Teeth Grinding (Bruxism): Causes, Symptoms and How to Protect Your Teeth
Do you wake up with a sore jaw, a dull headache, or teeth that feel sensitive? You might be grinding or clenching your teeth, a condition called bruxism. Many people do it in their sleep and have no idea until a partner hears it or a dentist spots the signs.
Left untreated, teeth grinding can wear down enamel, crack teeth, and strain your jaw. Here is what causes it, how to recognize it, and what you can do.
What Is Bruxism?
Bruxism is the habit of grinding, gnashing, or clenching your teeth. It can happen:
- While awake: often clenching during stress, concentration, or screen time.
- While asleep: sleep bruxism, which is harder to control and often goes unnoticed.
Common Causes of Teeth Grinding
- Stress and anxiety
- Sleep disorders such as sleep apnea or snoring
- Caffeine, alcohol, and tobacco use
- Certain medications, including some antidepressants
- A misaligned bite or missing teeth
- In children, growth and new teeth coming in (many kids outgrow it)
Signs and Symptoms of Teeth Grinding
- Jaw pain, tightness, or fatigue, especially in the morning
- Dull headaches starting at the temples
- Flattened, chipped, or cracked teeth
- Worn enamel and increased tooth sensitivity
- Earache-like pain without an ear infection
- Clicking or popping in the jaw joint (TMJ)
- A grinding noise at night that others notice
- Bite marks on the inside of your cheek
Why Teeth Grinding Is a Problem
The forces from grinding are much stronger than normal chewing. Over time, bruxism can wear teeth down, crack fillings and crowns, lead to root canal treatment or even tooth loss, and contribute to jaw joint problems. Catching it early protects your teeth and saves you from bigger repairs later.
How to Stop Teeth Grinding
Custom Night Guard
A custom-fitted night guard is one of the most effective ways to protect your teeth. It creates a cushion between the upper and lower teeth so the guard takes the wear instead of your enamel. Custom guards fit better and are more comfortable than store-bought versions.
Manage Stress
Exercise, deep breathing, stretching, and a relaxing bedtime routine can reduce grinding linked to stress.
Cut Back on Stimulants
Limit caffeine in the afternoon and evening, and reduce alcohol and tobacco.
Notice Daytime Clenching
Remind yourself: “lips together, teeth apart.” Your teeth should only touch when you chew or swallow.
Treat the Underlying Cause
If your dentist suspects sleep apnea, a bite issue, or medication side effects, they may recommend further evaluation or treatment.

There is no single cure, but it can be managed well. A night guard protects your teeth while you address causes like stress or sleep issues.
Is teeth grinding common in children?
Yes. Many children grind their teeth and outgrow it. Mention it to your dentist so they can monitor for wear.
Are store-bought night guards okay?
