Can electric toothbrushes damage enamel or gums?

When used correctly, no. In fact, many electric toothbrushes are gentler than manual brushing because they include pressure sensors that alert you when you are pushing too hard. Aggressive manual brushing is a leading cause of enamel wear and gum recession. If you have sensitive teeth or gums, look for a brush with a dedicated sensitive mode and a pressure sensor both features are available at every price point in our list.
