Can botox be used to relax the muscles that make you clench your teeth?

Yes, botulinum toxin (Botox) can be used to relax the muscles that cause bruxism, or teeth clenching. Botox is a neurotoxin that blocks the signals from the nerves to the muscles, causing them to relax. Botox is one of the most common and well-studied treatments for bruxism. Botox is injected directly into the masseter and temporalis muscles, the two muscles responsible for clenching the teeth. The effects of Botox typically last for 3-4 months.
