Is brushing three times a day too much (over brushing)?
Well, I have a friend who brushes after every meal, and I think that's excessive. But I wasn't sure how much is too much.
According to American Dental Association, it's recommended to brush at least twice a day for two minutes each time, using a fluoride toothpaste. Brushing excessively can cause abrasion of tooth enamel, which can lead to tooth sensitivity or even decay. Do you have any other questions?
