The 3 BIG questions about the Sonicare for kids electric toothbrush
If you are short of time, the answers to the following 3 questions should let you know all you need to about the Sonicare for kids electric toothbrush (HX6321/02). If I have missed something, let us know in the comments.
If you want more detail, you can read my full Sonicare For Kids Connected review further down the page or watch my video review.
1. Is there anything drastically wrong with this toothbrush?
No. As far as I am concerned, this is the best electric toothbrush for children.
It offers a fantastic clean, is interactive and offers the encouragement that is required to get kids brushing their teeth.
Although I would have like to have seen a couple of extras in the box.
2. Which other brushes should I consider?
My honest opinion is not to consider any other, I think this is the best brush out there for kids at the moment.
However, there others you can consider, one of the best being the Oral-B Stages Power.
Sadly, there is no Bluetooth connectivity, but there is a similar level of interaction and focus on achieving the best brushing routine for children via the Disney Magic Timer app. Brushes come in different designs featuring popular Disney characters.
There is too, the Oral-B Kids 3+, but it doesn’t offer the same value for money as the Sonicare or the Stages Power.

And now for a bit more detail….
Technology has made learning and education more fun, interactive and rewarding for children.
The problem is that there is now a high standard and expectation from children when it comes to learning something new. Getting kids to brush their teeth can be a real struggle for parents as young children just do not understand the importance of proper and regular brushing.
Thanks to the Sonicare for kids connected toothbrush things are a lot easier. It uses Bluetooth connectivity and a smartphone app to get your beloved offspring brushing their teeth perfectly.
A very fun and interactive game centered around the main character Sparkly, gets the kids engaged and wanting to brush better and for longer.
Variants of this brush
There are, at the time of writing, 3 different variants of this toothbrush.
Those vairants are:
- HX6321/02 – 1 x brush handle and 1 x kids standard brush head
- HX6392/02 – 1 x brush handle, 1 x kids standard and 1 x kids compact brush head
- HX6325/70 – 2 x brush handles, 2 x chargers, 2 x travel cases and 5 x kids standard brush heads
However, there is 1 model that is most widely stock and the most commonly purchased. That model is the HX6321/02.
The HX6392/02 is an attractive option if you have multiple children in the family, but usually, buying 2 of the HX6321/02 models is cheaper.

Design, usability, clean & general use
Where electric toothbrushes for adults tend to be finished in white or have soft pastel shades, the Sonicare for kids connected brush employs much bolder colours, as is typical for children’s products. Bold and eye catching, the primary being green/turquoise or aqua as Sonicare call it.
The overall shape and size of the brush is fairly typical of what you might imagine for an electric toothbrush, whilst the handle is not completely round it is loosely shaped like this.
The back and sides of the handle are this aqua colour, with the rear having a large number of raised dots that run down from the top to the bottom in essentially 3 rows, with each dot staggered in its positioning.
About halfway down the handle, a further 2 rows of 5 dots are added to widen the gripping area in line with where the fingers tend to naturally fall.
At the neck of the brush on the rear is a slight protrusion which looks a bit odd in its shape, but it is actually designed so that when the brush is laid flat, it will not roll.
When looking at the handle side on, you notice that the middle of the grip bulges ever so slightly too, to make it a little larger in hand. This works for kids and grownups alike and is particularly useful when hands are wet.
The base of the brush is wider in design, giving a solid base on which the brush can stand upright. The handle slims as you move up to the neck, the point at which the brush heads attach.
On the front of the Sonicare for kids Bluetooth connected electric rechargeable toothbrush are 2 prominent Green buttons that are convexed. The top button is the power button, whilst the lower button is the cleaning modes.
I will explain what they do in more detail shortly, but both have LED lights built into them and a good tactile and clicky response.
Surrounding these buttons and dominating the front of the brush is a white panel, which is a gloss white and smooth to the touch. However, this is where the Sonicare for kids gets interactive.
Provided in the box is a gloss white plastic panel, which itself fits around the buttons and the front panel of the brush. But, also included is a sheet of 10 stickers, which fit to this removable panel.
