overall option for an electric toothbrush today.

Design, usability, clean & general use

What makes a brush appealing to one person, might not be what another person finds nice to look at or hold.

For example, Philips Sonicare DiamondClean or the Kolibree Ara both have a much more minimalistic and smooth to the touch look than the Smart 5 5000.

However, personally as clean looking as they are, I like the 5000 as in my mind it is just a touch more practical.

With the 5000, running down the handle is a piece of soft touch rubber.

Oral-B Smart 5 5000 review 12

It is white in colour, but it is grippy and has a series of ridges around the power button that help hold and guide you to the controls of the brush.

The DiamondClean and Ara do not have this.

On the back of the handle is a harsher but still practical, series of grips.  Raised plastic notches, give the fingers sticking points on the upper half of the handle.

For me, these are small practicalities that make a big difference in everyday life.

A brush can look the part, but if you feel uneasy using it what’s the point?!

Now the standard Smart 5 5000 does look very clinical in all white. Aside from the white rubber grip, the plastic body is a gloss white too.

If you are looking at the dual handle pack that is the 5950, you get a splash of colour in the form of the second handle that has a pink rubber grip.

Oral-B Smart 5 5000 review 13

Like the models below it in the range, the button and icon layout is identical.

Positioned almost at the top of the handle is a power button that is white in colour with a grey/black power icon on it.  This icon helps it stand out against all the white. It has a nice resistance when pressed.  Not too soft that it can be accidentally activated, but not too firm it is difficult to press.

Above and below this power button are contours in the rubber that drive the eye and the finger/thumb to it.

Oral-B Smart 5 5000 review 14

The lower third of this Oral-B smart toothbrush handle has the Bluetooth, Oral-B and Braun logo in grey/black as well as a battery and charging icon below them.

These icons are transparent and have an LED light behind them that illuminate at certain times.

Oral-B Smart 5 5000 review 15

There are 2 parts to the brush, the handle I have been describing, that has all the clever bits of technology in, and the detachable brush head.

Sealed inside, these parts are protected from water and moisture.  This means that the brush is water resistant and can be rinsed under a tap and used in a shower.

I would always advise on avoiding submerging the brush below water, for example in a bath.

On the very bottom of the brush handle is a recess, into which the pin on the charging stand connects to.

Right at the top of the brush handle is a metal prong, this is what the brush head connects to and feeds the power from the brush motor.

Just below this metal prong on the rear side of the handle is the pressure sensor.

Oral-B Smart 5 5000 review 16

A plastic panel that is a red/orange colour, it sweeps up over and down the neck of the handle.

When you brush, sensors within the brush detect if you are being a little firm and applying too much force to your teeth.  When it detects this, it activates the pressure sensor.

This means that the LED sat behind the panel lights up so you notice the bright red light.

You should also notice that the speed of the brush head will decrease and the sound of the motor will change.  This is nothing to worry about.  It is programmed to do this, until such time as the pressure is relieved.

It does this to protect you.  You see, applying too much pressure when brushing is a big issue and it causes more damage than you might think.  A brush need only skim the surface of the tooth and gums.

Just relieve the pressure and the light will go out and the motor power up again.

Don’t worry if you activate it often, over time you will learn and avoid doing lasting damage to your teeth.

One of the main appeals of the Smart 5 is the multiple cleaning modes that it offers.

It offers 5 in total.

They are:

  • Daily Clean
  • Pro Clean
  • Sensitive
  • Whitening
  • Gum Care

Remember the order of these, you will need to refer to this in a moment.

Oral-B Smart 5 5000 review 17

Each mode works slightly differently, with differing levels of oscillations, rotations and pulsations to achieve different cleaning effects on the teeth.

For example, Sensitive mode reduces the number of movements to be softer on the teeth and gums.

You can find much more detail on each mode and how they compare in our cleaning modes explanation.

To activate each cleaning mode, you have to use the power button on the front of the brush.

Remember the list above, this is the order of the cleaning modes.

