The American Dental Association recommends getting a new toothbrush every three months in order to avoid brushing your teeth with bristles that may contain bacteria. If you are using an electric toothbrush then you need to change the head every three months as well. With every scheduled cleaning Sachem Dental gives you a new toothbrush to replace your old one, as well as some sample toothpaste and floss.
Some people can use their toothbrush repeatedly until they misplace it. The average American only change their brushes 1.9 times a year. The American Dental Association recommends that you change your toothbrush at least four times a year, approximately 3 months and every time you are sick. If the bristles of your toothbrush start flaring before three to four months, then you are using too much pressure to brush your teeth. Dentist believes toothbrushes should be thrown out after roughly 40 to 50 uses. Healthy people should change brushes every two weeks.
