What to Expect During a TMJ Evaluation

Wondering what happens during a TMJ evaluation? Read on to learn more. Temporomandibular joint disorder, or TMJ, can arise when the facial muscles or joints are no longer functioning smoothly. This disorder can be a complex issue caused by multiple dysfunctions at the same time, so it is common for patients to have questions about what treatment might entail. If you are considering being evaluated for TMJ disorder, it is useful to know what to expect during your appointment so you can prepare accordingly. Don’t forget to write down any questions so you remember anything you want to ask.

What happens during a TMJ evaluation

A TMJ evaluation helps the dental professional determine a customized plan of treatment. The strategy requires a multifaceted approach, so the appointment seeks to identify what is causing the dysfunction, how it has affected the patient, and what to do next.

Analysis of bite alignment

Often, the first step in a TMJ evaluation is to check how the bite is aligned. This can be done in numerous ways, from visually assessing the wear on the teeth to taking more precise measurements. The degree and direction of the misalignment can shed light on how the temporomandibular joint may be functioning incorrectly.

Facial measurements

An evaluation also often includes measurements of the face, such as the jawline and the masseter (the large muscle controlling the lower jaw). This may reveal imbalances that are placing undue strain on the TMJ and causing pain, clicking, or other symptoms.

Imaging

Imaging is an essential part of a TMJ appointment. It can show the temporomandibular joint directly, revealing the condition of the bone. Depending on the type of imaging, it may also show nerves, blood vessels, or muscle tone, which informs the treatment based on both the symptoms and the potential source of the problem.

An oral history

During the evaluation, the patient will typically be asked to describe their experiences with TMJ disorder so far. Symptoms, ways that pain or a loss of function has impacted their life, and more can all be discussed at this point so that the dentist understands the goals of treatment in the short and long term.

A customized plan

Once the dental professional has gathered enough information about the patient’s current state, they can develop a personalized plan of treatment to relieve TMJ disorder symptoms and improve the condition of the joint over time. This may include interventions such as bite guards or orthodontic care to address alignment issues. Resolving TMJ disorder often also requires patients to learn new habits, such as how to avoid stress that can cause subconscious clenching of the jaw muscles.