Press the power button once to turn it on.  Daily Clean mode will launch.

Press it again to change the mode to Pro Clean.

Press it a third time to activate Sensitive mode.

A fourth time to get whitening and a sixth for Gum Care.

A seventh and final time will turn the brush off.

You can press and hold the button for 2 seconds at any point to power it off.

Now, I don’t know if you have spotted the 2 issues I have.

The first is that to change to any of the cleaning modes, you first have to power the brush on and the second is you need to remember the order.

I suspect over time you will learn this, but where can you refer to this order?

The manual is the only place.  Thus for some time, you are probably going to need to keep this nearby until you are proficient with the order.

It would be nice to have another button and/or a way of selecting the mode prior to actually turning the brush on.  Sadly this is not the case.

Do remember to put the brush in your mouth before powering on and changing modes otherwise the toothpaste might go flying across the room.

Oral-B Smart 5 5000 review 18

The more premium Genius 9000 has a benefit in that the brush handle has icons that show the cleaning mode selected.  However, you still need to switch the brush on to change mode.

One other difference is that the 9000 will remember the last cleaning mode used and will launch back into that, but the 5000 will not.

This means if you want to use the Gum Care mode most often on the Smart 5, it is a total of 6 times before you are ready to brush.

A bit of a negative, maybe the 5000 can win you back with the fact that when you are using it, it is very good and your teeth and gums do feel good post clean.

The handle offers some 16 days of battery life and is lightweight.

When the battery built into the brush begins to deplete, the charging icon will flash Red.

You do not get anything more detailed from the handle.

It would be nice if you had a green light to suggest a good amount of remaining charge or yellow for less than 50% for example, but no such luck.

Even better would be a little LED display that showed the exact battery percentage (%).  Or in the case of the Smart 5, the app picked up the information.

Oral-B Smart 5 5000 review 19

The battery icon will flash green when the brush is on charge.

As I previously mentioned, the brush heads are interchangeable on the Smart 5.  In the box, you do get 3 different styles of heads (the dual handle 5950 has only 1 style).

Each brush head can actually be used with any of the cleaning modes, but some heads work best with specific modes.  For example, the 3D White head will work best with the Whitening mode and the Sensitive with the Sensitive cleaning mode.

To fit or remove the brush head simply align the metal with the hole in the shaft of the brush head and push the two together until you hear and feel them clip into place.

Pull the two apart to release them.

It is important for your oral health to replace your toothbrush head every 3 months or sooner if your bristles are frayed.

Official Oral-B brush heads are recommended and they all have something known as indicator bristles.  These are blue coloured bristles that will over a 3 month period gradually discolour.

When they are a very pale blue or white it is time to change.  It is a clever reminder system.

The interchangeable nature of the brush heads does mean you could use other brands brush heads, such as Molarclean for example.

Do be aware fading bristles are not necessarily a feature of other brands and Oral-B themselves do not encourage use of alternatives.  However, there is money to be saved.

There are 6 main styles of brush head:

  • CrossAction
  • FlossAction
  • 3D White
  • Sensitive/SensiClean
  • Precision Clean
  • TriZone

Want to know the differences in detail? Read our comparison of Oral-B brush heads.

All of the brush heads provide a good clean.  My personal favourite for everyday use is the CrossAction head.

Oral-B Smart 5 5000 review 20

Despite being noisier than most other brands, I personally prefer the clean offered by Oral-B.  It feels like a deeper clean.

Studies have suggested Oral-B’s oscillating and rotating technology is superior, but there are studies that side with Sonicare.  It’s more about what you prefer.  Either way, you will get a better clean than a manual brush.

Most cleaning modes on this brush for 2 minutes.

Hopefully, you know that the recommended brushing time is 2 minutes, twice a day.

If you didn’t or are guilty of not brushing for as long as you should, the Smart 5 can help in 2 ways.

The first is the built-in timer and quadpacer.

Imagine your mouth broken up into 4 sections. Upper right, upper left, lower right and lower left.

