Since the flu is a viral infection, antibodies are developed once you have been infected, which helps prevent you from catching the same illness twice. Even for bacterial infections or minor illnesses like the common cold, the likelihood of becoming re-infected from your toothbrush is fairly slim. Also, toothpaste frequently contains antibacterial compounds, which further decrease the chances of becoming re-infected.
The American Dental Association recommends the following tips for toothbrush care:
- Do not share toothbrushes, especially if you are sick.
- Allow the brush to air dry after each use.
- Store the toothbrush in an upright position to allow water to drain and dry faster.
- Replace your toothbrush every 3-4 months. Worn bristles are less effective in properly cleaning your teeth, and can actually be damaging to teeth if used too long!
