Treatment of the Temporomandibular Joint (TMJ) and Occlusion

Introduction: joint pain that no one connects with the bite

Morning pain when chewing, fatigue of the cheek muscles, clicking right by the ear, sometimes a headache of unclear origin — with such symptoms patients often go first to an ENT specialist or a neurologist. The cause of this pain can be the temporomandibular joint. The question of TMJ treatment and occlusion then regularly comes up in the form: “is my bite to blame, and does it need to be rebuilt?”.

In this article we explain what temporomandibular disorder (TMD) is, what role occlusion really plays, when a splint helps, when physiotherapy, and when prosthetic restoration comes into play. We also show why the order of actions — first diagnosis and reversible treatment, and only then prosthetics — matters for the temporomandibular joint.

Key conclusions in brief

• The temporomandibular joint (TMJ), together with the masticatory muscles, forms a system whose disorders are referred to by the abbreviation TMD (temporomandibular disorder).
• The role of a “bad bite” in causing TMD is today assessed as low — occlusion is rarely the main cause of symptoms.
• Treatment begins with reversible methods: education, physiotherapy and an occlusal splint, not with permanent intervention in the dentition.
• Prosthetic restoration is sometimes needed, but usually after the symptoms have stabilised and where there is a real loss of structures (e.g. advanced tooth wear).

What is temporomandibular disorder (TMD)

Temporomandibular disorder (TMD) is a group of disorders involving the temporomandibular joint itself, the masticatory muscles and the associated structures. It manifests as pain in the area of the ear and cheek, restricted mouth opening, clicking or crepitus in the joint, and tension-type headache. It is not a single disease but a set of symptoms with various causes.

The temporomandibular joint (TMJ) is the connection between the mandible and the temporal bone of the skull — it works with every bite, word and yawn, and its movement is cushioned by the articular disc (a cartilaginous “cushion” between the joint surfaces). Clinically, TMD is most often divided into a muscular form (pain and overload of the masticatory muscles) and an articular form (a problem within the joint itself, e.g. disc displacement). This distinction matters, because the treatment pathway depends on it — muscle pain is managed differently from joint locking.

Temporomandibular disorder is among the common complaints and most often affects adults between the third and fifth decades of life, more frequently women. In many people it runs a mild and transient course, but in some it becomes chronic, affecting the comfort of eating, speaking and sleeping. It is precisely this diversity that means there is no single universal treatment — the management plan has to be matched to the form of the disorder and its cause, not to the name TMD itself.

Does a “bad bite” cause TMD? What the research says

For decades the dominant view was that a faulty bite is the main cause of TMD and that its correction is the basis of treatment. Contemporary reviews of the research challenge this thesis. A narrative review by Kalladka and colleagues (2022) concludes that the role of occlusion as a primary factor in the development of TMD is low to very low, and that good-quality studies demonstrating a cause-and-effect relationship are lacking. An earlier, widely cited review of association studies by Manfredini and colleagues (2017) leads to a similar conclusion.

The relationship can, however, be bidirectional. It is rather that certain forms of TMD may secondarily change the way the teeth meet — the patient then feels that their “bite is slipping”, although this may be a consequence rather than a cause of the joint problem. Distinguishing the direction of the relationship is crucial for accurate treatment: correcting the teeth in response to a joint symptom may entrench the problem instead of solving it.

When TMD does nonetheless have an occlusal basis

There are situations in which occlusion genuinely contributes to the problem: advanced tooth wear, collapse of the vertical dimension, extensive gaps in the posterior segments, or ill-fitting old prosthetic restorations. The issue then is not an “ideal” bite but the lack of stable support for the mandible and muscles. It is precisely these cases that link the treatment of the disorder with prosthetics — we write more about restoration in worn teeth in a separate article on occlusal reconstruction.

That is why the question of TMJ treatment and occlusion has no single answer. In one patient the bite is a background factor; in another, a genuine factor loading the joint and muscles. The task of diagnostics is to determine which group a given case belongs to before any decision on treatment is made. Without this distinction, two opposite errors are easy: rebuilding the bite where it was not needed, or omitting a restoration where the lack of support genuinely sustains the symptoms.

Symptoms of TMD — what patients present with (occlusion and headache)

Among the patients who come to our practice in Wola, Warsaw, we notice that the complaints can be scattered and misleading — it is easy to attribute them to other causes. The most common symptoms of temporomandibular disorder are:

• pain or tension in the facial muscles, worse in the morning (typical of bruxism);
• pain in the jaw joint when chewing, yawning or opening the mouth wide;
• clicking, popping or crepitus in the area of the ear;
• restricted mouth opening, a feeling of the jaw “locking”;
• headache in the temple area and a feeling of a blocked ear — one of the reasons why the topic of occlusion and headache keeps coming up in the practice;
• a sense that the teeth meet “differently” than usual.

