Oral-B Junior Smart Oral-B Junior Smart 6,690 Reviews £40.00

In this review, I am testing and giving my feedback on the Oral-B Junior Smart electric toothbrush.

Not to be confused with the original Oral-B Junior. The original Junior brush available in purple or green and reviewed here is designed and performs differently, not to mention, it’s not smart.

I am writing this review from the perspective of a parent, as although your little one will no doubt have a say, one assumes it will be you who has the final decision!

The 3 BIG questions about the Oral-B Junior Smart

If you are short of time, the answers to the following 3 questions should let you know all you need to about the Smart Junior toothbrush from Oral-B. If I have missed something, let me know in the comments.

If you want more detail, you can read my full Oral-B Junior Smart review further down the page. 

1. Is there anything drastically wrong with this toothbrush?

No there really is not.

It is a superb electric toothbrush and trying to find fault with it is really quite difficult.

2. Which other brushes should I consider?

The most similarly featured alternatives are the Oral-B Teen or Smart 4 4000 as they are for the most part identical to the Junior Smart.

Or you can consider the Philips Sonicare For Kids Connected brush.

The Sonicare is my recommendation for the best toothbrush for kids, but this Junior Smart is really targeting the slightly older children who still like interactive engagement but are more capable and disciplined and want less parental interaction.

If Bluetooth connectivity really is a desire, then the Junior Smart sort of stands on its own, with a more funky brush handle design.

You could consider the Oral-B Pro 3 3500. It lacks the Bluetooth/smart features, but it cleans just as well and will likely save you a few quid also.

If your child will not use the app with the Junior Smart, the Pro 3 3500 is a good money-saving option.

3. Where is the best place to buy the [insert]?

Oral-B electric toothbrushes tend to be widely stocked.

The larger high street chemists like Boots should stock it along with many of the major supermarkets, but availability can vary from one store to another and sometimes particular models are not stocked due to the broad range of models.

Online retailers like Amazon do stock all variants, so them and other large online retailers are often a good route to go as they can be quite price competitive also. It’s always worth checking out eBay, too.

Oral-B Junior Smart Review

And now for a bit more detail….

As stated on the box, the Junior Smart has been designed with children aged 6 years and over in mind.

Typically, children need assistance from parents when brushing their teeth up until the age of about 8 years old. But, come 6 years old, routine and probably a bit of parental nagging has kicked in and they are doing a pretty good job themselves.

The Junior Smart offers a product that is still child friendly, but has been refined to be more mature and more ‘cool’ than the bright coloured handles typically applied to younger children’s toothbrushes.

Believe it or not the only thing, from what I can tell, that makes this toothbrush geared to Juniors is the design on the brush handle. It even has the same sized brush head you would find on an adults Oral-B toothbrush.

Children’s mouths at this age are getting larger as they grow and can generally accommodate a larger brush head, but the round head is smaller than most toothbrush heads.

To put it bluntly, the Junior Smart is a repackaged Oral-B Smart 4 4000, which is marketed for adults. The same can be said of the Oral-B Teen. 3 toothbrushes that are technically the same, just small design and box contents differences set them apart.

Variants of this toothbrush

At the time of review, there is only 1 variant of Oral-B Junior Smart.

That 1 variant is the model I am reviewing here and you see photographed throughout.

However, now seems an appropriate time to clarify where some possible confusion may occur because there are multiple products named Oral-B Junior, yet they are different.

There are 3 other models which could all to easily be confused with the Junior Smart, because they all have Junior in the name.

  • Oral-B Junior Sensi UltraThin – Green – £49.99 RRP
  • Oral-B Junior Sensi UltraThin – Purple – £49.99 RRP

These 2 models look very different and are technically very different to the Junior Smart. There are a couple of common features as there are with most electric toothbrushes, but the big thing to note here is that they do not have Bluetooth connectivity and the battery life is inferior.

I have been hands on with this variant. Read my review of the Oral-B Junior.

  • Oral-B Junior Star Wars – £79.99 RRP

Stylistically this looks very similar to the Junior Smart, but the handle features a Stormtrooper from Star Wars, the brush has 1 less cleaning mode and no Bluetooth connectivity.

What’s in the box?

