My handle is very loud – is this OK?


The Sonicare device is dynamically balanced to function with a brush head in your mouth. Therefore, in some cases, the handle may be very loud without a brush head.

Also, as brush heads wear out, they may start to produce more noise. A noisy handle may indicate that it is time to replace your brush head.

Finally, counterfeit brush heads may make a lot of noise when used on your Sonicare handle. We recommend that you only use genuine Philips Sonicare brush heads with your Sonicare toothbrush.

In all of these cases, this change in sound does not adversely affect the device's performance. To fix the problem, place a new, genuine brush head on your handle and turn it on. This should alleviate the noise. If not, please call the Philips Call Center.
