When should you replace your toothbrush?
Updated On: Nov 19 2013 03:21:18 PM CST
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.
