What Is Botox for TMJ?
Botox for TMJ is an injection of Botox placed into the masseter. The masseter is the thick muscle at the angle of the jaw, and it is the muscle that closes the teeth together when you bite down or clench. The injection interrupts the nerve signal reaching it, so the muscle contracts with less force and the joint, the tissue around it and the teeth carry less load through the day and overnight. Clenching eases across the first weeks, and the effect is at its fullest between weeks four and eight. Treating the masseter with Botox is an off-label use, outside the indications the FDA has approved.
