According to the American Dental Association, individuals should be brushing their teeth for at least two minutes at a time. In some cases, people can benefit from brushing for three minutes if they’re more vulnerable to decay and gum disease. However, you shouldn’t be brushing any longer than that, as doing so does not work to remove more plaque.
Additionally, brushing for too hard can lead to problems that permanently damage your teeth and gums, according to a dentist in Ocala.
