If you ever wake up with a sore jaw in the morning, it could be due to clenching your teeth at night. Your muscles of mastication allow you to chew your food, but when they contract for long periods of time they can become sore. If your muscles of mastication are contracting for long periods during the night, you can wake up with a sore jaw. Other signs are wear patterns in your teeth, chipping and cracking porcelain crowns, and pain to palpation of your massetter muscles. Botox injections help reduce the force of contraction of your massetters and temporalis muscles. These injections can relax the muscles for 3-4 months at a time. Ask Sedation Dental Center about botox injections as a way to manager jaw pain and head aches.
