TMD & TMJ Pain
Causes, Symptoms & Treatment
Temporomandibular disorder (TMD) refers to problems affecting the jaw joint and surrounding muscles. The temporomandibular joint (TMJ) connects the jaw to the skull, and dysfunction may cause discomfort, restricted movement or clicking sounds. Symptoms can develop gradually or suddenly — a professional dental assessment helps identify contributing factors and guide appropriate management.

The Jaw Joint
What Is the Temporomandibular Joint (TMJ)?
The temporomandibular joint (TMJ) is the joint that allows movement of the jaw — for speaking, chewing, yawning and other everyday functions. You have one on each side of your face, located just in front of each ear.
It connects the lower jaw (mandible) to the skull, and is one of the most frequently used joints in the body. It combines a hinge-like opening movement with a sliding action, enabling a wide range of jaw movement.
The joint functions alongside muscles, ligaments and a small cartilaginous disc that cushions movement. These structures work together to allow smooth, coordinated jaw function during normal use.
A clinical evaluation helps assess joint function — examining the range of movement, identifying any clicking or tenderness, and considering how the muscles and teeth interact with joint mechanics.
Symptoms & Warning Signs
Jaw pain or tenderness
Aching or sharp pain around the jaw joint, in front of the ear, or across the jaw muscles — often aggravated by chewing or speaking.
Clicking, popping or grinding sounds
Audible or felt sounds during jaw movement — from soft clicks to more pronounced popping or grinding.
Difficulty opening or closing the mouth
A sense of restriction, stiffness or uneven movement when opening wide, closing firmly or moving the jaw side to side.
Headaches or facial pain
Tension-type headaches, temple pain or generalised facial discomfort linked to muscle overactivity and joint dysfunction.
Ear-related symptoms
Earache, a sense of fullness in the ear, or ringing in the ears — without an underlying ear infection — can sometimes accompany TMD.
Jaw locking
In more pronounced cases, the jaw may briefly lock open or closed — requiring gentle manipulation to return to normal movement.
Symptoms vary depending on cause and severity. Persistent or worsening TMJ symptoms warrant professional dental assessment.
Understanding the Condition
What Is Temporomandibular Disorder (TMD)?
Temporomandibular disorder (TMD) refers to dysfunction or pain affecting the TMJ and its surrounding muscles. It is an umbrella term covering a range of conditions, from short-lived muscle tension to more established joint problems.
TMD may involve joint structures — such as the disc or surrounding ligaments — or muscular components, where tightness and overactivity of the chewing muscles contribute to symptoms. In many cases, both are involved simultaneously.
Symptoms can vary in severity and duration, from mild, intermittent discomfort to more persistent pain and restricted movement. TMD may affect one or both sides of the jaw, and the pattern of symptoms provides valuable diagnostic information.
A clinical evaluation helps determine the underlying cause — distinguishing between muscular, joint-related and other contributing factors, and guiding a tailored management plan.
Contributing Factors
Common Causes and Contributing Factors
TMD is often multifactorial, with several contributing factors interacting. Identifying these is an important part of a comprehensive management plan.
Teeth grinding or clenching (bruxism)
Repeated grinding or clenching places sustained load on the jaw joint and its surrounding muscles — one of the most commonly identified contributing factors in TMD.
Jaw injury or trauma
A previous blow to the face, whiplash-type injuries or impact from contact sport can affect the joint, disc or surrounding tissues and contribute to longer-term dysfunction.
Bite alignment issues
Irregularities in how the upper and lower teeth meet together can alter jaw mechanics and contribute to muscle strain or joint discomfort in some cases.
Stress-related muscle tension
Emotional stress often manifests as sustained clenching of the jaw or tightening of the facial muscles — contributing to muscular forms of TMD.
Arthritis affecting the joint
Degenerative or inflammatory joint conditions, including osteoarthritis and rheumatoid arthritis, can involve the TMJ and contribute to pain or restricted movement.
Habitual jaw movements
Habits such as chewing gum, nail biting, chewing on pen lids, or resting the chin on the hand may contribute to repetitive strain of the jaw joint and muscles.
Why It Matters
Potential Risks if Not Addressed
Left unmanaged, TMD can result in persistent pain or discomfort — affecting day-to-day comfort, concentration and quality of life. Chronic discomfort can also contribute to wider tension-type headaches and facial pain.
Ongoing dysfunction may lead to reduced jaw mobility and worsening joint sounds or dysfunction. In some cases, this can include episodes of jaw locking or progressive changes in how the joint moves.
Severe or persistent TMD can impact eating and speaking — making it uncomfortable to chew certain foods or open the mouth fully. In complex cases, more involved management may be required, and early assessment often supports more conservative approaches.
Your Options
Treatment and Management Options
Treatment depends on clinical assessment. Management varies based on cause, and a personalised approach is recommended following professional examination.
Dental Appliances (Splints & Guards)
Custom-made occlusal splints or night guards designed to reduce load on the joint and muscles — tailored to each patient and adjusted as needed.
Learn MoreManagement of Teeth Grinding
Addressing bruxism is often central to TMD care — combining custom appliances with lifestyle and behavioural strategies where appropriate.
Learn MoreAdvice on Jaw Habits & Movement
Guidance on gentle jaw use, avoiding habits such as chewing gum or nail biting, posture considerations and soft-food recommendations during flare-ups.
Sports Guards
Custom sports guards offering tailored protection for patients involved in contact sport, helping reduce risk of jaw trauma contributing to TMD.
Learn MoreMonitoring of Symptoms
Ongoing review of jaw function, symptom pattern and any changes over time — allowing the management plan to be adjusted as required.
Learn MoreReferral Where Appropriate
Where indicated, onward referral to a specialist in orofacial pain, physiotherapy or related disciplines may be discussed as part of a wider management approach.
Your First Step
Importance of Professional Dental Assessment
TMD symptoms may have multiple causes — muscular, joint-related, or linked to habits, bite or other factors. Professional examination allows these contributing factors to be identified and weighted, forming the basis of an effective management plan.
Examination allows bite and jaw function to be assessed, tooth wear patterns to be reviewed, and any associated conditions — such as bruxism — to be considered. This comprehensive approach supports more accurate diagnosis and treatment planning.
Treatment planning is tailored to individual needs. Early assessment may help manage symptoms more effectively, reduce the risk of progression and support more conservative long-term management.
What to Expect
- 1Discussion of your symptoms — including pain, clicking, restricted movement, locking episodes, headaches or ear-related symptoms
- 2Review of your medical, dental and lifestyle history — including any previous jaw injuries, stress levels, sleep habits and relevant medications
- 3Examination of jaw movement — assessing the range of opening, symmetry, deviation and any clicking or crepitus during movement
- 4Palpation of the jaw muscles and joint for tenderness, tightness or signs of overactivity, along with evaluation of related head and neck musculature
- 5Assessment of tooth wear patterns, bite relationships and any signs of bruxism contributing to joint or muscle strain
- 6Personalised management plan — which may include a custom splint, advice on jaw habits, referral where appropriate and ongoing monitoring
