A surprising, newer treatment for bruxism is Botox, where the neurotoxic protein is injected into the temporal and masseter muscles in the jaw.

A report based off a small sample in the journal Neurology found that subjects given Botox versus a placebo for bruxism found their symptoms “very much improved” or “much improved.”

Botox blocks nerve signals to the muscle where it’s injected, so the muscle relaxes or, depending on how much botox is used, stops contracting.
