-
Sonicare toothbrushes use powerful vibrations to clean your teeth. The sound produced is louder than a manual toothbrush. If this is your first electric toothbrush, it can take a while to get used to electric brushing.
-
If you turn on your toothbrush without a brush head, it will make more noise. Always ensure that a brush head is attached to your toothbrush.
-
If your toothbrush makes an abnormally loud noise, a loose brush head may be the reason. Ensure the brush head is firmly placed on the handle and not loose. A small gap will remain between the handle and brush head as needed for vibration.
-
It could also mean that your brush head is worn. We recommend replacing your brush head every three months. You can purchase a new brush head in our online store. -
Try the following steps:
Step 1: Remove the brush head from the handle.
Step 2: Turn your toothbrush on.
Is your toothbrush still making a loud or abnormal noise?- Yes: your toothbrush is broken. We recommend you request an online repair or exchange.
- No: if the noise stops, your brush head is defective or worn out. You need to replace your brush head with a new one.
-
If none of these tips help, your toothbrush may be damaged internally. We recommend that you request a repair or exchange for your toothbrush.
