Brushing your teeth, flossing, and using mouthwash are all essential for a good oral hygiene routine. But one part that many people overlook is how often toothbrushes should be changed. Over time, bacteria build up on toothbrushes, so they need replaced periodically. Here, family dentistry provider, Aina Haina Dental Group in Honolulu, HI, explains what you need to know.

Replacing Your Toothbrush

The general rule of thumb is to replace your toothbrush every 3 months. You may need to replace it sooner if the bristles have become frayed—brushes are less effective at cleaning plaque when they wear out—or have a lot of toothpaste or saliva built up on them, which will house bacteria. Keep an extra pack of brushes in your home for convenience. You’ll also typically get a replacement brush and toothpaste at an annual dental cleaning with your family dentistry office twice a year. 

Consider Your Overall Health

If you're recovering from illness, replace your toothbrush once you're feeling better. Germs and bacteria will have accumulated on the brush while you were ill, so continuing to use it may make you sick again.

Maintaining Your Toothbrush

In between replacements, take steps to ensure your brush remains clean. Rinse it with warm water after each use to remove all toothpaste residue. Let it air dry in an open container, such as a cup, where it can stand up straight and the bristles aren't touching other bathroom products.
