How to Repair a Sonicare Toothbrush

Updated February 21, 2017

Sonicare makes five styles of electric toothbrushes: Advance, Elite, Essence, FlexCare and FlexCare with Sanitizer. Electric toothbrushes are quite a bit pricier than manual or battery operated toothbrushes, so if your Sonicare electric toothbrush stops working, naturally you may be hesitant to replace it before trying to repair it, especially if you have only owned it for a short time. You can repair the toothbrush yourself. Sonicare owners' manuals provide helpful tips to troubleshoot and repair your brush, and the models all operate in a similar fashion.

Charge your Sonicare toothbrush. The brush comes only partially charged, so the charge may not last long. Recharge the toothbrush overnight by setting the base in the charger included with the brush. Plug the charger into an electrical socket not controlled by a light switch. If the toothbrush emits a series of beeps, it means you only have a few minutes of charge left in the brush.

Clean your Sonicare toothbrush head if the brush seems to be losing power. If the power gets too low, order a new brush head from Sonicare. Follow the instructions in the owner's manual to replace the head on your model of Sonicare toothbrush.

Tighten the cuff holding the brush head to the handle of your Sonicare brush if the brush head rattles when you brush your teeth. See owner's manual instructions for your model of brush. If the rattling continues, replace the brush head.

Stop your Sonicare brush from making a loud noise by removing the clear plastic travel cap provided for the brush head. Always remove this before you turn the brush on. Also tighten the cuff holding the brush head to the handle to prevent loud noises.

Eliminate odour from your Sonicare electric toothbrush by thoroughly cleaning the brush per the instructions in the owner's manual for your model of brush. If the odour persists, replace the brush head.


Clean your brush head and handle after each use to keep it in top operating condition. Replace the brush head every six months or when the bristles begin to bend or break.


Do not place the charger where it could fall into a sink or tub. If it does fall into water, unplug the toothbrush from the electrical socket before reaching into the water to get it or you could be electrocuted. Supervise a child who uses a Sonicare electric toothbrush.
