Toothbrushes & Infection
A toothbrush is necessary for good dental health and hygiene. But improper handling of toothbrushes may lead to a greater risk of infection. The American Dental Association, or ADA, has guidelines to follow for reducing the spread of infection via toothbrushes.

Toothbrush Replacement
-
The ADA recommends replacing your toothbrush every three to four months. Buy a new toothbrush sooner if your old one develops frayed bristles. To avoid a recurrence of infection, replace your toothbrush after illness.
Toothbrush Use
-
Always use your own toothbrush. Sharing toothbrushes can lead to the spread of bacteria and viruses.
-
Toothbrush Storage
-
Store your toothbrush upright if you can. Never cover your toothbrush for storage. If you store several toothbrushes together, do not allow the bristles to touch, to minimize the spread of infection.
Toothbrush Cleaning
-
Rinse your toothbrush with tap water after using it. The ADA says that is sufficient. You do not need to disinfect your toothbrush by soaking it in any type of solution or running it through the dishwasher.
Other Considerations
-
Use an antibacterial mouthwash before brushing your teeth to decrease the amount of bacteria in your mouth and therefore the amount that ends up on your toothbrush, the ADA suggests. Households with immune-compromised people may also consider using disposable toothbrushes to cut down on the spread of infection.
