Sniffle Solutions

Probably not. Although cold and flu germs can live outside of the body for up to two days, chances are your child won’t re-infect himself. That’s because when you get sick, your body develops antibodies to fight off that specific virus strain. If you want to play it safe, soak your child’s toothbrush in a bleach solution (one part bleach to nine parts water) for 10 to 15 minutes to sterilize it. Then, make sure to rinse it thoroughly and let it dry.

But if your child suffered from a bacterial infection, such as strep throat, it’s best to toss out that brush. Bacteria can colonize in the brush, and your child may be vulnerable after she finished her course of antibiotics.

Of course, it’s important remind your kids not to share toothbrushes and cups, especially during and after a cold. And dental experts remind us that we should always replace them every three months, when the bristles start to fray and aren’t as effective at removing plaque.
