Why do we need to brush our teeth?

Brushing removes food and plaque, which is a transparent sticky substance, from the surface of teeth. The removal is important due to bacteria found within plaque. If allowed to remain on the teeth, bacteria begin to attack and break down tooth enamel, which can lead to cavities and tooth decay.

The American Dental Association recommends a daily regimen that includes brushing at least twice per day, flossing at least once per day and eating healthy foods. The ADA also recommends regular dental checkups and getting a new toothbrush every three to four months. The association advises against eating too many snacks, especially foods and beverages loaded with sugar.
