Need some incentive to take better care of your teeth? People who are really diligent about brushing and flossing are probably safe skipping dentist visits -- going every year or two instead of every six months.

First-aid guides often tell us to transport a tooth to the dentist in milk -- or better yet, tucked under your tongue where it can stay covered in saliva. But it's OK to put the tooth back in its socket, and in fact, that's what dentists recommend.
