Unrivaled sonic technology

 
Philips Sonicare electric toothbrushes have a sonic sweeping motion, with up to 62,000 brush head movements per minute. This creates gentle microbubbles for a superior brushing result and an exceptional clean feeling.

Tough on plaque, gentle on gums

 
The sonic motion gently drives fluid between teeth, even in hard to reach areas including along the gum line, while the brush gently strokes and effectively removes plaque.

Toothbrushes for extra deep cleaning
 

The combination of the motion of the brush head with the 3 minute brushing time ensures an exceptional deep clean all over.

Frequently Asked Questions

How do electric and manual toothbrushes differ?

 

There are many differences between brushing your teeth manually and 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 a 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 toothbrush mid-use?

 

Your Philips Sonicare DiamondClean 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 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 out and the handle routine will reset.

 

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

 

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

 

Change and select brushing modes

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

 

  1. Make sure that your Sonicare toothbrush is turned off
  2. Press the power button to change and select the preferred brushing mode
  3. Your Philips Sonicare toothbrush will remember the selected mode for your next brushing session.

 

Changing intensity settings

  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 assured that 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:

  1. Gently whipping toothpaste and saliva into an oxygen-rich foamy liquid
  2. Directing the liquid between and behind teeth, and along the gum line where plaque bacteria flourish
  3. Gently massaging the gums, stimulating blood circulation and helping to dislodge plaque


Sonicare toothbrushes with gum care mode

The Philips Sonicare DiamondClean 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 electric toothbrush as follows.

 

Tips and tricks:

  1. Make sure the brush head is placed at an angle between the brackets and the gum line.
  2. 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.
  3. Repeat this until you have brushed all your teeth.
  4. 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 toothbrush is easy.

 

  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 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

 

How to charge Sonicare DiamondClean while traveling?

 

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

 

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

  1. via wall outlet
  2. 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.
