Jaw pain and bruxism: what TMJ physiotherapy can do

Do you notice a clicking sound when you open or close your mouth? Do you have jaw pain or discomfort around the ear area that worsens in the morning? Does your partner tell you that you grind your teeth at night? If you identify with any of these situations, it is very likely that you have some form of temporomandibular joint dysfunction, known as TMJ, and physiotherapy could be the solution you are looking for.

At Rincón Salud, we have a specialised TMJ physiotherapy service where we treat jaw dysfunctions using advanced manual techniques, state-of-the-art technology and an approach that considers the relationship between the TMJ and the rest of the musculoskeletal system.

What is the temporomandibular joint?

The temporomandibular joint connects the mandible (the mobile lower jawbone) to the skull, specifically to the temporal bone. There are two joints, one on each side of the face, right in front of each ear. These are the joints we use when talking, chewing, yawning or swallowing, making them some of the most active and frequently used joints in the entire body.

Between the two bones of the joint lies a small fibrocartilage disc that acts as a shock absorber and enables smooth gliding of the jaw. When this disc becomes displaced, when the muscles that move the jaw become overloaded, or when inflammation occurs in the joint, temporomandibular dysfunction develops alongside all its symptoms.

What many people do not know is that the TMJ does not function in isolation. It is closely linked to the muscles of the neck, shoulders and cervical spine, overall body posture, and the nervous system. That is why the physiotherapeutic approach to the TMJ goes far beyond "treating the jaw".

Causes of jaw pain and TMJ dysfunction

Temporomandibular dysfunction power rarely stems from a single cause. In most cases, it is the result of a combination of several factors that reinforce each other:

Bruxism: the great silent enemy of the TMJ

Bruxism is the involuntary habit of clenching or grinding teeth, usually during sleep, although it can also occur during the day in situations of stress or intense concentration. It is far more common than people think: it is estimated to affect between 8% and 10% of the adult population, and many people have it without realising it.

The problem bruxism poses for the TMJ is twofold: on the one hand, it overloads the masticatory muscles (masseter, temporalis, pterygoid), generating chronic tension that ultimately irritates the joint; on the other hand, repeated forced contact between teeth can wear down dental surfaces and alter occlusion, which in turn alters joint mechanics.

Dental malocclusion

When teeth do not fit together properly upon closing the mouth — whether due to the position of the teeth themselves, the relationship between the jaws, or ill-fitting dental prostheses — the TMJ must make a constant compensatory effort to find a stable closing position. In the long term, this effort creates muscle tension and joint overload.

Stress and emotional tension

Stress is one of the most significant triggers of TMJ dysfunction, as well as one of the most underrated. In response to emotional tension, it is very common for the body to accumulate stress in specific muscle groups, with the chewing muscles being a primary target. A clenched jaw, constant tooth contact and a tense neck are physical responses to stress that, if maintained over time, end up damaging the joint.

Sustained postures and prolonged screen time

Spending long hours with a forward head posture in front of a computer or looking at a mobile phone alters the alignment of the entire cervical spine and, with it, the resting position of the jaw. There is a very direct biomechanical relationship between cervical posture and the TMJ: when the head projects forward, the jaw tends to open and the chewing muscles work under unfavourable mechanical conditions.

Trauma

A blow to the jaw, a fall, a complicated dental extraction or even keeping the mouth wide open during a prolonged dental procedure can trigger TMJ dysfunction that, if left untreated, can become chronic.

Most common symptoms of TMJ dysfunction

Temporomandibular dysfunction can present in many ways, which sometimes makes diagnosis difficult when it is not initially considered:

• Pain in the jaw, ear area or face, which can be constant or appear only when chewing or talking
• Clicking, popping or crepitus noises when opening and closing the mouth
• Difficulty or limitation when opening the mouth fully
• Jaw locking (a feeling that it "catches" when opening or closing)
• Tension headaches, especially in the temples or forehead
• Associated neck and shoulder pain
• Earache or a feeling of pressure without an otological cause
• Tinnitus (ringing in the ears) in some cases
• Visible dental wear, especially on the incisal edges
• A feeling that the teeth do not bite together properly

It is worth noting that many of these symptoms — headaches, ear pain, tinnitus — are frequently misattributed to other causes, which is why TMJ dysfunction is a condition that often takes time to be correctly diagnosed.

