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.
