You would be very surprise to learn the more than half of the American population only brush their teeth once a day. In fact, 49% of men and 57% of women brush their teeth only once a day. Even if you are the other half that actually brushes their teeth twice a day sources say they still are doing something wrong. Everyone is suppose to brush their teeth twice a day for 2 whole minutes. Dentists say that you are supposed to brush your teeth for a whole 2 min in a circular motion to avoid plaque, gum disease, and cavities.
