If you’ve been living with jaw pain, clicking, or headaches, you may have heard the term TMJ tossed around. But understanding what your TMJ evaluation actually involves — and what to expect step by step in Airdrie — can make the whole process feel far less intimidating. At Airdrie Springs Dental, Dr. Hubert Ng takes a thorough, structured approach to diagnosing TMJ disorders. This article walks you through every stage of that process so you arrive prepared and confident.
What Is the TMJ and Why Does It Need Evaluation?
The temporomandibular joint (TMJ) connects your jawbone to your skull. It controls every movement your jaw makes — chewing, speaking, yawning. When this joint becomes inflamed, misaligned, or damaged, the results can range from mild discomfort to debilitating pain.
TMJ disorders are notoriously hard to self-diagnose. Symptoms often overlap with other conditions like tension headaches, ear infections, or sinus problems. That’s exactly why a proper clinical evaluation is so important.
A thorough TMJ evaluation does more than confirm a diagnosis. It rules out other causes, identifies contributing factors, and helps your dentist build an accurate treatment plan tailored to your needs. Without this structured process, treatment is essentially guesswork.
Step One: Your Medical and Dental History Review
Every TMJ evaluation at Airdrie Springs Dental begins with a detailed review of your health history. Dr. Ng will ask about your symptoms — when they started, how often they occur, and what makes them better or worse.
This conversation also covers your dental and medical background. Past jaw injuries, grinding habits, stress levels, and previous dental work all play a role. Even your sleep quality and posture can be relevant contributing factors.
Don’t downplay any symptom during this stage. Small details — like waking up with a sore jaw or noticing that your bite feels uneven — can be clinically significant. This history forms the foundation for everything that follows in the evaluation.
- Duration and frequency of jaw pain or clicking
- History of teeth grinding or clenching (bruxism)
- Previous jaw injuries or trauma
- Stress levels and sleep patterns
- Any prior dental treatments or orthodontic work
Step Two: The Clinical Physical Examination
After reviewing your history, Dr. Ng moves into a hands-on physical exam. This is one of the most revealing parts of a TMJ evaluation. It gives your dentist direct, real-time feedback about how your jaw is functioning.
During this exam, Dr. Ng will gently palpate the muscles around your jaw, temples, and neck. He checks for tenderness, swelling, or muscle tightness in those areas. These findings help identify whether the issue is muscular, structural, or both.
He will also observe your jaw’s range of motion. You’ll be asked to open, close, and move your jaw side to side. Deviations, limited movement, or pain during specific motions all provide valuable diagnostic information.
Listening and feeling for sounds is another key part of this step. Clicking, popping, or grinding sensations during jaw movement — called crepitus — can indicate disc displacement or joint surface irregularities.
- Palpation of jaw, temple, and neck muscles
- Assessment of jaw opening range and symmetry
- Detection of clicking, popping, or locking
- Evaluation of facial and neck muscle tension
- Checking for tenderness along the joint line
Step Three: Bite Analysis and Occlusal Assessment
How your teeth come together — your bite, or occlusion — has a direct impact on your TMJ. An uneven bite places unequal stress on the joint and surrounding muscles. Over time, this imbalance contributes to TMJ dysfunction.
During your bite analysis, Dr. Ng will use thin paper or film to map exactly where your teeth make contact. This reveals which teeth carry more pressure and whether your jaw shifts when you close. Even slight imbalances can cause significant joint strain.
If you wear a night guard or have had dental restorations, those are factored in as well. Changes to bite height from crowns, fillings, or missing teeth can all influence how your jaw aligns. The occlusal assessment helps Dr. Ng understand the mechanical root of your symptoms.
Step Four: Imaging and Advanced Diagnostic Tools
In many cases, a visual and physical exam isn’t enough on its own. Imaging gives Dr. Ng a clearer picture of the actual joint structures — including bone, disc position, and surrounding tissue.
X-rays are often the first imaging tool used. Panoramic X-rays provide a wide view of both jaw joints simultaneously. They help identify bone changes, joint spacing abnormalities, or signs of arthritis within the TMJ.
For more complex cases, a referral for a cone beam CT (CBCT) scan or MRI may be recommended. CBCT scans offer detailed 3D bone imaging. MRIs are particularly useful for assessing soft tissue, including the position and condition of the articular disc inside the joint.
These tools allow for precise diagnosis rather than assumptions. The right imaging ensures that your treatment plan addresses the actual cause of your symptoms — not just the surface-level effects.
What Happens After Your TMJ Evaluation?
Once all evaluation findings are compiled, Dr. Ng will walk you through what was discovered. He’ll explain your diagnosis in plain language — no confusing jargon. You’ll understand exactly what’s happening with your joint and why you’re experiencing your symptoms.
From there, a personalized treatment plan is developed. Depending on your diagnosis, options may include oral appliances, bite adjustments, physiotherapy referrals, or lifestyle modifications. General Dentistry services at Airdrie Springs Dental often complement TMJ treatment when bite-related dental issues are involved.
Dr. Ng may also recommend follow-up appointments to monitor your progress. TMJ treatment is rarely a one-time fix — it’s an ongoing process. Having a clear baseline from your initial evaluation makes tracking improvement much more accurate.

Frequently Asked Questions
How long does a TMJ evaluation appointment take?
Most TMJ evaluations at Airdrie Springs Dental take between 45 and 75 minutes. The length depends on the complexity of your symptoms and whether imaging is needed on the same day. Dr. Ng takes the time to be thorough rather than rushing through the process.
Is a TMJ evaluation painful?
The evaluation itself is not painful for most patients. Some areas may feel tender during palpation, especially if you’re already experiencing muscle soreness or joint inflammation. Dr. Ng works gently and checks in with you throughout the exam to ensure your comfort.
Do I need a referral to see Dr. Ng for TMJ concerns in Airdrie?
No referral is needed to book a TMJ evaluation at Airdrie Springs Dental. You can contact the practice directly to schedule your appointment. If your case requires specialist imaging or additional care, Dr. Ng will coordinate those referrals on your behalf.
Can TMJ disorders be treated without surgery?
Yes — the vast majority of TMJ cases are managed without surgery. Conservative treatments like oral appliances, bite adjustments, physical therapy, and lifestyle changes are effective for most patients. Surgical options are only considered when all other approaches have been exhausted and symptoms remain severe.
What should I bring to my TMJ evaluation appointment?
Bring a list of your current medications, any previous dental X-rays if available, and notes about your symptoms — including when they started and what triggers them. If you currently wear a night guard or retainer, bring that along as well. The more information you can share, the more productive your evaluation will be.