Children can choose the sticker they like most, stick it to the panel and hey presto the brush is now even brighter, bolder and more personal. Parents will really need to do the fitting of the stickers.
These stickers can be easily pulled off and replaced.
28 extra stickers (2 sheets of 14) of Sparkly, the character from the app are also provided, in various sizes. Kids may want to stick these to other things.
On the base of the brush aside from the regulatory information and product details that are printed, is a recess into which the prong on the charging stand that is provided fits.
Thanks to inductive charging, the battery inside the brush charges without having to physically connect a power cable to the handle itself. Itis possible to get up to 3 weeks use from the brush in between charges. More on this in the battery section of the review.
As a children’s Sonicare toothbrush, in the box with the brush handle is a single brush head, designed for kids, but is considered their larger/standard sized brush head.
Sonicare does manufacture compact sized heads, suitable for younger children. However, these are not in the box and have to be purchased separately. They are difficult to source too.
I think this is a real shame.
Given that this brush is for kids aged 3 years and older, it would be nice to have the smaller head suitable for these young ones in the box ready, but sadly not.
Whilst the smaller head is better for younger children, it is up to you or your child as to which is more comfortable or best to use on a daily basis. The larger head is likely to be better for those children aged roughly 6 years and up who are more independent and able to brush on their own.
The heads can be purchased in packs of 2 and cost roughly $20, making each brush head $10 each.
HX6032/94 is the official Philips Sonicare product code for a pack of 2 smaller heads, whilst HX6042/94 is the code for the standard sized heads.
Because they are designed with children in mind, unlike the regular Sonicare brush heads, these are finished with a rubber coating that not only matches the colour scheme of the brush but makes it softer on the mouth and gums of children, than the normal plastic finish.
Replacing the head every 3 month’s is the recommendation. Unlike other brushes, there are no indicator bristles that fade over time to act as a reminder to change the brush head. However, the smartphone app (more on that shortly) does remind you, if you want it to.
It’s a shame these are not included and is a bit of an oversight in teaching children about general oral health.
To replace the head, you simply pull the head off and push it back onto the metal shaft that protrudes from inside the brush handle.
You might be interested to know that the full range of Sonicare brush heads fits onto this brush handle. You do not necessarily have to use those designed for kids.
The kids heads come in packs of 2.
As you might expect of a Sonicare brush, this provides an excellent clean to the teeth and it offers up to 31,000 brush strokes (62,000 movements) per minute through the brush head.
By pressing the power button on the front of the brush handle, the brush launches into a 2 minute cleaning cycle.
As it is pressed, the LED icon on the button will light up Green.
In the lower third of the brush handle is another button, this is the cleaning mode button.
The brush offers 2 modes. Gentle and Extra Gentle.
The gentle mode is the most powerful clean offered by the brush and is designed for older/independent brushers. The cleaning cycle is 2 minutes.
Extra Gentle mode is a reduced power mode used for training and introducing children to the sonic experience. When in Extra Gentle mode, the brushing cycle is initially set at 1 minute and slowly progresses to 2 minutes over time, to help young children reach the dentist recommended 2 minutes per brushing cycle.
This ramping up of power and brushing time is a feature known as ‘Easy-Start’ which is seen on many Sonicare brushes and makes for a more natural transition from a manual to a powerful sonic brush. This happens over the first 14 brushing sessions.
You change the cleaning mode before you power the brush on. There is an LED on either side of the button. The left LED when lit, shows that the Extra Gentle mode is selected. The LED on the right when lit, shows that Gentle mode is selected.
Press the button just once to switch modes. You can’t change the mode when the brush is switched on.
2 minutes is the dentist recommended cleaning time and this brush has a built-in timer to ensure kids brush correctly for 2 minutes.
From the moment the brush powers on the timer begins working. At 30 second intervals, a sound is played to indicate it is time to change the area of the mouth that is being brushed.
