Since the flu is a viral infection, you develop antibodies once you’ve been infected. This helps prevent you from catching the same illness twice. Even for bacterial infections, the likelihood of becoming re-infected from your toothbrush is fairly slim for minor illnesses like the common cold. Also, toothpaste frequently contains antibacterial compounds, which further decreases your chances of re-infection.
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!
