The jaw joints and muscle groups that allow us to chew, swallow, speak and yawn are known as the temporomandibular joints. When there's a problem with how these joints and muscles work, it is called TMD or temporomandibular disorder. A therapeutic appliance is often required to alleviate the subsequent pain.
Some symptoms of TMD are as follows:
- Facial pain.
- Tender or sore jaw muscles due to or when clenching, grinding, chewing, and/or yawning.
- Limited opening (i.e jaw joints locking open or closed).
- Headaches and/or neck pain.
- Clicking or grinding noises when chewing or yawning.
- Chipped &/or broken teeth.
