Philips Sonicare’s advanced technology pulses fluid between the teeth and along the gum-line whilst sonic brush-strokes gently and effectively remove plaque to improve gum health.

Did you know?

Clinically proven for a superior clean

All Sonicare toothbrushes and brush-heads are clinically tested to consistently ensure the most effective and yet gentle clean.

Smart brushing experience, no guesswork!

Brushing correctly is important for the health and safety of your teeth and gums. Your Sonicare DiamondClean Smart electric toothbrush is equipped with up to 5 built-in smart sensors and a connected app to guide your brushing. So its right every time.
Built-in smart sensors take the guesswork out of brushing. Real-time feedback helps get your brushing technique to 100%.
The position sensor guides you to brush any missed areas. That way you can get 100% coverage, 100% of the time.
The brush head reordering service, powered by BrushSync technology, automatically orders new brush heads for you, based on your brush head's actual usage.

Different modes for all dental needs

Set the mode and intensity for the perfect, personalized brushing experience. From gum health, plaque removal and whitening, there's the ideal setting for your needs.

Brush head replacement reminder

BrushSync technology tracks how long you've been using your brush head for, and how hard you've been brushing. When it's time to replace it, a light on your handle and a short beep will let you know. That way, you can be sure your brush head is doing a good job.

Brush heads delivered to your door, right when you need them

Choose the perfect brush heads for your oral care goals and ensure you never run out. BrushSync technology automatically reorders based on your actual brushing usage and is easy to set up and manage in the Philips Sonicare connected app.

Frequently asked questions

How do electric and manual toothbrushes differ?

There are many differences between brushing your teeth manually or using a Philips Sonicare electric toothbrush. Discover all the benefits.

Sonicare toothbrushes clean differently

Electric toothbrushes clean more thoroughly in a way that manual toothbrushes cannot.

Recommended by dental professionals

Electric toothbrushes are recommended by most dental professionals to help improve oral health because they are proven to be more effective in removing plaque compared to a manual toothbrush.

Scientific proof

Our Sonic technology is backed by more than 175 clinical and laboratory studies at over 50 universities and research institutions worldwide.

Number one recommended brand

These results, along with personal experience, make Philips Sonicare the #1 recommended sonic toothbrush brand by dental professionals worldwide.

Patented sonic technology

Our patented sonic technology drives unique bristle tip velocity - the movement of the brush head in your mouth - through a combination of high frequency and high amplitude motion. This motion creates dynamic cleaning action that drives fluids deep into the tight spaces between your teeth and along the gum line, which results in a cleaner, healthier mouth.

Can I pause my Philips DiamondClean Smart toothbrush mid-use?

Your Philips Sonicare DiamondClean Smart toothbrush uses smart technology for the best brushing experience. Find out how it works.

Just press the on/off button of your Philips Sonicare DiamondClean toothbrush

Once you turn on your Sonicare DiamondClean Smart handle, you can pause the brushing after 5 seconds of use. Before the 5 seconds of use the handle will simply switch modes. To pause the brushing after 5 seconds of use, press the on/off button. To resume brushing, simply press the on/off button again and the handle will continue and finish the routine.

Please note that if the handle is paused for more than 30 seconds, the lights on the handle will fade off and the handle routine will reset.

How to change the intensity settings & brushing modes of my Sonicare toothbrush?

Find out how to change the intensity settings or brushing modes of your Philips Sonicare DiamondClean Smart toothbrush. Find the settings that fit your brushing experience.

Change and select brushing modes

To change the brushing modes of your Philips Sonicare DiamondClean Smart toothbrush, follow these simple steps:

Make sure that your Sonicare toothbrush is turned off

Press the power button to change and select the preferred brushing mode

Your Philips Sonicare toothbrush will remember the selected mode for your next brushing session.

