One Tech Tip: How to repair an electric toothbrush

Toothbrushes used to be simple, powered only by your hand so they never broke down. Rechargeable electric toothbrushes are increasingly popular because they make brushing easier and more effective, but they're a headache when they stop working properly. The batteries are usually rechargeable but don’t last forever. The question of their longevity, and toothbrush repairability as a whole, is the subject of many online forums. You can pay someone else to repair it, or — with some online help — do it yourself. You'll need to remove the bottom cap and slide out the electronic innards to get to the battery.
