How to deal with teeth grinding and jaw clenching

Also known as bruxism

Bruxism is the involuntary, non-functional, and forceful clenching, grinding, or rubbing of teeth which often occurs in sleep. Millions suffer from this condition, and many might not be aware of it until their dentist advises them of it. In fact, recent estimates show that up to 25% of children and 30% of adults suffer from it [1, 2].

Bruxism causes a variety of problems

Evidence suggests that patients with bruxism are prone to:

How to reduce the grinding and its damage

Reduce stress, smoking, insomnia

Bruxism is associated with stress, cigarette smoking, and insomnia, so reducing stress, treating underlying anxiety issues, stopping smoking, and practicing good sleep hygiene helps. But often this isn’t enough to fully treat the problem.

Wear a night guard to bed

An oral night guard is often recommended by physicians and dentists. It can reduce trauma to your tooth enamel caused by grinding. But many patients find it difficult to wear night guards consistently, and even when night guards are consistently worn, the guards do not stop the chewing muscles (masseters) from contracting, which means many of the problems caused by nocturnal biting and chewing persist.

Botox might help save your teeth

Botulinum toxin A (Botox®) can help to reduce problems associated with bruxism. Historically, surgical treatment was used for severe teeth grinding. More recently, many patients are finding relief for their teeth with Botox injections[5, 6]. Botox has long been injected to sculpt the jawline. And, injections in this same region of the face are providing much-needed teeth grinding relief for thousands of patients. Using Botox to treat tooth grinding is currently an off-label use—the FDA has not yet approved this drug for this use. However, like many other drugs, like the use of Botox for depression or fluoxetine for anxiety, millions are benefiting from the therapeutic effects.

Treatment details

The amount of Botox needed to achieve therapeutic results varies from person to person. Typically it is 10 to 60 units on each side. The injections take effect in about two weeks, and the effects can last from three to six months. There are some possible adverse effects: the treatment might temporarily reduce bite strength, create minor muscle pain, or in some cases create facial asymmetry or prominent cheek bones. Your doctor can help you decide if Botox is right for you.*

Ask your doctor

For this type of Botox treatment, see a physician, surgeon, or dentist that is skilled and experienced in this type of Botox injection. Not all Botox providers will have the skills, knowledge, or experience to provide this treatment successfully.
