Does Your Jaw Click? Understanding TMJ Disorders
A clicking jaw can be a sign of a temporomandibular disorder (TMD) — a group of conditions affecting the jaw joint, the small cartilage disc that cushions it, and the muscles and tissues around it. Alongside clicking or popping, TMD can bring jaw pain, restricted opening, headaches, earaches and neck tension, which are often attributed to other causes. Most cases respond to conservative, non-surgical care such as self-care changes and a custom night guard; surgery is considered only when those do not bring relief.

The temporomandibular joint (TMJ) is the hinge-like joint that connects your jawbone to your skull, located just in front of each ear. You use this joint every time you talk, chew, yawn, or swallow — making it one of the most frequently used joints in your body. When something goes wrong with this joint or the muscles that control it, the result is a temporomandibular disorder (TMD).
At Orion Dental in Scarborough and Milton, we evaluate TMD symptoms as part of our comprehensive dental examinations. This guide covers what TMD is, how to recognise the symptoms, what causes it, and how it can be managed.

What Is a TMJ Disorder?
A TMJ disorder (TMD) encompasses a group of conditions that affect the temporomandibular joint, the jaw muscles, and the surrounding tissues. The joint works like a sliding hinge, with a small cartilage disc that cushions the movement between the jawbone and the skull. When this disc shifts, the joint becomes inflamed, or the surrounding muscles are strained, you may experience pain, clicking, or restricted movement.
TMD can be broadly categorised into three types: muscle disorders (pain in the muscles that control jaw movement), joint disorders (problems with the disc or joint surfaces), and degenerative conditions (arthritis affecting the TMJ). Some patients experience a combination of these.
Symptoms of TMJ Disorders
TMD symptoms vary widely from person to person. They may come and go, or they may be persistent. Common signs include:
TMD Symptoms to Watch For
- Clicking, popping, or grating sounds when opening or closing the jaw
- Pain or tenderness in the jaw, especially when chewing
- Aching pain around or in front of the ear
- Headaches, particularly in the temples or forehead
- Stiff or sore jaw muscles, especially in the morning
- Difficulty opening the mouth wide or jaw "locking" in an open or closed position
- A sudden change in how the upper and lower teeth fit together
- Neck or shoulder pain associated with jaw tension
Not Just Jaw Pain
Many patients don't initially connect their symptoms to the jaw. Headaches, earaches, and neck tensionare frequently associated with TMD but often attributed to other causes. If these symptoms are recurring and you notice jaw involvement, it's worth mentioning to your dentist.
What Causes TMJ Disorders?
TMD often results from a combination of factors rather than a single cause. Understanding these contributors can help guide treatment:
| Contributing Factor | How It Affects the TMJ |
|---|---|
| Teeth Grinding / Clenching (Bruxism) | Places excessive, repetitive force on the TMJ and fatigues the jaw muscles |
| Stress & Anxiety | Causes unconscious jaw clenching and increases muscle tension throughout the head and neck |
| Facial Trauma | A blow to the jaw or head can displace the disc, damage cartilage, or inflame the joint |
| Arthritis | Osteoarthritis or rheumatoid arthritis can degrade the cartilage and bone surfaces of the TMJ |
| Misaligned Bite | When teeth don't fit together properly, uneven forces are distributed to the joint |
| Excessive Chewing | Habitual gum chewing, nail biting, or chewing on hard objects strains the joint over time |
| Missing Teeth | Gaps can cause the remaining teeth and jaw to shift, altering the bite and TMJ mechanics |
In some cases, no clear cause is identified. Hormonal factors may also play a role, as TMD is more prevalent in women, particularly during reproductive years.
Jaw Pain Affecting Your Daily Life?
A comprehensive TMJ evaluation can identify the source and help you find relief.
How TMJ Disorders Are Diagnosed
Diagnosing TMD involves a thorough clinical examination. At Orion Dental, the evaluation typically includes:
The TMD Evaluation Process
Symptom History
Your dentist will ask about your symptoms, their duration, triggers, and any related health conditions or habits.
Physical Examination
Palpation of the jaw muscles and joint, assessment of jaw range of motion, and listening for clicking or grinding sounds.
Bite Analysis
Evaluating how your upper and lower teeth come together to identify any bite irregularities contributing to the problem.
Imaging
Digital X-rays or panoramic images to assess the bone structure, joint space, and rule out other conditions.
Treatment Options for TMJ Disorders
The good news is that the vast majority of TMD cases respond well to conservative, non-surgical treatment. Your dentist will recommend a plan based on the type and severity of your condition.
Self-Care and Lifestyle Changes
At-Home TMD Management
- Eat soft foods and cut food into smaller pieces to reduce chewing strain
- Avoid extreme jaw movements — wide yawning, loud singing, or excessive gum chewing
- Apply warm compresses to the jaw area for 15–20 minutes to relax muscles
- Use cold packs for acute inflammation (10 minutes on, 10 minutes off)
- Practise jaw relaxation: lips together, teeth apart, tongue resting on the roof of the mouth
- Manage stress through exercise, mindfulness, or other relaxation techniques
- Avoid resting your chin on your hand or cradling the phone between shoulder and ear
Professional Treatments
Custom Night Guard
An occlusal splint worn during sleep prevents grinding and clenching, reducing strain on the TMJ and jaw muscles.
Bite Adjustment
Minor reshaping of tooth surfaces to improve how your teeth fit together, distributing forces more evenly.
Physical Therapy
Targeted jaw exercises, stretches, and manual therapy techniques to improve range of motion and reduce muscle tension.
Medication
Over-the-counter pain relief, muscle relaxants, or anti-inflammatory medications may be recommended for symptom management.
Orthodontic Correction
When bite misalignment is a contributing factor, Invisalign or other orthodontic options may help long-term.
Restorative Dentistry
Replacing missing teeth with implants, bridges, or dentures can restore proper bite mechanics and relieve TMJ stress.
A custom night guard is one of the most commonly recommended treatments for TMD associated with bruxism. Unlike over-the-counter options, a custom-fitted guard ensures proper alignment and comfort. For cases involving bite issues, Invisalign or orthodontic treatment may be part of the long-term plan. When missing teeth are contributing to the problem, dental implants or bridges can restore function and reduce TMJ strain.
Conservative Care Comes First
Conservative treatment is usually tried first and helps many people with TMD. Surgery is only considered when other approaches have not provided adequate relief and imaging confirms a structural issue that may benefit from surgical intervention.

