Teeth grinding

Teeth grinding, or bruxism, can affect your jaw, cause pain, and even change the appearance of your face.

"People who have otherwise healthy teeth and gums can clench so often and so hard that over time, they wear away their tooth's enamel, causing chipping and sensitivity," says Halpern.

Stress and anger can increase nighttime teeth grinding. "Finding ways to alleviate these feelings can help, but it's also important to see your dentist, who can recommend solutions like a custom night guard," advises Perle.
