What is bruxism?

Bruxism is the habitual clenching or grinding of the teeth. Both children and adults do it, usually when they feel stressed or tense. Most people do it at some time in their lives, and it is usually mild enough not to be a problem with insomnia, jaw alignment or noticeable wearing down of teeth.

Bruxism is an unconscious habit that can occur during the day or at night (sleep bruxism), or even during a short nap. It is bruxism whilst sleeping that causes most health problems.

Bruxism can occur when the teeth touch for a fraction of a second (similar to chewing) or when the teeth touch for several seconds (clenching).

Most bruxers are not aware that they are grinding their teeth. Usually a sleeping partner or parent will notice the bruxism before the person bruxing is aware of it. Bruxism can be loud enough to wake a sleeping partner. A dentist may alert a patient to bruxism during a visit, when the damage to teeth is visible.

Symptoms of bruxism

• Dental damage will usually occur over time, wearing down the teeth, loosening the teeth, and risking tooth loss and gum recession.
• Pain in the jaw's joints or jaw muscles, or the teeth involved (toothache / tooth pain).
• Headaches.
• Sore and sensitive teeth.
• Muscle tension throughout the day.
• Migraines triggered by clenching.
• Neck pain and stiffness.
• Depression, anxiety, chronic stress and tension leading to cardiovascular problems. (3)
• Earache.
• Eating disorders.
• Insomnia.
• Tinnitus.

Causes of bruxism

1. Muscle dysfunction. Bruxism is caused by a muscle dysfunction in which there is involuntary muscle movement. (10)

2. Serotonin and dopamine. This muscle dysfunction is caused by low levels of the feel good hormones serotonin and dopamine. (4, 6)

3. Vitamins B1 and D deficiency. Low levels of serotonin and dopamine are caused by stress, vitamin B1 (thiamine) (8) deficiency, and vitamin D deficiency (5, 7, 11).

Factors causing the above include:

• Extended high stress or trauma.
• SSRI pharmaceuticals. (2)
• Smoking.
• Alcohol.
• Caffeine excess.
• Family history of bruxism. (9)
• Poor bite alignment.
• Certain medical conditions and ailments including digestive problems, sleep apnoea (9) and allergic reactions.
• Drug use, including alcohol, smoking, amphetamines and related stimulants.
• Obsessive-compulsive disorder.
• Disorders such as Huntington's and Parkinson's diseases.

Treatment and remedies for bruxism

If diagnosed early (before it becomes habitual), finding and eliminating the original cause(s) may cure bruxism. Once bruxism becomes habitual, it should also be treated with habit-modification (1) such as biofeedback.

Your dentist can provide a custom-made dental guard. It should fit perfectly and be comfortable to wear while sleeping. If the dentist is too expensive, you can also buy a dental guard in many stores. You put them in hot water to make them soft enough to fit, and when they cool they stay in that shape. Dental guards prevent further damage to the teeth and unnecessary wearing.

• Vitamin B1 (thiamine) sufficiency. The best source of B vitamins is nutritional yeast. Food sources include home made milk kefir, sunflower seeds, meat, fish and real unprocessed foods.
• Vitamin D and getting outside into nature and sunlight.
• Stress and anxiety management.
• Eliminate or reduce alcohol, smoking, amphetamines and related stimulants, caffeine from coffee in excess of a couple of cups per day, black tea in excess of several cups per day.
