Philips Sonicare BrushSync replacement reminder system


Inside the brush head is a small microchip.

When the brush head is fitted to the brush handle, the chip is detected and the warning light will flash 3 times. This acts as confirmation that the handle has detected the head and that the electronics inside the handle will now keep track of it.

As you use the brush head, the handle continues to track how often it has been used.

The handle knows that the brush head should be replaced every 3 months, so once the handle detects that the brush head has been used for this amount of time, the ‘BrushSync’ LED on the brush handle will light up an amber/orange colour to tell you it is time to change the brush head.

But, the brush is cleverer still.

If it detects you have brushed 3 times a day every day or brushed with more pressure, it will activate the BrushSync alert system sooner, as the bristles will have worn out sooner than the typical 3 month time period.

By the same token, it will delay alerting you to replace the brush head.  If you used that head just once a day over 3 months, it would not tell you to replace it until it had been used for the equivalent to 4 minutes a day for 3 months.

This is a very neat touch and shows how technology can be used in a positive way to better the nations oral health whilst also being cost effective (by not replacing brush heads too soon).

Philips Sonicare Smart BrushSync Toothbrush heads

Smart BrushSync Toothbrush heads

BrushSync is an innovative piece of technology made up of 2 different features.  They aim to bring an added convenience to electric toothbrush users.

First introduced in 2017 by Philips Sonicare on their premium model, the DiamondClean Smart, the technology is slowly being added to new brush handles as their range develops.

You can identify the Smart brush heads by the Smart icon at the base of the brush head as shown in the image below.

A microchip in the Philips Sonicare Smart brush head tells your DiamondClean Smart which brush head you are using. So if you click on a gum-care brush head, for example, your toothbrush knows to select the optimal mode and intensity for that brush head.
