Every 3-4 months: The american dental association recommends throwing out your toothbrush every three to four months. If the bristles become frayed, you're sick, or you have a weak immune system, throw it out even more often. If you use an electric toothbrush, throw out the head as often as you'd discard a disposable toothbrush.

Every 5 or 6 months: You should replace your toothbrush every 5 or 6 months, or after you have been sick.

New tooth brush: Replace your tooth brush when it begins to look worn and frayed. This varies depending upon the individual tooth brush, how often you brush, for how long and with how much pressure. Some toothbrushes have indicators to help you determine that. Generally every one to three months or after a cold, the flu, a sore throat or any oral infection.

Every three months: The dentist always gives you a new one at the prophylaxis visit.
