Ask the Dentist: Brushing Duration
Expert answers to your questions about dental care.
Q: How long should I brush?
A: "Let me put it this way," says Edward G. Kaufman, dean of New York University's College of Dentistry. "After you finish brushing and think your teeth are clean, start all over again."
The Academy of General Dentistry in Chicago says most people rush through brushing. Although we think we may be brushing for three to four minutes, most of us don't even last one minute.
A helpful hint: Turn on the radio and brush for the duration of a song.
