Botulinum toxin injections

Botulinum toxin (commonly known as Botox®) is an effective treatment for jaw and head pain.  Botox® can help severe teeth grinding by reducing the frequency or intensity (or both) of jaw muscle contractions. It can also reduce pain in the region and studies have shown that it can reduce muscular as well as nerve pain.