Most cases of TMD are chronic and mild, and treatment begins with the least invasive methods. There are, however, situations that require faster consultation.

Seek help urgently if the following symptoms occur:

• sudden locking of the jaw in the open or closed position;
• increasing, severe, one-sided pain;
• swelling, fever or recent facial trauma in the history.

Symptoms, possible cause and treatment pathway — table

The table below is a starting point for a conversation with the dentist, not a ready-made prescription — management depends on the individual diagnosis.

Symptoms	Possible cause	Typical first pathway
Facial muscle pain, morning jaw tension	Bruxism, overload of the masticatory muscles	Education, physiotherapy, occlusal splint
Clicking / popping in the joint	Disc displacement with reduction	Diagnosis, conservative treatment; possibly a splint
Restricted mouth opening, locking	Disc displacement without reduction, inflammation	Urgent consultation, physiotherapy; in selected cases a procedure
Headache, temple area, blocked ear	Tension of the masticatory muscles, bruxism	Control of habits, conservative treatment, splint
A feeling of a “different bite” without clear pathology	Occlusal dysaesthesia	Education and behavioural support; avoid irreversible correction
Worn teeth, collapsed bite, lack of support	Real loss of vertical dimension and occlusal structures	Diagnosis and stabilisation, then prosthetic restoration

When a splint, when physiotherapy, and when a restoration

The occlusal (relaxation) splint — reversible first-line treatment

An occlusal splint is an individually made appliance covering the dental arch, usually worn at night. It relieves the muscles and the joint, protects the teeth from the effects of bruxism and stabilises the position of the mandible — and is at the same time fully reversible. A review by Nassif and colleagues (2023) indicates that splints are a recognised option in the management of TMD when used in combination with conservative methods such as education, biofeedback or physiotherapy. The authors also emphasise that the choice of material and design should be matched to the specific diagnosis.

Physiotherapy and conservative treatment

Reversible methods are the mainstay of TMD treatment. A review by Dinsdale and colleagues (2022) analysing conservative interventions confirms their role in improving chewing function in patients with the disorder. In painful disc displacement with reduction, a network meta-analysis by Al-Moraissi and colleagues (2024) organises the effectiveness of the various methods, supporting an approach based on conservative treatment and physiotherapy before invasive solutions. In practice this means exercises, manual therapy, correction of habits (clenching, chewing gum, mandibular position) and — where needed — pharmacological support.

An important element is also patient education: understanding that many symptoms are linked to tension and overload reduces anxiety and aids improvement. Muscle-relaxation techniques, sleep hygiene and awareness of the daytime tooth-clenching habit can be just as important as the splint itself. Conservative treatment is often underrated because it does not offer a “quick fix”, but it is precisely this that in most patients brings lasting relief without intervention in healthy teeth.

Prosthetic restoration of the occlusion — when it is genuinely needed

In prosthetic practice at Modern Dental & Orthodontics (Klinika MDO) we treat occlusal restoration as a stage after the symptoms have stabilised, not as the first step. Prosthetics comes into play when there is a real, measurable loss of structures — worn teeth, a reduced vertical dimension, gaps in the posterior segments — and not in order to “improve” a subjective impression of the bite. Such a restoration is planned comprehensively within prosthetics, often after a period of splint treatment. It is worth bearing in mind the caution from the guideline on occlusal dysaesthesia (Imhoff et al., 2020): in patients for whom a “bad bite” is a sensation rather than a pathology, irreversible, purely dental treatment should be avoided.

In practice, occlusal restoration in TMD most often combines restoring the lost vertical dimension with an even distribution of the tooth contacts. It may involve onlays, crowns or a full-arch reconstruction — the choice of solution depends on the extent of the damage and the condition of the remaining teeth. The aim is not the aesthetic effect itself but a stable, repeatable occlusion that relieves the joint and muscles. That is why the prosthetic stage is usually preceded by a trial phase (e.g. in a reversible form), to check how the patient tolerates the new vertical dimension before the restoration becomes permanent.

Diagnostics: how the cause is established

An accurate treatment pathway begins with a sound diagnosis, not with guesswork. The examination includes assessing the range of mandibular movement, palpation of the masticatory muscles and joints, assessment of the opening path, and analysis of the occlusion and the wear facets on the teeth. In selected cases — especially where changes within the joint are suspected — imaging can be helpful. The aim is not to find an “ideal” bite but to establish whether a muscular or an articular component predominates, or a genuine deficit of occlusal support. 

