It could be TMD: Temporomandibular Joint Dysfunction
Common Signs and Symptoms:
Pain can occur in the jaw and related muscles, producing headaches and even migraines. It can be present at anytime, even when the jaw is not active. The intensity of the pain can manifest as headaches, locked jaw or toothaches from clenching.
You may have clicking and/or popping when moving your jaw. For some, the sound is subtle, for others it can be loud and cause embarrassment in group settings.
The inability to open wide without pain is a common complaint. You may experience a limited range of motion or find your jaw “locking.” These episodes may be brief, but can become more frequent if they are not addressed.
