Use Philips brush heads
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.
Counterfeit brush heads may make a lot of noise when used on your Sonicare handle. We recommend you only use genuine Philips Sonicare brush heads with your Sonicare toothbrush.
Replace your brush head
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.
