TMJ Dysfunction
For Patients
Understanding TMJ (Temporomandibular Joint) Disorders
The term TMJ stands for temporomandibular joint, which connects your jawbone (mandible) to the temporal bones of your skull. You have two TMJs—one on each side of your face, just in front of your ears. These joints are used every time you chew, talk, yawn, or swallow. The TMJ is a sliding joint, meaning it can both hinge and glide, allowing for smooth and powerful jaw movement. A small disc made mostly of cartilage acts like a cushion between the bones, helping to absorb pressure and stabilize movement.
TMJ dysfunction (TMD) refers to a group of complex and often painful disorders that affect the jaw joint and surrounding muscles. Symptoms may include jaw pain, clicking or popping sounds, limited range of motion, headaches, neck pain, and discomfort while chewing. Because the TMJ interacts with muscles, bones, discs, and nerves, it can be the cause of—or the victim of—other related issues. These problems may affect not just the joint, but the overall alignment and function of the jaw. If you’re searching for help to fix TMJ or are looking for a TMJ cure, understanding the anatomy is the first step toward relief.

TMJ Anatomy and Sources of Dysfunction
The jaw functions through a delicate balance of joints, bones, muscles, and ligaments. When one part of the system isn’t working properly, it can result in TMJ disorders. For example, the trigeminal nerve, which branches near the TMJ, may cause facial pain that mimics other conditions. If a ligament in the joint is damaged, it can cause the disc to dislocate, creating pain, popping, or locking of the jaw. Likewise, injuries to the surrounding muscles can also alter jaw movement or trigger chronic discomfort.
What Causes TMJ Disorders?
A variety of factors may contribute to TMJ problems, including
- Poor dental alignment or a misaligned bite
- Teeth grinding (bruxism)
- Poor posture
- Skeletal malformations
- Injury or trauma, such as whiplash or jaw impact
It’s estimated that as many as 25% of people may experience one or more symptoms of TMJ dysfunction. If you’re experiencing any of these issues and looking for TMJ near me, it’s important to find a provider who offers comprehensive TMJ treatment tailored to your needs.
Is There a Way to Fix or Cure TMJ?
The good news is that TMJ disorders can be treated—often without surgery. Because the bones and soft tissues involved are living, adaptable structures, they respond well to targeted, non-invasive therapies. Whether you’re dealing with chronic jaw tension, popping joints, or headaches related to jaw dysfunction, there are modern options available to fix TMJ and reduce jaw pain. At specialized centers offering treatment for jaw pain, therapies may include bite adjustments, muscle relaxation techniques, oral appliances, and posture correction. So if you’re searching for a TMJ cure, rest assured—there is hope for healing and long-term relief.

Jill Krstajic2024-10-31Trustindex verifies that the original source of the review is Google. It is not an understatement to say that Dr Goodfellow and his staff have greatly improved the quality of my life! My TMJ pain was unbearable and as a Dental Hygienist I was actually skeptical that the treatment would work, it did and I am grateful! I would gladly recommend Dr Goodfellow for anyone suffering TMJ and Sleep Issues. Lanndis De Lallo2024-09-30Trustindex verifies that the original source of the review is Google. This device changed my life. I have had TMJ for as long as I can remember with a long history of orthodontic work from childhood. For the first time as an adult, I can control my jaw pain, clicking, locking and tension headaches with the night time appliance, which I wear every night - I can feel the difference even going one night without it. The daytime appliance also makes a big difference and now I can wear it periodically. Dr. Goodfellow, Cathie, Tina and the entire team are delightful, helpful and I can't thank them enough for helping me implement this life changing, non-surgical solution to my TMJ!

Dr. Goodfellow and his staff provided me with a non-invasive appliance one for the day and one for night and within 6 months I was pain and click free.