You should spend 30 seconds cleaning each section.  The pacer helps you keep an even brushing time on these 4 sections.

At 30 second intervals, the brush will provide an audible warning via a slight pause in the brush motor at to tell you to change quadrant. Once the 2 minutes are up 3 brief pauses in the brush motor will be heard and felt.

Brushing for the full 2 minutes is very important, but just as important, if not more so, is the right technique. Make sure you learn how to clean your teeth properly.  You can learn here.

Oral-B Smart 5 5000 review 21

The second way in which it helps is through the more powerful Bluetooth connectivity and smartphone app.

It is by no means a new feature, it has been on brushes since the Oral-B Pro 6000, but in the last 18 months or so it has undergone a good deal of improvement.

It is now found on more brushes as there is a greater call for ‘Smart’ and ‘Connected’ products.

The 5000 is an Oral-B smart toothbrush.

The idea behind this connectivity is to essentially be a little like having a dentist or hygienist looking over your shoulder saying good, bad, brush for longer, you missed a bit.  It is about education for better cleaning rather than telling you that you have got it all wrong.

To take advantage of this, you need an Android or iOS smartphone and Bluetooth 4.0 on your phone.

Download the appropriate app and install it on your phone.

You can download from iTunes here and Google Play Store here.

As good as the app is, I feel this is too one of the negatives as some will not see the point of using it or find it more hassle than it's worth.  You don’t have to if you don’t want to.

If you feel you won’t use it, you may want to consider if the Smart 5 is for you, you will be paying for a feature you won't necessarily use.

It takes a bit of practice to get in a routine of having your phone with you when brushing.  If you forget it or don’t have it to hand, don’t worry.  The handle will store the data for the last 20 cleans and sync this to the app, the next time it connects.

The app is very comprehensive with lots of options. It gives you all you need though to not only effectively brush your teeth, but to log the cleans and motivate you.

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.

At times I have found these distracting, you may want to customise the settings to avoid some notifications.

You can also set personalised modes which can disable cleaning modes on the brush handle too.

Sadly the app does not show the battery power of the brush handle.

The main feature of the app is the on-screen timer and guide that shows you where to brush and how well you have brushed.

A nice in box addition is the smartphone stand.

It looks a little like a large white puck.  It holds a smartphone in either portrait or landscape orientation.  It should accommodate most phones.

A point to note is to be a little careful when in the bathroom as unless your phone is water resistant, you might want to make sure it is positioned away from a sink or bath.

Because brush heads are interchangeable it is possible to extend the value of a toothbrush by sharing the handle amongst a number of users.

However, if each user intends to use the Bluetooth feature, then it is necessary that each user has their own handle.  The 5000 cannot handle multiple user tracking (there is an option, but its far from ideal).

This one user principle applies to all Bluetooth enabled brushes I have tested to date.

As a result, this is one of the reasons why the 5950 package exists as you get 2 brush handles, meaning 2 users can now track their cleans.  Rather frustratingly though, the box contents does not include a smartphone stand and I think a more unisex colour other than pink might have been better for the second handle.

Extra items that come in the box with both the Smart 5 5000 and 5950 are a charging stand, travel case and brush head storage compartment.

The charging stand is fairly self explanatory, but I explain more about this in the battery section of the review.

As 3 brush heads are included with the 5000, the provided storage compartment holds up to 4.

Complete with a lid, it protects the heads from splashes but allows airflow around them to allow them to dry and stop bacteria buildup.

The way in which this compartment has been moulded is such that it fits perfectly around the charging stand, to create a kind of desktop home if you like for the brush handle and heads.

Oral-B Smart 5 5000 review 38

The travel case is perfectly acceptable, holding 1 brush handle and up to 2 brush heads.  This is supplied with the 5000 and 5950.  It is transparent and does not allow for in case charging like the Genius X and iO Series 9.

However, now with 2 weeks of battery life, this is less of an issue.

