Electric toothbrushes are able to clean at up to 30,000 strokes per minute compared to manual brushes that can only produce up to 200 strokes. The more strokes, the more plaque removed, the better. This fact can be a pretty convincing one if you are on the fence about the usefulness of an electric toothbrush.
In addition, electric toothbrushes can reduce 21% more plaque and 11% more gingivitis after three months of use. Plus, many electric toothbrushes have a 2-minute timer built-in to let you know when you have brushed your teeth for long enough.
Electric toothbrushes help to stimulate the blood flow in your gums, which helps keep them healthy and less likely to bleed or become swollen after brushing or flossing.
