Temporomandibular Disorders (TMD)
Temporomandibular disorders (TMD) are a group of conditions that may affect the temporomandibular joint (TMJ), which connects the lower jaw to the skull, as well as the chewing muscles and surrounding tissues. Symptoms such as jaw pain, restricted movement or painful joint sounds do not have the same cause in every patient. For this reason, assessment is individualised and based on the history of symptoms, clinical examination and, when necessary, additional investigations.
What are the temporomandibular joint and TMD?
The temporomandibular joint allows the lower jaw to move during speaking, chewing, swallowing and yawning. In addition to the joint itself, the chewing muscles, ligaments and articular disc contribute to the coordination of these movements.
TMD is not a single disease. It may include conditions arising from the joint, pain related to the masticatory muscles, or situations in which both are involved.
For this reason, the phrase “jaw joint problem” does not by itself indicate a specific diagnosis. The location of pain, when it began, whether it changes with movement and how it affects jaw function should be evaluated in detail.
What symptoms may occur with temporomandibular disorders?
Symptoms that may be associated with TMD can vary from person to person. Findings that may require assessment include:
- Pain or tenderness in the jaw joint or chewing muscles
- Pain around the ear, temple, face or jaw
- Difficulty opening or closing the mouth
- Restricted jaw movement or a feeling of locking
- Pain or fatigue while chewing
- Painful clicking, grinding or catching during jaw movement
- The lower jaw deviating to one side during opening
- A sudden change in the way the teeth meet
These symptoms are not specific to TMD. Dental pain, ear conditions, certain types of headache, nerve-related pain and other health problems may cause similar symptoms.
Other possible causes may therefore need to be considered when determining the appropriate approach.
Does jaw clicking always require treatment?
Clicking or popping sounds from the temporomandibular joint can be relatively common.
Joint sounds that are not accompanied by pain, restricted movement, locking or loss of function do not always require treatment. A joint sound alone does not necessarily indicate a serious joint disorder.
Clinical assessment may be appropriate if the sound has recently developed, is becoming more frequent, is associated with pain or is accompanied by a change in mouth opening.
Treatment decisions should be based on the patient’s symptoms, examination findings and the effect on daily function rather than on the presence of sound alone.
What causes TMD?
There is no single cause of TMD that applies to every patient.
In some cases, trauma to the jaw or face, excessive loading of the joint and muscles, prolonged clenching, certain rheumatic conditions or changes within the joint structures may contribute.
In many patients, however, one specific cause cannot be identified.
Sleep, stress, pain sensitivity and daily habits may influence the severity of symptoms. However, it is not appropriate to attribute all TMD symptoms solely to stress, clenching or the way the teeth meet.
Contributing factors are considered together with the patient’s history and clinical findings.
How is TMD assessed?
During the first consultation, the onset, duration, location and severity of pain may be discussed together with its relationship to jaw movement, any history of locking, trauma, existing medical conditions and previous treatments.
The head, neck, face, temporomandibular joints and chewing muscles may be examined. Mouth opening, jaw movements, joint sounds and the way the teeth meet can also be assessed.
Imaging is not required for every patient.
Depending on the clinical findings, panoramic radiographs, magnetic resonance imaging (MRI) or computed tomography (CT) may be considered.
TMD should not be diagnosed solely on the basis of one image, a joint sound or an analysis of the bite.
When necessary, assessment may be coordinated with oral and maxillofacial surgery, physiotherapy, rheumatology, neurology or other relevant healthcare disciplines.
Should other causes of jaw pain be ruled out first?
Pain around the jaw, face or ear does not always originate from the temporomandibular joint.
Dental decay and infection, gum problems, sinus or ear conditions, certain headaches, nerve-related pain and trauma may produce symptoms in similar areas.
It is therefore important to distinguish between possible sources of pain during assessment.
If the symptoms cannot be explained by TMD or if findings suggest another condition, referral to the appropriate healthcare professional may be recommended.
Safe and appropriate treatment planning depends on establishing the correct diagnostic distinction.
What is the initial approach to TMD treatment?
Many TMD symptoms may improve over time.
For this reason, reversible, lower-risk and conservative approaches are often preferred as the first step.
The aim is to reduce pain, maintain jaw function and help the patient recognise behaviours that may aggravate symptoms.
Depending on the individual, temporary dietary modification towards softer foods, avoiding chewing gum, avoiding excessive mouth opening, keeping the teeth apart at rest, appropriate heat or cold application and controlled jaw exercises may be suggested.
If medication is considered necessary, it should be planned by a physician or dentist with the patient’s health status, other medications and potential adverse effects taken into account.
When may an occlusal splint be used?
A stabilisation splint or similar oral appliance may be considered as part of the treatment plan in selected patients.
In some patients, these appliances may help manage loads associated with clenching or grinding, protect tooth surfaces or assist with monitoring symptoms.
A splint is not a single or guaranteed solution for every type of jaw pain.
The type of appliance, wearing schedule and follow-up plan should be determined individually.
An appliance that does not fit properly or is used without appropriate supervision may produce unwanted bite changes or aggravate symptoms.
For this reason, prolonged use of an over-the-counter appliance without clinical assessment is not recommended as a substitute for individual evaluation and follow-up.
Are teeth clenching and grinding the same as TMD?
Bruxism, which includes clenching or grinding the teeth, is not the same condition as TMD.