Changing intensity settings

To change the intensity settings of your Philips Sonicare DiamondClean Smart toothbrush, follow these simple steps:
1) Turn on your Sonicare toothbrush
2) While turned on, press the power button to select your preferred intensity setting
3) Your Philips Sonicare toothbrush will remember the selected intensity settings for your next brushing session.

Can the speed of the Sonicare toothbrush harm my gums?

A Philips Sonicare electric toothbrush behaves differently than a manual one. Be sure it cannot do any harm.

Philips Sonicare toothbrushes will not harm your gums

Sonicare toothbrushes have even been shown in studies to be gentler on dentin than a manual or an oscillating toothbrush.

While gentle, Sonicare technology cleans effectively by:

Gently whipping toothpaste and saliva into an oxygen-rich foamy liquid

Directing the liquid between and behind teeth, and along the gum line where plaque bacteria flourish

Gently massaging the gums, stimulating blood circulation and helping to dislodge plaque

Sonicare toothbrushes with gum care mode

The Philips Sonicare DiamondClean Smart toothbrush come with special Gum Care and massage modes to assure even more comfort for sensitive gums. Gum Care mode provides two minutes of complete whole mouth cleaning, with one additional minute of gentle cleaning for problem areas and along the gum line. Massage mode uses our patented technology to drive fluids to stimulate gums, resulting in healthier gums.

How do I use my Philips toothbrush if I wear braces?

When you are wearing braces, brushing your teeth is not always easy. You can best use your Philips Sonicare DiamondClean Smart electric toothbrush as follows.

Tips and tricks:

Make sure the brush head is placed at an angle between the brackets and the gum line.

Using light pressure, gently wiggle the tips of the longer bristles between your teeth for 2 seconds. Then gently roll the brush handle so the bristles clean the bracket and the rest of the tooth before you glide the bristles to the next tooth.

Repeat this until you have brushed all your teeth.

Please do not force the bristles into gaps in the braces.

Philips Sonicare Mini brush head

Please note that all Sonicare toothbrushes may be used to clean around braces. However, our Mini brush head is especially suited for people with braces and other site-specific cleaning needs. It is 40% smaller than our Medium brush head and has a slightly longer neck.

How do I charge my Philips Sonicare toothbrush?

Charging the battery of your Philips Sonicare DiamondClean Smart toothbrush is easy as 1-2-3.

1) Plug the chrome base charger into a live electric power outlet
2) Place the glass on the chrome base
3) Place your Philips Sonicare DiamondClean smart into the glass in an upright position
4) The flashing light on the handle indicates that the toothbrush is charging*. If the indicator does not start flashing, keep the handle in the charger for at least 10-15 minutes to allow the toothbrush to recover
5) It takes at least 24 hours to fully charge the battery

DiamondClean Smart toothbrushes (in addition to a flashing battery indicator) will also illuminate at the bottom and you will hear a beep.

Can I charge two DiamondClean Smart toothbrushes in 1 glass?

If you have two Philips DiamondClean Smart electric toothbrushes you might want to charge both of them in one glass. Find out if you can do so.

Not the best results

It is possible to fit two Sonicare DiamondClean Smart handles in the charging glass, but you will achieve the best charging results by charging only one handle at a time when using the charger and charging glass.

How to charge Sonicare DiamondClean Smart while traveling?

When you are out and about it is nice to carry your Philips Sonicare DiamondClean Smart toothbrush with you. So you can maintain good oral health.

While traveling, you can charge your Sonicare DiamondClean Smart in two ways:

via wall outlet

via USB

To charge via wall outlet:

Place the handle in the charging travel case, plug the USB cord into the travel plug into an electric outlet. The charge indicator on the handle flashes green until fully charged.

To charge via USB:

Remove the USB cord from the travel plug, and insert the USB plug into any USB port. Use Only Philips USB wall adapter and USB cable provided. Use Only UL listed devices as an alternate method of charging the toothbrush handle in the travel care. This charger is not compatible with previous models of Sonicare.