  • Braun Oral-B Junior Smart rechargeable toothbrush
  • Charging station
  • 1 x Sensi UltraThin
  • Documentation
Oral-B Junior Smart laid out with box contents

Key Features

  • Oral-B 3D movement cleaning system (Oscillating-Rotating-Pulsating)
  • A superior clean than a manual brush
  • Rechargeable battery
  • 3 cleaning modes (Daily Clean, Sensitive & Whitening)
  • Visible pressure sensor
  • Clean timer including quadpacer
  • Battery life in excess of 2 weeks
  • Bluetooth connectivity and smart coaching

Pro & Cons

Here are what I consider to be the pros and cons of the Junior Smart.

The Positives

  • Design – A slim profiled brush that looks and feels good in the hand with a nice design flare.
  • Battery life – A solid 2+ weeks between charges.
  • Pressure sensor – A rear mounted pressure sensor illuminates red should too much force and pressure be applied to the teeth. Acting as a visual indicator you are clearly made aware to reduce the pressure and chances of doing damage to the teeth.
  • Bluetooth connectivity – Allows the child and the parent to track the cleaning time, brushing pressure and more, whilst making for an engaging brushing experience.
  • Timer & pacer – Help encourage brushing for the right amount of time.

The Negatives

  • Additional cleaning modes – Given the target age group of this brush, I don’t think the additional cleaning modes are all that necessary, particularly the whitening mode.
  • Not easy to tell what mode is selected – There are no icons on the brush handle to alert you or make you aware of which of the 3 cleaning modes is actually selected.
  • No dedicated cleaning mode button – You have to use the power button to change the modes and can do so only once the brush is switched on.
  • Price – Potentially quite an expensive model for children of this age.

Design, usability, clean & general use

The physical packaging of the Junior Smart very much fits in with typical Oral-B colours, Blue.

However, unlike the boxes designed to grab the attention of adults, the background to the Junior Smart box has faded comic style illustrations of teeth, mouths, water, toothpaste and more that just give it that edge and makes it stand out from the rest.

Oral-B Junior Smart box / packaging

As the ‘what’s in the box’ section will show, you don’t get an awful lot supplied, but then again you don’t necessarily need a lot.

Now, there is much to like about this brush, but before I explain what the brush handle is like to hold and use, let me just touch upon the fact that the Junior Smart is essentially a repackaged Oral-B Smart 4 4000.

This is in many ways very clever and a practical choice by Oral-B, but in another way it is potentially a little deceitful as you could pay a premium for the Junior Smart when you could buy the Smart 4 4000 that I have reviewed.

What sets the 2 models apart is that the Junior has a design on the handles rubber grip that is appealing to children and the box contents of the Junior contains a little less (1 less brush head and no brush head stand). As far as I am aware, everything else is the same.

Thus as you may well imagine, there isn’t all that much that is aimed at kids with this brush.

Perhaps including some sort of child friendly paper based brushing guide would just add that extra edge to make it a bit more engaging for the child from the moment it gets taken out of the box.

But, it is not as bad as it may seem. I will explain why throughout the remainder of this review.

Oral-B Junior Smart standing upright - full height shot

In hand, the Junior feels good, solid, durable and practical.

The body of the brush handle is primarily plastic in construction, a gloss white plastic. The front of the brush handle has a large rubber grip that runs down it and the back of the handle has a series of raised plastic ridges. Together these act as gripping points to keep the brush secure in hand.

The handle is the same size as an adult toothbrush, but it is rounded in its design and fairly slim so there is no reason why most children could not hold onto this toothbrush comfortably.

To make this Junior model stand out and appeal to the intended age group, there is a decal/pattern that is centrally placed within the white rubber grip that runs down the front of the brush handle.

Close up of Oral-B Junior Smart decoration on handle

The hands on images show this best. Essentially printed on the grip is what looks like a load of doodles. This design contains illustrations of teeth, toothpaste, toothbrushes and similar things in different colours (blue, purple and green). It is certainly a bit different and adds a slight fun element to the handle.

The rubber grip runs top to bottom on the front of the brush handle.

In the upper third of the handle is the main power button that turns the brush on and off and allows you to select the cleaning modes available.

Above and below the button are a series of ridges that help your child grip the handle and guide their fingers to the controls of the brush.

The power button is white in colour with a blue power icon on it. The contrasting colour of the icon helps it stand out against all the white body.

With a convex design the button stands slightly proud and has a good level of resistance, meaning it’s not too easily activated by mistake, but easy enough to press to stop and start the brush motor.

Sitting a little below the power button, just before the decal kicks in, is a Bluetooth logo, giving an indication to the smart capabilities this brush has.