How can TMJ physiotherapy help?

Physiotherapy is one of the first-line treatments for temporomandibular dysfunction, backed by solid scientific evidence regarding its effectiveness for both pain relief and jaw function. At Rincón Salud, we apply a comprehensive approach that includes:

Specialised manual therapy

Manual therapy is the core of physiotherapeutic TMJ treatment. It includes techniques applied both outside and inside the mouth (using gloves), always prioritizing patient consent and comfort:

• Joint mobilisation: passive and assisted movements of the jaw to restore range of opening, normalise joint mechanics and reduce pain.
• Soft tissue techniques: work on the chewing muscles (masseter, temporalis, medial and lateral pterygoid) to release tension, reduce myofascial trigger points and improve local circulation.
• Intraoral therapy: specific techniques applied inside the mouth that allow direct access to the medial pterygoid and retrodiscal tissue to release tension that is inaccessible from the outside.
• Cervical treatment: given that the TMJ and the cervical spine are closely linked, treatment always includes an assessment and address of the cervical region, suboccipital area and neck musculature.

Personalised therapeutic exercises

In addition to in-clinic treatment, patients receive a home exercise programme tailored to their specific case. These exercises aim to:

• Improve jaw coordination and motor control
• Strengthen stabilising muscles in cases of hypermobility
• Stretch tense and overloaded muscles
• Correct postural habits that perpetuate the problem
• Re-educate the resting position of the tongue and jaw

Consistency with home exercises is as important as in-clinic treatment to achieve lasting results.

Applied technology: INDIBA and other techniques

At Rincón Salud, we complement manual therapy with advanced technology when required by the case. Radiofrequency energy via capacitive and resistive transfer (INDIBA) is particularly useful in TMJ dysfunction because it:

• Reduces joint and muscle inflammation in a non-invasive way
• Relieves pain in the acute phase
• Accelerates tissue recovery in cases of chronic inflammation
• Improves joint mobility, facilitating subsequent manual work

We can also use dry needling on trigger points within the masticatory muscles when indicated, or neuromodulation techniques for chronic pain.

Coordination with the dentist or orthodontist

In many cases of TMJ dysfunction, working in coordination with a dentist is essential. When the origin or persistence of the problem has a significant occlusal component — malocclusion, severe bruxism, poorly fitted prostheses — physiotherapy alone will not resolve the underlying issue. Collaboration between physiotherapist and dentist enables a coherent treatment plan: the physiotherapist addresses the muscular and joint component, while the dentist works on occlusal factors using night guards or other solutions according to the case.

At Rincón Salud, we have a multidisciplinary team that facilitates internal coordination, saving the patient from having to manage communication between different professionals across different centres.

How many TMJ physiotherapy sessions do I need?

This is one of the most frequent questions, and the honest answer is: it depends. There is no standard number of sessions that applies to every case.

For mild or recent dysfunctions with a good response to treatment, between 6 and 10 sessions may be sufficient. In chronic cases with years of evolution, significant maintaining factors (active bruxism, malocclusion, high stress) or recurrent locking, treatment may take longer and include maintenance phases.

What we can say with certainty is that the earlier treatment begins, the better and faster the results will be. TMJ dysfunction tends to become chronic and expand its area of pain radiation over time: what starts as an annoying click can end up as a locked jaw, a chronic headache or persistent neck muscle tightness.

During your first visit, we carry out a thorough assessment and explain our estimated treatment plan for your specific case with total transparency.

TMJ Physiotherapy at Rincón Salud

Our TMJ physiotherapy service stands out due to several key aspects that make a real difference in outcomes:

A team of physiotherapists with specific training in craniofacial therapy and TMJ, not simply general physiotherapists who "also treat the jaw". Specificity matters, because the TMJ requires techniques and knowledge that go far beyond conventional musculoskeletal physiotherapy.

A holistic approach that is not limited to the joint itself, but includes the cervical spine, shoulders, posture and maintaining factors such as stress or parafunctional habits.

Advanced technology (INDIBA, electrostimulation, dry needling) integrated into the treatment protocol when it adds genuine value to the case.

Coordinated work with the rest of the centre's specialties — dentistry, general medicine, neurology — for cases requiring a multidisciplinary approach.

We have clinics in Torre del Mar and in La Rosaleda (Málaga city) so you can always find the most convenient location for you.
