Bruxism and Mental Health
Grinding or clenching your teeth? It's often your body's way of expressing stress you can't release.
What Is Bruxism?
Bruxism is the involuntary grinding, clenching, or gnashing of teeth, often occurring during sleep but also when awake.
It affects 8-31% of the population and is strongly linked to stress, anxiety, and mental health conditions.
Many people are unaware they have bruxism until a dentist notices wear on their teeth or a partner hears grinding at night.
While it's a physical condition, its roots are often deeply psychological.
Signs of Bruxism
Jaw pain, stiffness, or clicking upon waking.
Headaches, particularly in the temples.
Worn, chipped, or sensitive teeth.
Partner reporting grinding sounds during the night.
Facial pain or earache without obvious cause.
Tight jaw muscles or difficulty opening your mouth wide.
Disrupted sleep, even if you don't remember grinding.
The Mental Health Connection
Stress and anxiety are the strongest risk factors for bruxism.
It often worsens during periods of high stress or emotional difficulty.
Suppressed anger or frustration may literally manifest as jaw clenching.
ADHD medications and some antidepressants can increase bruxism.
Sleep disorders and bruxism frequently co-occur.
Management Strategies
See a dentist for a custom mouthguard to protect your teeth.
Address underlying stress and anxiety through therapy or self-help.
Practice jaw relaxation exercises throughout the day.
Avoid chewing gum, which can reinforce clenching patterns.
Reduce caffeine and alcohol, which can worsen bruxism.
Mindfulness and body scan meditations can help release jaw tension.
If medication-related, discuss alternatives with your prescriber.