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

Oral-B Junior Smart laid diagonally

These icons are transparent and have an LED light behind them that illuminate at certain times. I will explain what these lights mean in the battery life section of this review.

The back of the brush handle has these raised horizontal notches that give the fingertips grip. These run from the top to about halfway down the handle.

Oral-B Junior Smart rear, full height

Right at the bottom of the back of the handle is a small notch. It might look slightly odd and out of place, but lye the brush flat and this stops it rolling about.

The sides of the handle are smooth to the touch, bar the small embossed ‘Professional Care’ wording on each side.

What is quite obvious is the red panel on the back of the brush handle. Positioned at the neck, just below the attachment point for the brush head, this is the visible pressure sensor, that lights up red when activated.

Oral-B Junior Smart pressure sensor close up

I will explain how it works in more detail shortly, but the panel does taper from the back of the handle into the sides just a little.

The handle will stand upright on a flat surface, despite having a recess in the bottom into which the protuberance (prong) on the charging stand fits.

Sealed inside the brush handle is the rechargeable battery, the brush motor and other electronics.

At the top of the handle extends a metal shaft that is connected to the motor. It is to this that the brush heads attach.

The Junior Smart comes supplied with a single Sensi UltraThin brush head.

You simply push this head onto the brush handle and pull it off again when you want to remove it.

It clips into place quite securely. You can quite easily tell when it is fitted correctly. There is no need to twist or lock it in place.

This brush head is just 1 of a range of different styles of brush heads offered by the company, but for kids it is ideal thanks to the super soft bristles.

Close up of Oral-B brush head

You can select a different style of head from the range if you prefer, but for the more delicate teeth and gums of your child, it is best to stick to a soft bristled head.

All of the Oral-B heads are interchangeable and work on any of the cleaning modes the brush offers.

On average, the brush head should be used for 3 months before being replaced.

If the head becomes damaged or worn sooner, it should be replaced as it could otherwise be damaging the teeth and gums.

Close up of Oral-B Junior Smart on its side

I hardly doubt your child will ask for a new brush head, so checking when a new one is due falls on your shoulders as the parent. The good news is there are a couple of things that can help you out.

The first is within the app, there is the facility to set a reminder. Essentially you can set the date you fitted the head and the app will throw up an alert when it is due to be changed.

The bristles on the brush head themselves fade also.

The blue tips of the bristles over a 3 month period will gradually fade. As they become more translucent and the blue colouring fades away, this is another visual reminder to you that it is time to swap the head.

One of the things that wears brush heads out sooner than 3 months is excess pressure being applied to the teeth.

Bristles of the brush essentially need only skim the tooth surface to clean away debris and plaque. This then is where the pressure sensor comes in.

Close up of Oral-B Junior Smart from behind showing pressure sensor and brush head

Should the brush detect that too much pressure is being applied to the teeth as it is in operation, a number of things will happen.

Firstly, the red light on the back of the handle will light up. The movement of the brush head will slow down and one dimension of that cleaning action, the pulsations, stop altogether. If the app is being used at this time, a message saying reduce pressure will also be displayed.

Once the pressure is relieved, the light will go out, the brush head will speed up again and normal brushing is resumed.

This pressure sensor is very helpful in getting kids to understand brushing pressure, as the light is engaging and a clear visual stimulus to what is right and wrong.

The pressure sensor works on all brushing/cleaning modes available on this brush.

Full height side shot of Oral-B Junior Smart with brush head on

The Oral-B Junior has 3 brushing modes. They are:

  • Daily Clean
  • Sensitive
  • Whitening

The names pretty much explain what they are designed for.

I personally don’t think that children aged 6+ really need additional modes, just the standard daily clean is enough.

However, Sensitive is a slower and more gentle mode, so this can be better for those children who may find the brushing power a little too much, so I will cut Oral-B some slack here.

But the whitening mode really is redundant in my opinion.

Any toothbrush used correctly can whiten teeth, by removing stains that exist on the outside surfaces of the teeth. A specific whitening mode is going to make little different. It will not change the natural colour of the teeth. Whilst it is good to ensure staining is being removed from the teeth, does the very presence of this mode reinforce the theory that we must have bright white teeth?

Oral-B Junior Smart Review 1

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 Sensitive

Press it a third time to activate Whitening mode.

A fourth time will turn the brush off.

