Electric toothbrushes can be gentler on the gums as some models alert you if you brush too hard. With proper use of an electric toothbrush, many people prefer it over a manual toothbrush. However, as long as it's clean enough after using a manual toothbrush, this is good enough, so you don't necessarily have to switch to an electric toothbrush. A clean tooth will not get a cavity. During an examination, we guide and instruct on brushing technique and recommend an electric toothbrush if necessary.
