A new clue about bruxism.

A neurology practice noted that of its patients who had restless legs syndrome (RLS), 60% also had bruxism (grinding teeth during sleep). Eighty-three percent had RLS and migraines, and 52% had RLS, migraines, and bruxism.

Do you relate?

The lead neurologist for this study speculated there is a gene that links these conditions.

It gets more interesting. Both restless legs syndrome and bruxism are involuntary movements occurring during sleep. Is bruxism “restless jaw syndrome?”

I’m always happy to see more research about TMJ-related issues, especially because there are so many factors that play a role in jaw dysfunction and pain.

This may be something to show your doctor, or you may be interested in taking a supplement or adding foods to your diet that help your body produce more dopamine (more info below).

More about bruxism.

Bruxism includes clenching and grinding the teeth. Some distinguish these as “waking bruxism” and “sleep bruxism”.

They may have different causes, in my opinion.

Sleep bruxism, in contrast to daytime clenching, is hard to treat because it occurs when you’re unaware of your behavior and unable to change it.

Waking bruxism is a habit that can change with awareness and practice. I’ve helped many clenchers learn how to relax their mouth position.

Some things I’ve noted about bruxism in my manual therapy practice:

  • Many people don’t know they grind during sleep until a dentist tells them they have damaged teeth.
  • Sometimes the noise of grinding during sleep is loud enough to wake up family members, and that’s how people learn they have sleep bruxism.
  • People who grind at night often wake up with jaw, face, or neck pain, earaches, and/or headaches.
  • Bruxism often results in the need for expensive dental work: mouthguards or splints to prevent further damage and crowns to fortify cracked or broken teeth.
  • Over time, bruxism can damage the temporomandibular joints, possibly requiring surgery.

Dentists and jaw issues.

Many people expect dentists to be experts on jaw issues, yet their domain is treating the teeth and gums.

Learning about TMJ disorders is not required in dental school.

General practice dentists can prevent further tooth damage with appliances like mouthguards and splints. They can repair existing tooth damage or replace teeth with implants.

Some dentists may try to adjust the positioning of the TMJs, and a few dentists also address airway issues (like sleep apnea, which may accompany sleep bruxism) in their work.

Dentists do not address stress or tension in the jaw muscles, which contribute so much to jaw pain. Any overworked muscle will hurt, tighten, and perhaps spasm. The jaw muscles are no different.

Some dentists and hygienists in the Austin area refer people with jaw pain or issues opening wide to me for TMJ relief bodywork, including intraoral work on internal jaw muscles.

Solutions to try.

If you grind your teeth during sleep, it is possible to stop by using hypnotherapy and EFT.

I often recommend a recorded hypnotherapy session for bruxism that’s available on YouTube to listen to before sleep.

I don’t know if it works for everyone, but it’s soothing — I always fall asleep before it ends. Less stress is always desirable.

I’ve also heard that starting a regular meditation practice can over time reduce or stop bruxism completely. There are many types of meditation. If you don’t have a good teacher, I recommend Mindfulness-Based Stress Reduction taught online by Jon Kabat-Zinn.

As mentioned above, dopamine agonists are prescribed for low dopamine levels.

Dopamine is released when your brain is expecting a reward — when you anticipate a pleasurable activity such as eating a delicious meal, spending time with someone you love, or receiving a big check.

It’s sometimes called “the happy hormone” because it affects your enthusiasm, motivation, and focus.

If you suffer from bruxism, before going the pharmaceutical route with dopamine agonist drugs, you may want to consider nutrition — consuming foods or taking supplements that raise your dopamine levels.

In particular the amino acid tyrosine increases dopamine.

  1. Thank you! Having experienced both for most of my life, I felt resigned. But this is hopeful information, and helpful too.