In the unlikely event, something goes wrong, there is as standard a 24 month warranty is provided with the 5000.  This covers the battery too.  Register the brush online and you get an extra 12 months at no extra cost, so 36 months or 3 years in total.

One final thing to be aware of is that there is a 30 day money back guarantee on offer from Oral-B.  It is essentially like a trial, whereby you can buy and try the Oral-B smart toothbrush.  Should you not like it you can return it for a refund.  This is particularly useful if you are unsure whether an electric toothbrush is for you.

Summary of design, usability, clean & general use

Slim and comfortable brush to hold and use
5 cleaning modes (Daily Clean, Pro Clean, Sensitive, Whitening and Gum Care)
3 brush heads included (1 x CrossAction, 1 x Sensitive/SensiClean & 1 x 3D White)
The dual handle 5950 will include either 2 x CrossAction or 2 x Sensitive brush heads instead
Need to switch the brush on to change cleaning modes
No way to easily tell which mode is being used
Built-in quad pacer and 2 minute timer tells you when to change quadrant and finish brushing
Bluetooth connectivity with an app for logging and coaching
Not all will find the app useful
Smartphone stand included, but not with the 5950.
Travel case and brush head storage compartment included
Water resistant and can be used in the shower

Battery life

To date, with the exception of the Genius brushes, all others used a battery type known as Nickel Metal Hydride (NiMH).  

Although okay, this battery technology has really been superseded by Lithium-Ion (Li-Ion) batteries.  These are the types of batteries we find in our smartphones.

As a result of this change, the Smart 5 and other models now have been upgraded and have a battery life more fitting of their price tags and able to better compete with other brands.

For some time now the likes of Sonicare and Colgate have put Oral-B to shame when it comes to battery performance.  In fact, many offer 3 weeks of battery life, so the Oral-B is not a chart topper at this time.

Oral-B have generally remained dominant because most of us do not travel enough to really NEED the extended life and there has quite often been a price or feature advantage.

Oral-B Smart 5 5000 review 39

The older SmartSeries 5000 offers 7 days use or 28 minutes of actual usage time.

With the Smart 5, this has more than doubled.

In our testing, we were able to get 66 minutes of usage time from the rush, which equates to 16 days use.

The 16 days we measured is based on one user brushing twice a day for 2 minutes.

Various conditions may affect this quoted usage time, but safe to say you are getting at least double the performance, yet despite the battery change the physical size of the brush handle has not altered.

On the brush handle are 2 icons that light up, a battery icon and a charger icon.

When the battery is low, it is the charging icon that will flash red.

Sit the brush on the provided charging stand and the battery icon will flash green.

Made of plastic, the charging stand has a prong on the top, on which the Smart 5 will sit to be recharged.  This aligns with the recess in the base of the Smart 5 brush handle.

This charger has a power cable that will typically connect to a power socket found in a bathroom.  The 2 pin connector works on 220-240v and can be connected to a 3 pin UK socket with use of an adapter.

It usually takes up to 15 hours to recharge the brush fully.  It is a relatively slow charge that is pushed to the brush via the charging stand, so it is perfectly safe to leave the brush on here at all times when not in use.

Summary of battery life

Newer Lithium-Ion battery technology used
66 minutes of usage time or 16 days usage based on 2 cleans a day
Can be left on the charger
Takes up to 15 hours to charge fully
A charger is included in the box
The status icon flashes green when charging and red when the battery is low
Works on 220-240 volts
Competition still offer up to 3 weeks usage

Price & where to buy

I have included links to buying options here at the start of the review.

In the section below, I discuss the price more generally and in relation to similar products.

The Smart 5 5000  has a recommended retail price of £169.99.  

I would normally expect you to be able to purchase this for anywhere between £80-100.

At the time of review, the price is remaining unusually high, at £120 and above, but I suspect in time things will change, as most Oral-B brushes you can buy at 40-60% below the RRP.