Frequently Asked Questions
Common questions about TMJ disorders
What is the difference between TMJ and TMD?
TMJ stands for temporomandibular joint — the joint itself. TMD stands for temporomandibular disorder — the condition that affects the joint. In everyday conversation, many people use "TMJ" to refer to the disorder, but the correct clinical term is TMD.
Is jaw clicking always a sign of a TMJ disorder?
Not necessarily. Occasional jaw clicking without any discomfort is quite common and may not require treatment. However, if the clicking is accompanied by pain, locking, difficulty opening your mouth, or changes in your bite, it is worth having it evaluated by a dentist.
Can stress cause TMJ problems?
Yes. Stress is a significant contributing factor. Many people unconsciously clench their jaw or grind their teeth when stressed, which places excessive force on the TMJ and surrounding muscles.
What kind of dentist treats TMJ disorders?
General dentists are trained to evaluate and manage TMD. For complex cases, they may refer you to a specialist in orofacial pain or an oral surgeon. At Orion Dental, we assess TMD symptoms as part of our comprehensive examinations.
Will a night guard help with TMJ pain?
A custom night guard (occlusal splint) can help many patients by preventing teeth grinding and clenching during sleep, reducing the strain on the TMJ. However, the right treatment depends on the specific cause of your TMD.
Can TMJ disorders go away on their own?
Mild TMD symptoms sometimes resolve with self-care measures such as soft diet, jaw rest, and stress management. However, persistent or worsening symptoms should be professionally evaluated to prevent further joint damage.
