Components inside an electric toothbrush charger typically are sealed from entry, so if it goes bad you must replace the entire unit.

What Can Go Wrong with an Electric Toothbrush?

Problems usually involve either the brush
heads, which are easily replaced if worn or faulty, or the charger. The power handle is typically sealed to prevent shock, so internal repairs should be left to a professional.

Who can repair your sealed electric toothbrush? Because they are small motorized electric appliances, nearly any small appliance repair shop can do it. Make sure you clean the unit well before delivering it to the repair person. Also be sure it’s worth the cost of repairs. It might be more cost effective to just buy a new one.

How Can I Identify an Electric Toothbrush Problem?

  • If the appliance doesn’t work at all, make sure the power is on at the outlet, then test the electrical cord and battery recharger with a multimeter and replace the cord or charger if needed.
  • If the unit still doesn’t work, clean the charger post. If the charger shocks the user, have it professionally serviced or replace it.