Oral-B Smart 5 5000 review 40

Prices will vary from store to store.  Quite often online retailers will have the best price, but often high street retailers like Superdrug and Boots run promotions which result in much lower ticket prices.

Whilst I really like this brush for its box contents and features, it does have some shortcomings and you need to weigh up in your own mind what it is worth and what you are prepared to pay.

At £100 you are still getting an excellent brush, but when retailing for over £100, this opens the door to a few other equally capable brushes that have some other potential benefits, notably the iO Series 5 and 6.

This brush like every other requires replacement brush heads for each user every 3 months.  Replacement heads can be purchased in packs of 4 and are priced on average between £11 and £14.

We like to price this brush over a 3 year period, but to do so works on an average selling price.  I am making assumptions in this calculation that the cost will drop to around £85 which is roughly half the RRP.

Using the average cost (based on one user) and ownership over 3 years (the same as the warranty period (if registered online), the Smart 5 5000 will cost £119 or 11p per day to own.  

This price does exclude the cost of water, toothpaste and electric to charge it.  This price also works on some assumptions, but you get a rough idea.

You can bring the cost down further if you were to share it with other members of your household.  All you need do is invest in extra brush heads.

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 £169.99
Expect the sale price to drop to around 50% of the RRP, circa £85
Works out at around 11p per day over 3 year

Reliability & long term use

I would love to be in a position whereby I could say to you that you are guaranteed to never have a fault with your brush.

The reality of the situation is that this brush has mechanical working parts and being able to give such assurances is impossible.

For 99.9% of users there will be years of hassle free brushing, but should you be one of the 0.01% where inevitably something does go wrong, Oral-B do not leave you high and dry.

In fact, they offer one of the best guarantees available.

Oral-B Smart 5 5000 review 16

For a start, right out of the box you have a 2 year warranty.  No registration needed (until you need to log an issue).

You can, however, register your brush online and get another 1 year (12 months) extended warranty for absolutely no cost to you.

Therefore should the brush fail within the first 3 years of ownership you are covered.

You can get full details of the warranty and the associated process in our guide to what the warranty covers.

The Smart 5 uses a handle design that has been tried, tested and perfected over many years and I really can’t find any obvious faults with it.  Its well built and solid in hand.

I know from past experience that most Oral-B models will survive a few falls to the bathroom floor, in most instances.


Personally, I think the Smart 5 5000 offers an excellent all round package.

The implementation of cleaning modes on the 5000 could be better for sure and a better travel case would be preferred, but all told I am really impressed.

Since initial launch, newer models like the iO5 and iO6 have come along and are compelling alternatives. They deliver the same sort of cleaning experience but have a bit more tech for little difference in price.

The final decision will be personal preference and price.

Hi John, I hope you are well. I am really confused between the oral B pro 2 2500 and the oral-B Smart 5 5000. Is you were to recommend one of these two, which one would it be?

Jon Love - Chief tester
November 14, 2020

Hi Lara. The Oral-B Pro 2 2500 would be my recommendation. Both are excellent toothbrushes and will clean the teeth well. The Smart 5 5000 offers extra features, that the vast majority do not need or will not use. There are exceptions of course. But, feedback suggests many don't stick to using the apps and extra cleaning modes. The Pro 2 2500 is a more cost-effective option. You are paying for what you will need and use and nothing more. If you have any questions, do let me know.

Purchased the smart 5 5000 27|12|2019. Returned 32 days later to Argos. Would not retain charge! Exchanged it for same model. Happy with experience of the machine. So thought give it another try!

Hi Graham. Thanks for the feedback. Sometimes faulty ones slip through the net. Hopefully, the replacement will be just fine.

January 24, 2020

If the price was the same, what would you suggest me between the smart 4 and the smart 5?

Jon Love - Chief tester
January 27, 2020

If the price is the same, I would go with the Smart 5 Simone as you get more in the box Simone.

