TMJ Diagnosis
How Temporomandibular Joint Dysfunction Is Diagnosed
In order to diagnose Temporomandibular Joint Dysfunction (TMD) a detailed structured assessment must be carried out.
TMJ related symptoms can affect the patient's jaw, ears, head and neck and, for this reason, we have to evaluate not just the joint itself, but how it functions in terms of the entire system as a whole. Our TMJ Clinic specialist focuses on the patient's symptoms and hones in on pinpointing the actual causes of the dysfunction.
TMJ Diagnosis Complexities
The temporomandibular joint is closely connected to facial muscles, bite alignment, nerves (in both head and face) plus muscles in the neck and shoulders. Identifying the source of the dysfunction can be quite a complex process.
People with a TMJ Dysfunction often mistake the symptoms they are experiencing for an ear condition, sinus infection, migraine or tension headache and even neck pain. Many of our patients have already sought multiple opinions from their GP or audiologist before having a full jaw joint assessment.
A structured diagnostic approach is always the best approach to identify the exact contributory factors.
What Does TMJ Assessment Entail?
A fully comprehensive TMJ assessment typically involves several key steps including;
Detailed History
Getting to understand your symptoms is the first thing that needs to be done. For this a patient needs to give important details as to when the symptoms started to present themselves and if they are happening all the time or on more of an intermittent basis. Other important information includes whether the patient has had any history of injury or trauma to the jaw or if they have any clenching or teeth grinding habits that they are aware of. If the patient is experiencing headaches, ear or neck pain is important to establish and if they have had any prior treatments. These initial processes help to get a clear picture of how the patient's condition has developed over time.
Jaw Movement Assessment
The way your jaw moves provides important information about joint function. We need to establish if you can open your mouth fully without any feelings of restriction. We also need to look at any possible movements to one side as you open and close your mouth or if there is any clicking or locking happening. Any type of irregular movement patterns may indicate joint or disc involvement.
Joint Evaluation
The temporomandibular joints themselves are assessed for sort of clicking or popping happening. We also examine for any movement pain points and any signs of inflammation. This helps us to figure out whether the issue is primarily related to the joint itself, muscle related, or a perhaps even a combination of both.
Bite Analysis (Occlusion)
How your top and bottom teeth meet plays an important role in the jaw's overall functionality. During the assessment process we examine the alignment when your mouth closes to determine if the pressure is distributed evenly. We look for signs of wear from grinding, bite imbalance or possible shifting. An uneven bite is a common contributory factor to persistent joint strain over time.
Muscle Examination
The muscles that control jaw movement are carefully looked at. This examination can involve applying gentle palpation (pressure) to jaw muscles, temple muscles and neck muscles, Areas that are tender or tight can be an indication of muscle overactivity or fatigue.
Pinpointing Contributing Factors
Instead of focusing on just a single cause, diagnosis will often entail identifying a combination of contributing factors. These can include;
- Bruxism (clenching or grinding)
- Tense muscles
- Joint instability
- Disc displacement
- Bite imbalance
Understanding these factors is key to developing an effective treatment plan to treat TMJ dysfunction.
Is Imaging Required?
In some cases, our dentist may recommend a scan for deeper analysis. The types of scan can vary and may include; an MRI (Magnetic Resonance Imaging) scan, and, in some instances,
This might include:
- X-rays
- MRI (Magnetic Resonance Imaging) scan
- CBCT (Cone Beam
- Computed Tomography) scan
These types of imaging scans are typically used in cases where there are suspected structural joint issues, where the patient's symptoms are severe or simply to get more detail to assist diagnosis. That said, TMJ cases can be diagnosed through clinical examination alone in many cases without the need for scans..
Structured Diagnosis Importance
A clear diagnosis is hugely important because, without it, treatment may only provide temporary relief. A structured approach helps the dentist identify the root cause of your TMJ dysfunction. It helps pinpoint possible muscle and joint problems and map out a targeted personalised treatment plan. This type of plan is key, especially for patients who have been having ongoing or unresolved symptoms.
When Should You Consider Getting a TMJ Assessment?
It is recommended you get a TMJ assessment if you experience:
- Consistent jaw pain
- Clicking or popping in your jaw that feels uncomfortable
- Straining to your mouth
- Episodes of jaw locking
- Frequent headaches
- Ear symptoms with no obvious
- Tension or fatigue in your face
The sooner you can get a diagnosis for your TMJ issues the better.
Early assessment can often increase the effectiveness of more straightforward treatments.
What Happens Next?
Once the underlying factors causing your TMJ issues have been identified, your dentist can devise a personalised treatment plan to reduce the strain on the joint. Following assessment, the dentist will look at ways to improve your bite balance, support muscle relaxation and to protect your joint during recovery.
