Can Orthodontic Treatment Stop My Jaw from Popping and Clicking?

Joint noises, or noises that arise in the temporomandibular joints, can take several different forms. Some patients describe popping or clicking. Other describe hearing grinding as they open and close their mouths. No matter how they are described, joint sounds are common and can occur before, during, orthodontic treatment. Do braces or aligners cause joint sounds and can they cure them? Do joint disorders begin as noises and eventually progress to pain?

Joint noises may just be due to your anatomy
Jaw joint issues can involve muscles, ligaments, tendons, and/or the cartilages associated with the joints. Many times these problems are due to the anatomy of the patient's joints. Some folks' joints just make noises or move roughly because of their shape and size. It is not uncommon for patients' ankles to pop when they stand up, but rarely do they seek treatment for that noise. A pop in the jaw joint however is much more noticeable because it occurs close to the ear where the patient can hear it.

What causes the the TMJ to pop?
So what do we know about TMJ noises and what causes them? First of all, the jaw joints are like many other joints in the body. There are two bones that come together with a piece of padding (a disc made of cartilage) between them. The disc is held between the bones by a ligament from behind and a muscle from the front. As the joint functions, the muscle pulls on the disc to keep it centered between the two bones. When it works perfectly, it functions almost silently.

If the ligament is loose so that it doesn't hold the disc in the right place however, the disc travels a little too far upon opening and then suddenly pop back into place when the ligament finally becomes taught. If the muscle pulls too hard on the front of the disc, it can also hold it too far forward until the ligament ultimately pulls it back into place. Ligaments can be naturally loose, get loose during childbirth (when all the ligaments in the body relax), or become damaged by trauma. The muscles can contract too much if they have been busy chewing (gum, bagels, etc.), clenching, or grinding. Clenching or grinding can actually cause spasms in the chewing muscles which can be painful as well as pull the disc forward.

TMJ pops and clicks are very common
Nearly half of American women report they have had a pop or a click in their jaws while about one-fourth of the men report the same. While some popping may not be related to an identifiable event, many patients know exactly what sets it off. Studies have indicated that more than 50% of TMJ symptoms are attributable to stress alone. That helps explain the rise in calls we get during the last two weeks of the school year. Almost without fail our patients identify that their symptoms arrived about the same time as their finals and associated end-of-year projects. While there definitely are TMJ conditions that warrant treatment, most popping and clicking is not serious. Sometimes just recognizing the relationship between these noises and their stress level is all that is needed to get a patient on the road to recovery.

TMJ noises don't usually progress to TMJ pain
Finally, the scientific literature has determined that joints that start making popping or clicking sounds do not progress into more serious, painful temporomandibular disorders. While some patients may have both issues, doctors have found that those who have joint noises do not predictably develop TMD and neither do those with joint pain always have a history of pops and clicks.