TMJ treatment and occlusion: why the order of actions matters

The principle is simple: from the least to the most invasive. First diagnosis and exclusion of other causes of pain, then reversible treatment (education, physiotherapy, splint), and only at the end — and only with clear indications — prosthetic restoration. This order protects the patient from a situation in which the teeth are rebuilt “just in case” while the symptoms do not subside, because their source lay in the muscles or in overload, not in the occlusion itself. The reversibility of the early stages is not caution for caution's sake — it is a safeguard in case the first diagnostic hypothesis turns out to be incomplete.

In this sense, prosthetics and TMJ treatment are not competitors but successive stages. A well- planned occlusal restoration can complete treatment in a patient with a real loss of structures — but carried out too early, before the pain and muscle tension have been brought under control, it risks entrenching the problem in a new form that is harder to correct.

What you can do yourself — home support for treatment

Before you reach a diagnosis and during conservative treatment, many symptoms can be eased on your own. This is support, not a substitute for consultation — with severe, increasing pain or restricted mouth opening, contact a specialist. In most patients simple measures can help:

• Relieve the jaw: avoid wide yawning, biting hard foods and chewing gum; during flare-ups choose a soft diet.
• Mind the rest position: teeth slightly apart, tongue on the palate, lips together — this is the natural arrangement that relieves the joint.
• Watch the daytime tooth-clenching habit; short reminders (a sticky note, a phone alarm) help to break it.
• Apply warm or cool compresses to the painful muscles — warmth relaxes tension, cold soothes acute pain.
• Look after your sleep and reduce stress — emotional tension intensifies bruxism and overload of the masticatory muscles.
• Do not correct your bite on your own and do not grind down your teeth — irreversible changes can entrench the problem.

If, despite such measures, the symptoms do not subside after a few weeks, that is a signal to deepen the diagnostics.

Frequently asked questions

Does a “bad bite” definitely cause TMD?

Not necessarily. Contemporary reviews of the research assess the role of occlusion as a primary cause of the disorder as low to very low. The bite can contribute to the problem where there is a real loss of structures, but in most patients the main role is played by muscle overload, bruxism and behavioural factors, not the shape of the bite itself.

Does TMJ treatment always require rebuilding the teeth?

No. Treatment of temporomandibular joint disorder begins with reversible methods: education, physiotherapy and an occlusal splint. Prosthetic restoration is needed only where there is a real loss of occlusal structures and usually only after the symptoms have stabilised, not as the first step of management.

How long does treatment of TMJ dysfunction take?

It depends on the form and severity. Many muscular cases improve within a few weeks to a few months of conservative treatment. Chronic or articular forms require longer observation. The ultimate duration depends on the individual diagnosis and the response to reversible treatment.

Will an occlusal splint cure TMD?

An occlusal splint relieves the muscles and the joint and protects the teeth, but it works best as part of a broader management approach — together with physiotherapy and correction of habits. The splint alone does not “treat the bite”; it is a reversible method that in many patients clearly reduces symptoms, especially those linked to bruxism.

Can a headache come from the temporomandibular joint?

Yes. Tension of the masticatory muscles and overload of the joint can be a source of temple pain and a feeling of a blocked ear. The topic of “occlusion and headache” keeps coming up in the practice precisely because the complaints are easily mistaken for migraine or an ENT problem. It is worth consulting them with a clinician familiar with TMD diagnostics.

Which specialist should I see?

The starting point is a dentist who deals with temporomandibular disorders; they often work with a dental physiotherapist. The diagnosis covers examination of the joint, muscles and occlusion and, where needed, imaging. Only on this basis is it decided whether a splint, physiotherapy or a prosthetic restoration is needed.

Can TMD go away on its own?

Some mild, transient symptoms do indeed resolve spontaneously, especially when they resulted from temporary overload. If, however, the complaints recur, intensify or restrict mouth opening, it is not worth waiting — early reversible treatment is more effective and reduces the risk of the problem becoming entrenched.

What can I do at home to ease TMJ pain?

Relieving the jaw helps: a soft diet, avoiding gum and wide yawning, warm or cool compresses on the muscles, and consciously relaxing clenched teeth during the day. Sleep and reducing stress also matter. This is support for treatment, not a substitute for a diagnosis — with severe or increasing pain, consult a specialist.

Is clicking in the joint dangerous?

Usually not. Painless clicking without restricted mouth opening is common and in itself rarely requires aggressive treatment. It becomes concerning only when the clicking is accompanied by pain, jaw locking or increasing restriction of movement — then it is worth having a specialist assess the condition of the articular disc.
