The Use and Handling of Toothbrushes

We all know that brushing with fluoride toothpaste is the most recommended and most used method of caring for our teeth. When we do this, we are removing plaque build-up, and in turn reducing bacteria associated with gum disease and tooth decay.

When we brush our toothbrushes become contaminated with the bacteria found in our mouth. Here are some recommended toothbrush care tips:

• Do not share toothbrushes. The exchange of body fluids that such sharing would foster places toothbrush sharers at an increased risk for infections.
• After brushing, rinse your toothbrush thoroughly with tap water to ensure the removal of toothpaste and debris, allow it to air-dry, and store it in an upright position. If multiple brushes are stored in the same holder, do not allow them to contact each other.
• It is not necessary to soak toothbrushes in disinfecting solutions or mouthwash. This practice actually may lead to cross-contamination of toothbrushes if the same disinfectant solution is used over a period of time or by multiple users.
• It is also unnecessary to use dishwashers, microwaves, or ultraviolet devices to disinfect toothbrushes. These measures may damage the toothbrush.
• Do not routinely cover toothbrushes or store them in closed containers. Such conditions (a humid environment) are more conducive to bacterial growth than the open air.
• Replace your toothbrush every 3-4 months, or sooner if the bristles appear worn or splayed. This recommendation of the American Dental Association is based on the expected wear of the toothbrush and its subsequent loss of mechanical effectiveness, not on its bacterial contamination.
