Teeth griding/clenching (Bruxism)

Bruxism is a condition characterized by involuntary teeth grinding or clenching, often during sleep, but for many also while awake. It can lead to various issues, including tooth and gum deterioration, jaw pain, headaches, and disrupted sleep. Finding effective treatments for bruxism is crucial for improving patients’ quality of life.

How Does Botulinum Toxin A Help?

Botulinum toxin A (commonly known as "Botox") has gained attention as a  treatment for bruxism. Here’s how it works:

1. Muscle Relaxation: Botulinum toxin A injections into the masseter muscles (the jaw muscles responsible for clenching) cause temporary muscle paralysis. This relaxation reduces the force exerted during grinding, protecting teeth and minimizing jaw pain.

2. Pain Reduction: Botulinum toxin A not only decreases biting strength but also alleviates pain associated with bruxism. Studies show that these injections can reduce pain levels significantly.

3. Long-Lasting Effects: the medication's effects are evident within weeks, sometimes as soon as a few days and, peak between 5 and 8 weeks, and last up to 24 weeks. This makes it an attractive option for those seeking symptom relief.

4. Night guards do not prevent the muscles from becoming ever stronger over time, as they are exercised when performing the clenching and/or grinding. Treatment with Botulinum toxin A allows this muscle to atrophy and become weaker with repeated treatments.

5. This treatment is also used to slim the jaw of very square-jawed people, creating a more feminine and slimmer face. 

Q&A: 

• Will I still be able to chew and eat normally?  Yes - the jaw may tire if you have to eat a lot of crunchy food such as granola or carrots, but does not prevent regular eating.

Evidence-Based Findings

Several studies have investigated Botulinum toxin A’s efficacy in treating bruxism. A systematic review1 found that BTX-A injections can:

• • Reduce the frequency of bruxism episodes.

  • Decrease pain levels.

  • Lower the maximum occlusal force generated by bruxism.

  • Offer superior efficacy compared to control groups treated with placebos or traditional methods.
