Orthodontics and TMJ: What’s the Real Connection? At Joe Orthodontics, we’re here to help.
Every May, our office sees an uptick in calls from parents of high-school-aged teens concerned about jaw pain or “TMJ” symptoms. Many assume these issues are caused by their child’s bite and schedule an appointment with an orthodontist. But what is the real relationship between temporomandibular disorders (TMD) and orthodontic treatment?
Orthodontics And TMJ: Extensive Research Has Studied the Bite-TMJ Link
Since a landmark 1987 lawsuit in Michigan, thousands of scientific studies have examined whether orthodontic treatment affects the temporomandibular joint (TMJ). Researchers studied different types of malocclusion (bad bites) and various orthodontic treatments to determine if there is any cause-and-effect relationship between braces and TMJ health.
Orthodontics Neither Causes Nor Cures TMJ Disorders
The consensus from decades of research is clear: orthodontics does not cause TMJ problems, nor does it cure them. In general, malocclusion is not linked to a higher risk of TMJ pain. There are only two exceptions:
- Posterior crossbite – where the jaw shifts to one side when biting.
- Anterior open bite – where the front teeth don’t touch, and all biting force is on the back teeth.
Other common bite issues, including overbites, underbites, crowding, or spacing, have not been shown to cause TMJ disorders. Similarly, treatments such as headgear, extractions, rubber bands, or even jaw surgery are not linked to TMJ problems.
Other Factors Can Contribute to TMJ Pain
Jaw pain can have many causes unrelated to your bite, including: When it comes to orthodontics and TMJ, having the right information makes all the difference.
- Functional habits like teeth clenching or grinding (bruxism)
- Degenerative conditions such as arthritis
- Medical conditions like tumors or infections
Interestingly, many patients with severe TMJ pain have ideal bites, while many with “bad bites” have no symptoms at all. This observation supports the research showing that TMJ issues and orthodontic treatment are largely independent.
Reliable Expert Guidance
For the most up-to-date information, Dr. Jeffrey Okeson—a leading authority on occlusion and TMJ disorders—offers lectures and resources that objectively separate orthodontics from TMJ treatment.
If you or your child are experiencing jaw pain, an orthodontic evaluation may not be necessary unless other bite-related issues are present. It’s always important to consult with a TMJ or dental specialist to identify the true cause of discomfort.