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

This makes sense, but there are 2 issues in particular that I have with the way in which this has been configured.

The first is that to change to any of the cleaning modes, you first have to power the brush on, you can’t change the mode before turning the brush on. And the second is you need to remember the order. There are no icons of ways to make things clear which mode is selected.

Now, being transparent, it will show you in the app if you have that running at the same time, but something on the handle would be nice.

The brush does also remember the cleaning mode last used, if a full 2 minute cleaning cycle is completed. So, if the sensitive mode is used and the cycle is completed, it will default to this mode the next time the brush is switched on.

A small point to note is that this brush does not automatically power itself off at the end of the 2 minute cleaning cycle, like some other brushes do.

Oral-B Junior Smart Review 2

Despite my comments about the modes and the way you control them, the cleaning action of the Oral-B toothbrush is excellent.

Clinically proven to be very effective, although the Junior actually has an adult brush head supplied, the small round shape makes it perfectly easy for most kids (and parents) to move this around the mouth, reaching all the teeth, front, back and biting surfaces also.

It can take some getting used to as it is quite different to a manual toothbrush, but after a week or so most have gotten used to the power and sensation.

You can’t change the amount of power other than selecting a different cleaning mode, for example,, the Sensitive mode.

As a parent, you might be aware, but if your child has only ever used a manual brush, the technique to use an electric brush is different.

Oral-B Junior Smart Review 3

I suggest you familiarise yourself with how to brush with an electric toothbrush, so you and your children can achieve the best oral care standards.

Now, I expect you know first hand of the struggles that can ensue with getting your child to brush their teeth at all, let alone properly.

This is where a few features really start to show their worth.

These features are the 2 minute timer, quadpacer and the smartphone app.

Most cleaning modes on this brush run for 2 minutes.

Oral-B Junior Smart Review 4

If you did not already know, this is the globally recommended brushing time. 2 minutes, twice a day.

2 minutes to a child might apparently be a lifetime, but the Junior Smart has a couple of tricks to help them keep brushing for this long.

The first is the 2 minute timer itself. Once the 2 minutes are up 3 brief pauses in the brush motor will be heard and felt, so you can get your child to listen out for this and then they know not to stop brushing before this happens.

But there is also the a quadpacer, also known as a professional timer built-in, that kicks in at 30 second intervals.

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

The principle is that we humans should spend 30 seconds cleaning each section. The pacer helps 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 that acts as a sign to change quadrant.

Oral-B Junior Smart Review 5

Now, if your child uses the app this can help even more so than the built-in timer, because there are more visuals to go with it.

Essentially, the app points to the section of the mouth requiring cleaning at that time.

The Bluetooth keeps everything happening in real-time.

Now, Oral-B have 2 apps. There is the standard Oral-B app for Android and iOS which all of their Bluetooth connected brushes work with. And there is also their FunZone app.

As the name implies it is more interactive and ‘gamifies’ the brushing experience, perfect for kids.

Whilst either app can be used, the FunZone app will deliver the best results for kids, I do believe.

Depending on the age of the child may depend on whether they have their own mobile device, but for now I will surmise they are using your mobile phone.

It takes just a couple of moments to get the app installed and setup, it is really easy.

You do have to give certain permissions to the app to allow it to function to its full potential, including access you use your front facing camera.

In principle the idea is the phone is in front of the children as they brush. The camera puts them into an onscreen experience and even records a little video of them brushing.

As it does this, the timer is functioning and graphics come up on screen to show them where to brush.

Points are awarded for achieving certain goals, like brushing for the right time etc.

Over the days and weeks, the points add up to unlock new on screen experiences and rewards. Brushing streaks can be unlocked giving what I can only describe as virtual stickers that are shown within the app.

The app will provide advice and tips to help the child (or adult) brush better and know how they can improve.

As each brushing session is completed it is logged within the app so a record of brushing sessions are recorded.

This could potentially be useful to you as an adult to see if your child did brush and for how long, but you can potentially use it with the dentist also.

The app is kept fairly simple, so as not to over complicate the usage.

I do like what Oral-B have done here.

Please be aware that whilst the toothbrush and smartphone communicate, this brush is unable to track the exact position in the mouth, so the data is only a guide only. Unless supervising your child you will not know precisely how well they have cleaned each area of their mouth.

As a parent myself I don’t necessarily like my child being in front of a screen, but I do see the implementation as educational.

