A Friendly Smile

A Friendly Smile

Here’s a new prescription for keeping your smile healthy: brushing, flossing, and socializing regularly. In a recent study, people who had at least one close friend appeared to have as much as a 30 percent lower risk of periodontitis, a dental disorder that can lead to tooth loss. Researchers speculate that the connection may be due to the stress-reduction benefits that friends offer; stress is associated with poor oral hygiene.
