Most dentists don’t go a day without seeing patients who are damaging their teeth and gums by brushing too hard. Some report that as many as two out of three patients brush their teeth too hard. This is a problem. A stiff-bristled toothbrush combined with overzealous brushing teeth can cause serious dental problems over time, including gum disease and tooth sensitivity.
People think that if they brush twice as hard, they will do twice as much good, In fact, overzealous brushing can cause significant damage to the periodontal tissues and bones that support the teeth.