You don’t have to make use of the app, but failing to do so would mean you are not getting value from this toothbrush.

The brush handle will retain up to 30 days brushing data, so if the phone is not available during brushing sessions, the data will be transferred to the app, the next time it connects. Please note, this functionality works best with the standard Oral-B app. The Fun Zone app seems inconsistent and in my testing logged only data recorded in real-time as I used the app.

There is no charge for the app, and there are no in app purchases.

You do have to have an Android or iOS mobile device with Bluetooth 4.0 or above (most newer phones fall into this category).

It would be useful if Oral-B provided a stand in the box to mount the smartphone in or on, so the child or you as the parent doesn’t have to hold the phone the whole time. But, the different bathroom setups, heights of kids etc can make it difficult to position it correctly, so maybe in hand use is best.

Oral-B Junior Smart Review 12

Built into the brush handle is a rechargeable lithium-ion battery. This should give 16 days of usage, based on 2 cleans per day, each lasting 2 minutes.

You don’t get lots of battery feedback. It does not in the smartphone app, for example, show precisely how much power remains. That said when the power is low the battery icon on the front of the handle will flash red, warning you that a recharge is ideally required.

No travel case or brush head storage option is provided in the box.

You do have the charging stand that the brush can sit on when not in use.

Oral-B offer a 2 year warranty as standard, which can be extended to 3 years, at no cost if you register the brush.

Battery life

Given that the Junior Smart is essentially based on the current series of adult toothbrushes from Oral-B, this brush benefits from a reasonable battery life.

Oral-B claim 2+ weeks, which in reality means approximately 16 days, based on 2 cleans per day each lasting 2 minutes.

Oral-B Junior Smart Review 13

Very few brushes offer less than 2 weeks battery life today. It is certainly the average, and in fact the average is increasing to 3+ weeks in my opinion.

Sonicare’s connected toothbrush for kids has a claimed battery life of 3 weeks, but in my hands on testing lasted a whopping 69 cleaning sessions, which is just under 5 weeks. That is almost 2 weeks longer than the claimed battery life.

Now, to be fair to Oral-B, in my hands on testing, the Junior did exceed the claimed 16 days, achieving 21 days in total (84 minutes of usage time or 42 brushing sessions).

This is actually the longest battery life I have gotten out of any Oral-B toothbrush.

I am not sure how, or why this brush lasted quite so long, when similar models use the same battery and have always run out of power around the 16 days.

I cannot guarantee you will get the extra 5 days usage from the brush like I did, but it will certainly achieve a little over 2 weeks.

It is a lithium-ion battery that the Junior Smart uses. It is rechargeable and sealed within the handle. It is not designed to be removed, without invalidating the warranty and potentially breaking the brush.

Oral-B Junior Smart Review 14

When the battery power is low, the charging icon will flash red. It is at this point really that you want to get the brush on the charging stand as the motor slows a bit, giving a weaker cleaning action otherwise.

If the battery is completely flat, it can take 30 minutes or so before any icons light up when placed on the charging stand.

When sat on the supplied charging stand, the battery icon will flash green to alert you to the fact it is receiving charge.

It takes about 12 hours to fully charge the battery.

Once fully charged, the battery light will turn a solid green. It will shortly turn itself out entirely.

The brush will stop receiving charge once full, so you need not worry about overcharging it. Just be aware if it is on the stand and the light is not flashing, the brush is either fully charged already or so flat it needs longer on the charging stand.

It is perfectly safe to leave the brush on the charging stand at all times.

Oral-B Junior Smart Review 15

The charging stand is made of a white plastic. It has a prong on the top, on which the Junior will sit to be recharged. This aligns with the recess in the base of the brush handle.

This charger has a 2 pin power cable, that is designed to connect to a power (shaver) socket found in a UK bathroom.

The 2 pin connector is not a 2 pin European plug.

The 2 pin connector works on 220-240v and can be connected to a 3 pin UK socket with use of an adapter, if you don’t have a 2 pin ‘shaver socket’ in your bathroom.

Oral-B Junior Smart Review 16

If you intend to go overseas with this toothbrush, maybe on a family holiday, you might need to consider the charging stand. The brush may have enough power to last the holiday or you may need to take it with you.

Wherever you go as a minimum you will require a plug adapter, or possibly a voltage adapter also.

