When’s the last time you replaced your toothbrush? If you can’t remember that’s probably not the best sign. Many people end up using the same toothbrush for far longer than they should. At Edgewater Dental Arts, we’re not here to judge but we do want to make sure you’re practicing healthy dental care habits to keep your teeth and gums as protected as possible. Here’s the scoop on when to replace your toothbrush:

A Toothbrush’s Lifespan

So, the answer you’ve been waiting for—you should be replacing your toothbrush every three to four months. Perhaps that’s a far shorter time than you were expecting, but that’s the official recommendation from the American Dental Association. This applies to both manual toothbrushes as well as electric toothbrush heads.

Reason for Replacement

The reason you should be replacing your toothbrush within this timeframe is because that’s around when the bristles start to fray. When you use a worn-out brush with frayed bristles, it’s not as effective. You may be keeping with your twice-a-day brushing, but it won’t be producing the same kind of clean as an unfrayed toothbrush. If you’re not sure when you first got your toothbrush, you can also have a look and see if the bristles looked frayed and that’s all the information you need to know.

An Exception with Illness

If you’ve been sick with a cold or flu, don’t wait for the three or four month-period to get a new toothbrush. Replace it when you’re getting better so that you don’t end up re-infecting yourself or others with whatever germs might still be hiding there.
