  If your P&G Electric Toothbrush isn't charging, it could be due to several reasons. The battery might be at a very low charge level, requiring at least 30 minutes to show any charging activity. The ambient temperature could be outside the valid charging range (less than 0°C or greater than 40°C); a temperature between 5°C and 35°C is recommended. Also, ensure the charger is properly connected to a mains voltage outlet.

  If your P&G Electric Toothbrush handle isn't working with the Oral-B App, here are a few things to check: First, make sure the Oral-B App is open. Then, verify that Bluetooth is enabled on your smartphone. Also, ensure Bluetooth is enabled on the toothbrush handle by pressing the ON/OFF button for 5 seconds. If the connection was lost, try pairing the handle and smartphone again through the app settings, keeping your smartphone nearby.

  If your P&G Electric Toothbrush is making a rattling or loud noise, it might be because the brush head isn't correctly placed on the handle. Check the fit; a small gap will remain. Alternatively, the brush head may be worn and need replacement.
