Change your toothbrush or the replacement head on your electric or battery-powered toothbrush at least every three to four months.

Change it sooner if it becomes frayed.


Keeping a toothbrush for too long makes it difficult to clean your teeth well, and it may contribute to bad breath or other oral health problems.
