When should you replace your toothbrush?

How often should we replace our toothbrushes?

Question:

Assuming that you brush two times each day, you should get a new toothbrush every three months. Young children often chew on their brushes and therefore, they may need to be replaced more often.

Interestingly, a study financed by Colgate-Palmolive found that only about nine percent of consumers regularly replace their toothbrushes! Most Americans replace their brushes once every nine months. In Japan, toothbrushes are replaced every 3 months, on average.

A worn toothbrush is less effective at removing plaque and can harbor disease-causing bacteria and viruses between the damaged bristles.

Be sure the toothbrush has soft bristles and is approved by the American Dental Association (ADA). Hard, worn or frayed bristles can damage the gum tissue!