January 27, 2020

Thanks Jon. Comparing The smart5 to the oral b's top rated toothrush, It has all the same modes (exept the tongue cleaner), same numbers of pulsatinos/oscillations, lithium battery and smart features. I've found a special offer in which the smart5 is almost the 40% cheaper than the genius 10000. - It seems to be a complete electric toothbrush with negligible differences compared to the genius ones (tounge mode, design, specific modes bottom, batter travel case). Would I do a good deal if I bought that smart5? - Considering the numbers of pulsations/oscillatings, could I substitute the tongue mode with sensitive mode? Is there any relevant difference between these two modes?

Jon Love - Chief tester
January 28, 2020

Simone. I would go with the Smart 5. With the Genius 10000 you do get 'real-time'/position detection tracking when a smartphone is placed in the holder and you stand in front of the camera. This is supposed to help you brush better. However, you don't need this and from what you suggest so far it is not something you are looking for. You could easily use the sensitive mode, to replace the tongue cleaning mode, you don't necessarily need a specific mode. Many clean their tongue with the brush turned off or on a standard daily clean mode.

R. Sawston
August 28, 2019

My wife and I have found after a few weeks the use of the genius 9000 series has made our teeth very sensitive, the dentist suggests it may be the more powerful oscillation and pulse rates, even with sensitive tooth brush and sensitive tooth brush settings. After talking to Braun/Oral B they say all of their toothbrushes with new batteries have this higher rate so we have gone back to using our old braun tooth brush, when this completely dies we will have to change to something different.

April 8, 2023

Do you have any details on the charger for this toothbrush? Which oral-b models can use the same charger as this on?

Jon Love - Chief tester
April 10, 2023

Hi Luke. Almost all Oral-B rechargeable electric toothbrushes can use this charging stand, the main exceptions being the Oral-B iO Series 7, 8 & 9. Pretty much any other models should fit & work on the charging stand provided with this brush.

Hi I am confused btn 5000 and 5000n which is the latest version and the one to get as price varies hugely

Jon Love - Chief tester
May 6, 2019

Hi Tracy. The newest/latest version in the UK is the Oral-B Smart 5 5000/5000N as per this review. Sometimes you will see it referred to or labelled with N and other times without. The N relates to the crossaction brush head supplied. There are older versions known as the Oral-B SmartSeries or Pro 5000/5000N.

February 18, 2019

Just a heads up: The Currys price embed under "Price & Where To Buy" is incorrectly for the "BABYLISS Thermo BAB3045 Ceramic Rollers". (Which explains the £30 price tag)

Thanks for this. Now adjusted. 👍

November 17, 2018

The Smart 5 5000 seems to have a higher ptich noise when running the same cleaning mode compared to the 2500, or 2000N. Is that normal? Is it due to different number of oscillations? I'm concerned it might have something wrong with it. thank you.

Jon Love - Chief tester
November 19, 2018

Hi Caitlin. The Smart 5 5000 has the same number of movements/oscillation as the Pro 2 2000 and Pro 2 2500. I can't say I have noticed a difference in the sound running the same cleaning mode, but then again I have not done a direct side by side comparison and analysed thoroughly. Therefore I would suggest it's poossibly not normal, but then again I haven't done the comparison head to head. Is the sound difference significant? If you are using different brush heads that may or could have some bearing.

Hi could you reassure me that the Smart 4000 and 5000 have Daily Clean mode as first switch on mode like my Oral B Pro 4000 which is the older version P.S one other question I always have my electric toothbrush on charge as it sits on my dressing table and I just run it down every 6 months as stated in manual but I have now been told by Google search that I shouldn't be doing this and to take it off charge each time I use it I did notice that the last time I let it run down it slowed down after a few days Sorry for all the questions I'm a worrier and the general rule of thumb was to just run it down every 6 months Many Thanks Wendy

Jon Love - Chief tester
October 17, 2018

Hi Wendy. The Smart 4 4009 and 5 5000 have the daily clean mode set as the first cleaning mode when you switch the brush on. In regards to the battery advice has been to run the battery down every 6 months or so. However with new models this is not necessary.