Summary of battery life

  • Lithium-ion battery technology used
  • Claimed 16 days of battery life, based on 2 cleans a day
  • Actually achieved 21 days in hands on testing
  • Can be left on the charger
  • Takes up to 12 hours to charge fully
  • A charger is included in the box
  • Charger icon flashes red when the battery is low
  • Battery icon flashes green when on charge
  • Works on 220-240 volts
  • Competition still offer over 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.

Electric toothbrushes have a recommended retail price (RRP) set by the manufacturer, in this case it is £79.99.

Whilst it does vary from one retailer to another, in reality, the actual selling price is quite often 50% less, particularly with Oral-B.

This applies to almost all their brushes, very rarely do you have to pay the full price.

Oral-B Junior Smart Review 17

Therefore in this instance, I would expect this to be around £40.

This is in fact the exact price I paid when I purchased this brush on the day it launched in the UK.

I was not given this brush as a gift or sample from Oral-B.

At £40 this might seem quite pricey for a child’s toothbrush, particularly if you compare it to a manual brush. However, this is an exceptional price.

At this price, it is one of the most affordable smart toothbrushes available from a leading brand.

Philips Sonicare brushes tend not to be discounted as heavily as Oral-B. Their connected kids brush has an RRP of £73 and tends to sell for about £50. You can see the similarities in pricing from Oral-B here.

Oral-B Junior Smart Review 18

The best prices tend to be found online, but the high street do quite often offer good pricing also; but they are more likely to stick closer to the RRP.

It is a good few weeks between my purchase of this brush and the writing of this review, as I test each model.

What is slightly odd, is that the Junior Smart has returned to its RRP at all of the retailers selling it at the time of review.

I imagine the price will drop again, but perhaps Oral-B are trying to retain more profit margin?!

At £79.99, to be fair you still get an excellent toothbrush. I am not saying it is not worth it at this price, but when one is so used to the heavier discounts it doesn’t come across as quite such a good buy.

Oral-B Junior Smart Review 19

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. As a rough average 1 replacement head costs about £3.

To try and give a bit of a benchmark for comparison, I do calculate the cost of owning this brush over a 3 year period. I usually base this off the discounted price, but in this instance I will calculate the full RRP and discounted totals.

If you pay the full £79.99 and add in the cost of the extra 11 brush heads needed over 3 years, the total ownership cost would be £112.99 or 10p per day.

Oral-B Junior Smart Review 20

Based on the discounted price of £39.99, this would work out to £72.99 or 7p per day.

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.

For comparison’s sake, the Sonicare for kids brush works out at 12p per day. The brush heads for Sonicare are quite a bit more expensive than Oral-B.

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

  • Live price comparison here
  • Recommended retail price of £79.99
  • Should generally be available with 50% or more off RRP; circa £40.
  • Works out at around 7p per day over 3 years

Reliability & long term use

I would love to be able to put every brush that comes through the Electric Teeth offices through long term tests, but sadly there are only so many brushes I and others on the team can test on the long term.

I would also love to say that the products we buy to last forever, but this is not the case.

Oral-B Junior Smart Review 21

Every brush that I test, I check over for obvious signs of weakness or defects.

The very nature of being an electronic item with moving parts does indeed make the brush susceptible to failure. However, the reliability of Oral-B products tends to be very good.

It is often thought that the typical life of an electric toothbrush is around 3-5 years, although I do believe that improved product quality and parts means that many more are lasting in excess of 5 years. I would suggest the average life is now more like 5-7 years.

After 5 years you should have gotten good value from the toothbrush, and this Oral-B brush comes with a 2 year warranty as standard. Go online and register the brush and this can be increased to 3 years at no extra charge.


The Oral-B Junior Smart (view on Amazon) is an excellent electric toothbrush, particularly if you can buy it for around the £40 price point.

It cleans really well, has a good battery life and feels good in the hand

The accompanying smartphone app is fun and engaging as well as being educational and offers the engagement that kids will enjoy.

Whilst I have a few complaints about the brush, they are in reality very minor. They could well be overlooked, some might argue that I am being picky.

Although marketed for Juniors, aside from the pattern on the handle, there is nothing else about this that is specifically geared towards the younger generation, but I don’t think it matters that much.

This is certainly best for older children aged 6 years and up, both from a design, usability and smartphone application point of view. It is not suited to children younger than this.

For this reason, you could save money by going for an adult brush, the Pro 3 3500. It does not have Bluetooth so will not work with the app, but if the app is unimportant to you or your child, there is a cost to be saved.
