Hello~You may have a TMJ issue. Grinding your teeth will certainly cause it. The temporomandibular (tem-puh-roe-mun-DIB-u-lur) joint (TMJ) acts like a sliding hinge, connecting your jawbone to your skull. You have one joint on each side of your jaw. TMJ disorders — a type of temporomandibular disorder or TMD — can cause pain in your jaw joint and in the muscles that control jaw movement.
The exact cause of a person's TMJ disorder is often difficult to determine. Your pain may be due to a combination of factors, such as genetics, arthritis or jaw injury. Some people who have jaw pain also tend to clench or grind their teeth, although many people habitually clench or grind their teeth and never develop TMJ disorders.
In most cases, the pain and discomfort associated with TMJ disorders is temporary and can be relieved with self-managed care or nonsurgical treatments. Surgery is typically a last resort after conservative measures have failed, but some people with TMJ disorders may benefit from surgical treatments.
Here are some of the symptoms:
•Pain or tenderness of your jaw.
•Pain in one or both of the temporomandibular joints.
•Aching pain in and around your ear.
•Difficulty chewing or pain while chewing.
•Aching facial pain.
•Locking of the joint, making it difficult to open or close your mouth
I would see an orthodontist and ask about wearing a mouth brace during the night and possibly the day. I wore one for a while, it was clear, no one can tell you have it, and it really helped.
