Koreans brush their teeth more any place we have been. Students and teachers line up and are brushing away after lunch. They follow the three- three's rule: You must brush :
- 3 times a day
- for 3 minutes
- within 3 minutes of eating
As a kid I remember being taught "brush after every meal", but I could not remember for how long, so I checked at the American Dental Association site. Best I could tell, the ADA is messing with me because they changed the rules without informing me. It now recommends brushing twice a day...no recommendation on the length of time. Strange. The British Dental Association (insert joke here) recommends brushing for two minutes.
