Many people grind or clench their teeth without realizing it, often while they sleep. This habit, called bruxism, might seem harmless, but over time it can wear down teeth, cause jaw pain, and even lead to cracked teeth or broken fillings. Recognizing teeth grinding early can save you from costly repairs later.

Signs you might be grinding

• Waking up with a sore jaw, tight facial muscles, or a dull headache near the temples
• Teeth that look flattened, chipped, or shorter than they used to
• Increased tooth sensitivity
• Clicking, popping, or pain in the jaw joint
• A partner who hears grinding sounds at night
• Scalloped marks along the sides of your tongue or ridges inside your cheeks

What causes bruxism?

There is rarely a single cause. Common contributors include stress and anxiety, sleep disorders such as sleep apnea, caffeine and alcohol, certain medications, and a bite that does not line up well. Daytime clenching often happens during concentration, like driving or working at a computer.

How a night guard helps

A night guard is a thin, custom-made appliance worn over your teeth while you sleep. It does not always stop the grinding itself, but it places a protective cushion between your upper and lower teeth so the guard takes the wear instead of your enamel. Many patients also notice less jaw soreness and fewer morning headaches.

Over-the-counter guards are available, but a custom guard from your dentist fits precisely, is more comfortable, and is less likely to shift or change your bite.

Other ways to ease grinding

• Manage stress with exercise, stretching, or a relaxing bedtime routine.
• Cut back on caffeine in the afternoon and limit alcohol in the evening.
• Notice daytime clenching. Try to keep your lips together and teeth slightly apart when relaxed.
• Avoid chewing on pens, ice, or gum all day, which trains the jaw muscles to stay tense.
• Ask about sleep quality. If you snore or wake up tired, a sleep evaluation may be worthwhile.

Teeth grinding and tooth sensitivity

Teeth grinding often goes hand in hand with sensitivity, because worn enamel exposes the layer underneath. Our post on sensitive teeth causes and relief covers what you can do at home.
