Teeth grinding, or bruxism, can affect your jaw, cause pain, and even change the appearance of your face.
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.
Contrary to what mom said, sugar won't directly rot your teeth—but the acid produced when you eat sugar and carbohydrates can. Naturally occurring bacteria in the mouth devour sugar, creating acids that attack tooth enamel, which can lead to decay and a host of other problems, including gingivitis and cavities.
The worst thing you can do is leave sugar lingering on your teeth and gums. Eating any amount of candy and brushing and flossing immediately is actually less damaging than not brushing after eating one piece before bedtime.
A dry mouth isn't just unpleasant, it's bad for your teeth. Saliva washes away cavity-causing bacteria and neutralizes harmful acids.
Drink lots of water, chew sugarless gum, use a fluoride toothpaste or rinse, and consider over-the-counter artificial saliva substitutes. See your doctor if it's a frequent problem.