The mouth should be broken up into 4 sections, known as quadrants. You have the upper right, upper left, lower right, and lower left. 30 seconds should be spent on each quadrant. The built-in timer encourages this.
At the end of the 2 minute cycle, the brush automatically turns off to signal the end of the clean and conserve battery power. A feature I love.
As if the brush was not already pretty good at encouraging your child to brush with the stickers, coloured handle and timer, the killer feature is the Bluetooth connectivity.
Download the free Sonicare Kids app from the Google Play Store or iTunes and the toothbrush connects via Bluetooth to your mobile device, be that a smartphone or tablet. Your mobile device must have Bluetooth 4.0 to work.
The principle here is that the Philips Sonicare kids rechargeable toothbrush with built-in Bluetooth connects to the app and provides an interactive on-screen experience when brushing via a character named ‘Sparkly’.
It is essentially a story based theme where Sparkly hatches and it is up to the child to take care of him.
From within the app you create user profiles for each child that will use the brush handle and then as they brush on-screen graphics and tutorials teach the child to brush correctly and for the right amount of time.
The app monitors cleans and tracks the performance for you to review if you wish.
Because the brush is connected to the mobile device, it knows when it is switched off and encourages the child to brush for the full 2 minutes.
Providing they do, they are rewarded with prizes within the app that allow them to customize and improve the experience, whilst being provided with educational tips along the way.
Watch the following video to get a great insight into how it works.
It is a well thought out app with settings parents can configure such as brush head reminders and notifications for missed brushing sessions.
Living in a world where kids are exposed to a lot of interactive content, the app needs to be good and I believe this is extremely good with the Bluetooth being that extra safety net as it actually communicates with the app for a more accurate and real-time user experience.
The downside is your smartphone or tablet needs to be in the bathroom as your kids brush, a thought some may dread, but you may supervise them during this time anyhow.
A smartphone or tablet stand to hold it at the ideal viewing angle would be useful, but no such solution is provided by Sonicare or other brands for this age group.
Kids love the interactivity and the story and it, without doubt, makes brushing fun and the children do pay attention and brush for longer with more smiles and fewer tears and tantrums at having to brush. You and your dentist will see the results.
A feature that is missing, but it not essential is a pressure sensor. A well implemented sensor will light up and alert the brusher, in this case, the child that they are brushing too hard and could be doing damage to their teeth and mouth. This is not a common feature on Sonicare brushes and I suspect left out as there are more important and valuable parts to the education program on brushing teeth than the pressure used, at this stage.
The handle itself is waterproof and will survive a rinse under the tap. It should not be submerged in water though.
A 2 year warranty is provided, should something go wrong. This does not cover user damage as you might expect.
Provided in the box are small plastic travel caps that fit over the bristles on the brush head only to protect them when travelling.
It would be nice if a more standard travel case was provided as this would not only protect the bristles but avoid accidental activation of the brush when in a bag.
Not that a child is going to pack a toothbrush first, but if staying at a friends, for example, a proper case would protect the handle more. The provided caps are just too small and easy to lose.

Inside the handle of this brush is the battery.
It is a rechargeable Lithium-Ion battery and not a user replaceable battery.
Sonicare claim up to 3 weeks battery life and our very own hands-on testing confirms this.
A total of 21 days of use, or 42 brushing sessions each lasting 2 minutes is possible from the Sonicare for kids connected handle, that is with the Bluetooth functioning.
This gives a total of 84 minutes of use before the brush needs to be recharged.
My own hands-on testing surpassed this by a long way.
I achieved 138 minutes of usage time. That is 69 cleaning sessions, which is just shy of 5 weeks use before a recharge was required. Near enough 2 weeks more than Sonicare advertise. Do I happen to have a particularly good battery in this brush handle?!
Whatever, I think it is safe to say you will easily enjoy 3 weeks between charges and quite likely longer.
Supplied in the box is a charging stand, which the brush can sit on when not in use. It is perfectly fine to top the brush up and use it again before the brush is fully recharged, if required.
A full charge can take up to 24 hours.
