How Often Should You Replace Your Toothbrush?


We all know the importance of brushing every day to keep our teeth healthy, and since we use this simple device every single day, it’s also important to make sure we’re using a toothbrush that’s clean and in good shape. Because of that, the American Dental Association recommends replacing your toothbrush every three to four months, or as soon as the bristles become frayed from brushing. Here are some other tips on keeping your brush clean:

Don’t share your toothbrushtoothbrushes
More than one person using a toothbrush could result in an exchange of microorganisms between the users, thereby increasing your risk for infection. This is especially dangerous among people with compromised immune systems or existing infectious diseases.

Thoroughly rinse your toothbrush after brushing
Once you’re done brushing, it’s important to thoroughly rinse off any remaining toothpaste and the bacteria that you just removed from your teeth. After that, store the brush upright and allow it to air-dry. If more than one brush is stored in the same holder keep the brushes separated.

Do not routinely cover toothbrushes or store them in closed containers
A moist environment such as a closed container is more conducive to the growth of microorganisms than the open air. This is especially important when you’re traveling, and keep your brush in a carry case. Once you’ve reached your destination, pull the toothbrush out of the case and set it upright to dry.

Replace toothbrushes at least every 3–4 months
After this point, the bristles are too worn out to be very effective, and if you tend to brush harder, the bristles may wear out faster. To gauge whether or not you’re brushing too hard, try brushing with you nondominant hand. That should be the amount of pressure you apply when brushing regularly.

Regular brushing and flossing habits are your best defense against cavities and gum disease. If you have questions about brushing or teaching your children how to brush properly, talk to your Arizona dentist.
