How Often Should You Change Your Toothbrush?

Maintaining proper oral hygiene not only includes flossing, brushing daily, and regular dental checkups, but also making sure you change your toothbrush on a regular basis. There are a variety of factors that go into the deterioration of a toothbrush. As a rule of thumb, you should change your toothbrush every 3 to 4 months. However, if your toothbrush falls into the following categories it should be replaced sooner.

Here are tips to know how often you should change your toothbrush

Change your toothbrush after general wear and tear

As mentioned, it’s recommended that you change your toothbrush every 3 to 4 months. However, how often you change your toothbrush varies depending on the style of your toothbrush. For example if you own an electric toothbrush that is made to last, you probably won’t follow the same replacement schedule as a manual toothbrush. Stocking up on replacement toothbrushes to keep in your home will ensure that you regularly change your toothbrush and that you have a clean toothbrush on hand once your current one wears out.

Change your toothbrush after illness

Another sign you should change your toothbrush is if you’ve recently been sick. If you’re sick, excess bacteria may linger on the toothbrush as it dries, making the spread of germs more likely. Not only could this prolong your illness, it could get members of your family sick as well. To reduce the spread of germs you should replace your toothbrush after your illness. However, if you recently changed your toothbrush or use an electric toothbrush, you should thoroughly sanitize your toothbrush to ensure that you prevent the spread of germs.

Change your toothbrush after travel

It’s also recommended that you change your toothbrush after travel. Especially if the toothbrush has been contaminated in your travel bag. Using protective plastic cases can help you avoid the increase of bacteria. However, it’s recommended that you let your toothbrush dry completely before placing it in a protective case. Without giving your toothbrush time to dry during travel, it increases the amount of bacteria on the bristles, which could lead to illness.

Change your toothbrush after a cleaning

Typically when you visit the dentist’s office, you will be provided a new toothbrush after your cleaning. In order to start fresh after a cleaning, it’s a good time to replace your toothbrush. The new toothbrush will prevent you from reintroducing the bacteria left on your current toothbrush to your freshly cleaned teeth.


Overall, you need to change your toothbrush regularly to maintain your oral health. By following these general rules of thumb you can be sure that your toothbrush remains fresh. Changing your toothbrush regularly prevents tooth decay and illness from built up bacteria left on your bristles.
