The grossest thing in your bathroom? Not your toilet. Not the plunger. Not the toliet brush...It's our toothbrush!

Yahoo! has given us some tips on how to cut down on the bacteria on your toothbrush:

Don't share toothbrushes and store different family members' toothbrushes at least an inch apart.

Rinse thoroughly after using.

Allow toothbrush to air dry after each use, preferably in an upright position. This will keep bacteria from breeding. Don't store in a small, moist, closed container.

Replace your toothbrush after having a cold or the flu.

Get a new toothbrush every 3 to 4 months or more frequently if you notice the bristles breaking down. While this won't reduce bacteria, it will ensure the best cleaning power.