Bruxism may increase the load on the chewing muscles and contribute to pain in some people, but not everyone who clenches develops TMD, and not every patient with TMD has bruxism.
Findings such as tooth wear, morning fatigue in the jaw muscles, tenderness or awareness of clenching may be considered during assessment.
Treatment should not be based on a promise to eliminate clenching completely.
Sleep, stress, medications, lifestyle habits and the condition of the teeth may all be considered as possible contributing factors.
When may exercises and physiotherapy be considered?
Individual exercises may be recommended to improve controlled jaw movement, relax the muscles and support everyday function.
For some patients, physiotherapy may contribute to treatment through manual techniques, posture assessment and jaw movement training.
Exercises should not be performed randomly or in a way that forces the jaw through pain.
Not every exercise is appropriate for every type of TMD.
If pain increases, the jaw locks or movement becomes noticeably restricted, the exercise should be stopped and the clinic should be contacted.
Does orthodontic treatment correct TMD?
Braces or clear aligner treatment should not be regarded as an automatic or primary treatment for TMD.
Current evidence does not support routinely changing tooth position or the bite permanently solely for the purpose of treating TMD.
A patient may have a separate orthodontic problem that requires treatment independently of TMD.
In such cases, joint and muscle symptoms are assessed separately, and the aims, limitations and follow-up plan of orthodontic treatment are clearly defined.
Irreversible changes to the bite should not be carried out solely because of a joint sound or unexplained facial pain.
When may surgery or irreversible procedures be considered?
Surgery, joint injections or procedures that permanently change the teeth or bite are not first-line treatment options for TMD.
In many patients, simpler and reversible approaches may be sufficient.
More advanced procedures may be considered only when a specific diagnosis has been established, symptoms cause significant functional impairment and conservative options have been carefully evaluated.
When surgical assessment is required, multidisciplinary planning may involve oral and maxillofacial surgery or other relevant disciplines.
Orthognathic surgery is primarily used to treat skeletal jaw-position discrepancies. It is not the same as TMJ surgery and is not required for every patient with a temporomandibular disorder.
When should jaw symptoms be assessed without delay?
If jaw pain is accompanied by any of the following, a dentist or appropriate healthcare service should be contacted without delay:
- Significant pain, deformity or a sudden change in the bite following trauma
- The jaw becoming locked in an open or closed position
- A sudden and noticeable reduction in mouth opening
- Swelling, redness or fever around the face or jaw
- Pain and restricted movement that prevent eating or drinking
- Sudden numbness, weakness or other neurological symptoms
These findings may require a different assessment from routine TMD symptoms.
Severe or rapidly progressing symptoms should not be managed solely with home-care measures.
What affects the duration and cost of TMD treatment?
Because TMD is not a single disease, the duration of assessment and follow-up is not the same for every patient.
The duration and severity of symptoms, whether findings appear to arise primarily from the joint or muscles, associated health conditions, imaging requirements and the need for multidisciplinary assessment may influence the process.
Cost may vary depending on the scope of the examination, diagnostic records required, planned follow-up, a personalised appliance or the need for coordination with other healthcare disciplines.
A more specific estimate of duration and fees can be provided after clinical assessment has been completed.
A single treatment should not be expected to produce the same outcome for every type of TMD.
TMD assessment in Istanbul, Kadıköy and Caddebostan
At Dr. Esma Kuriş Baştan’s clinic in Caddebostan, the temporomandibular joints, masticatory muscles, jaw movements and bite relationships are evaluated individually.
The clinic can be reached from Kadıköy, Caddebostan, Suadiye, Erenköy, Bostancı, Göztepe, Kozyatağı, Fenerbahçe and surrounding areas.
During the first consultation, the history of symptoms is discussed and a clinical examination is carried out.
Depending on the findings, observation, conservative approaches, an individually designed appliance or referral to another relevant healthcare discipline may be discussed.
The aim is to create a step-by-step plan appropriate to the diagnosis and individual need rather than recommending unnecessary or irreversible procedures.
Frequently asked questions
Does clicking in my jaw mean that I have TMD?
No. Joint sounds without pain or restricted movement can be common and do not always require treatment. Assessment may be appropriate if clicking occurs together with pain, locking or reduced mouth opening.
Can TMJ-related pain be felt around the ear or head?
Pain associated with the temporomandibular joint or chewing muscles may be felt around the area in front of the ear, the temple or the face. However, pain in similar areas may also arise from other health conditions, so diagnosis should not be based on pain location alone.
Will a night guard completely resolve a jaw joint problem?
A night guard or stabilisation splint may contribute to the treatment plan for some patients, but it is not a guaranteed solution for every type of TMD. Suitability, appliance design and duration of use should be determined through clinical assessment.
Is an MRI always required for TMD?
No. For many patients, the history and clinical examination may be sufficient for the initial assessment. MRI or other imaging may be requested when evaluation of internal joint structures is clinically necessary or when another condition is suspected.
Is jaw joint pain caused by stress?
Stress may influence clenching, muscle tension and pain perception in some people, but it is not the sole cause of all TMD symptoms. Jaw pain should be evaluated for dental, joint, muscle and other possible causes rather than being attributed to stress alone.
Are braces required to treat TMD?
Braces are not a routine or automatic treatment for TMD. If there is a separate orthodontic problem, orthodontic treatment may be planned for its own clinical reasons while the joint and muscle symptoms are evaluated separately.