The stand itself is White in colour and has a prong on the top of it that fits into the base of the brush handle. The handle will sit upright on the stand.
Wired into the charging unit is a power cable that is about 1 meter in length and has a 2 pin connector on the end of it. Plug it into the mains socket and you are good to then charge the brush.
Thankfully, if you do travel and need to take the charger, you need only a plug adapter and not a voltage adapter as the charging stand itself supports voltages from 100-240v.
The LED on the power button is what shows you the status of the battery.
When turned on the LED will shine green.
When placed on the charging stand it will flash green but stop flashing when the brush is fully charged. 2 beeps are also heard when the brush is first placed on the charging stand.
If the battery power is low, that LED will flash red for a full minute after a clean to show it is low and needs recharging.
Should it be completed discharged a series of 5 beeps will be heard twice. The brush will not function and it must be put on the charging stand.
3 weeks is a good battery life.
This is particularly useful as kids might not be too proactive at putting the brush on the charging stand regularly and as a parent you need worry a lot less of coming into the bathroom to find a flat/discharged brush.
Summary of battery life
- 84 minutes of usage time or 21 days usage based on 2 cleans a day claim Sonicare – Own hands-on testing surpassed this by a long way
- Lithium-Ion battery – not user removable
- Green light flashes when charging
- 2 beeps emitted as the brush is first placed on the charging stand
- When fully charged the green LED stops flashing
- Red light flashes rapidly for 1 minute after a clean when the battery is low
- When the battery is flat, 2 sets of 5 beeps will be heard at the end of a brushing session or when new brushing session is attempted
- Can be left on the charger
- Takes up to 24 hours to charge fully
- A charger included in the box
- Works on 100- 240 volts
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.
You might be thinking that all these features come at a price and they of course do.
The retail price is $59.99, which I think is actually very good given what you get and when you compare it to an equivalent adult toothbrush.
However, unlike some brushes that are discounted, the Sonicare for Kids connected appears not to be subject to regular discounts. You may save $5-10 if you time it right, but don’t expect massive savings.
One extra factor to consider here is the cost of brush heads. These need to be replaced every 3 month’s and the average price per head is $10.
Assuming an average purchase price of $60 for this model, plus the cost of the replacement brush heads over 3 years, you are looking at a total outlay of $170, which is $0.16 per day.
Sharing the brush handle with another child in the home is one way to get extra value from the brush. Of course, you will need to purchase and use different brush heads for that child.
It is logical to make a comparison to the Oral-B equivalent. By going with Oral-B you might be roughly $30-40 better off over 3 years, but I think the premium is well worth paying given what is on offer here.
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 $59.99
- List of retailers here
- Brush heads approximately $10 each
- Works out at around 16 cents per day over 3 years
- Good value all things considered
- Share brush handle to extend value
Reliability & long term use
Only long term testing can really tell how well the Philips Sonicare for kids Bluetooth connected rechargeable electric toothbrush, HX6321/02 will last, but there is a limit as to how long I can test this for and also report back how well it performs.
I have had this brush on test for a month and during this time I have not had any concerns or reason to question the reliability of this brush.
At the hands of children a toothbrush like this is likely going to have a bit of a tougher life than it might if used exclusively by an adult. But, with the solid build and rubber grip the brush is protected as best as it can be from knocks and drops.
Whilst the provided 2 year warranty does not cover user damage it does cover any mechanical faults that come as a result of poor workmanship or faulty parts.
Typically Sonicare brushes tend to be very reliable and is most certainly highly praised for reliability and quality here at Electric Teeth and by our readers.
This is pretty much as close at it comes in my mind to being the perfect electric toothbrush for kids. It is a bold, funky and interactive toothbrush that is fun for kids of all ages, but offers an educational factor too.
A smaller brush head and maybe a travel case would have been nice, but the price is reflective of you get.
Sonicare have taken their experience in the electric toothbrush market to create a brush that ticks so many boxes for kids, parents and dentists.
If you want an easier experience when it comes to brushing your children’s teeth, this is what you need.
