TMD: what it is, most common symptoms and how it can be treated

Temporomandibular Disorder (TMD) is a condition that affects the temporomandibular joint (TMJ), responsible for connecting the jaw to the skull and allowing movements such as opening and closing the mouth, chewing and speaking.
Although often associated only with “clicking” in the jaw, TMD may present through pain, muscle tension, limited movement and even frequent headaches.
It is common for patients to search online with questions such as “how to treat TMD”, in an attempt to find a solution. However, TMD is not a single condition and does not have one universal cause — treatment always depends on a detailed functional diagnosis.
Understanding what is causing the dysfunction is the first step in defining the most appropriate approach.
What is TMD (Temporomandibular Disorder)?
TMD refers to a group of alterations affecting the temporomandibular joint (TMJ), the chewing muscles and associated structures.
The TMJ works like a complex hinge, allowing rotational and translational movements. For it to function correctly, balance is required between the joint, muscles and occlusion (the way the teeth fit together).
When there is imbalance — whether due to excessive muscle tension, bruxism, bite changes or emotional factors — pain, inflammation or functional limitation may arise.
It is important to distinguish between an occasional symptom (such as an isolated click without pain) and an established dysfunction that compromises function and the patient’s wellbeing.
What are the most common symptoms of TMD?
Many patients initially experience only occasional discomfort or minor clicking sounds, dismissing the symptoms until they become more frequent or intense. The combination of muscle pain, joint noises, headaches and changes in jaw mobility suggests a functional imbalance that should be assessed in an integrated way.
Early identification of these symptoms allows intervention before overload of the TMJ and chewing muscles progresses into more complex or chronic conditions.
Pain in the jaw and face
The pain may be muscular, joint-related or mixed. It is often described as a feeling of pressure, fatigue or pain when chewing. It may radiate to the face, temples or ear region.
Clicking or noises when opening and closing the mouth
Clicking may occur due to alterations in the articular disc of the TMJ. When not associated with pain or functional limitation, it may not be concerning. However, if accompanied by pain or locking, it should be assessed.
Headaches and neck tension
The chewing muscles are closely linked to the cervical region. Excessive tension in the jaw muscles may contribute to tension headaches and discomfort in the neck and shoulders.
Limitation or deviation when opening the mouth
Difficulty fully opening the mouth, a feeling of locking or deviation of the jaw during movement are signs that may indicate joint dysfunction.
What causes TMD?
It is also important to note that, as TMD is a multifactorial condition, symptoms may appear intermittently. It is common for periods of greater discomfort to be followed by times when pain decreases or temporarily disappears. This fluctuation does not necessarily mean that the problem has been resolved.
Often, the temporomandibular joint and associated muscles remain overloaded, with compensatory mechanisms only temporarily reducing the clinical signs. For this reason, even symptoms that seem to “come and go” should be assessed within a broader functional context, in order to identify the source of the imbalance and prevent progression into more persistent conditions.
Bruxism and muscle tension
Grinding or clenching the teeth (bruxism), especially during sleep, overloads the muscles and joints. Over time, this overload may generate pain, inflammation and tooth wear.
Changes in occlusion
An unstable or misaligned bite may create inadequate contact points between the teeth, leading to muscular and joint compensations.
Stress and emotional factors
Situations of anxiety and stress increase involuntary muscle activity, intensifying tension in the jaw region.
Trauma or parafunctional habits
Facial trauma, nail biting, chewing always on the same side or constantly resting the chin on the hand are habits that may contribute to functional imbalance.
TMD: how can it be treated?
When people ask “how to treat TMD”, it is important to clarify that there is no standard solution applicable to all cases.
Treatment depends on the origin of the dysfunction and must always be tailored to each case.
Functional diagnosis
Treatment of TMD always begins by understanding how the joint, muscles and occlusion are functioning together. At Dr Cláudio Alferes’ practice, functional diagnosis does not focus only on isolated symptoms, but on identifying the pattern of imbalance causing the pain or limitation.
The assessment includes detailed analysis of jaw movements, muscle palpation, occlusal study and, when clinically indicated, use of CBCT imaging to assess the anatomy of the TMJ.
Based on this data, an individualised study is carried out to define a therapeutic strategy adapted to each patient’s functional profile — avoiding generic approaches and focusing on the cause of the problem.
Deprogramming splints
Deprogramming splints are customised devices used to reduce muscle hyperactivity and reorganise jaw position, decreasing overload on the temporomandibular joint.
They may not “cure” TMD in isolation, but when correctly indicated and clinically monitored, they can help stabilise function, relieve symptoms and allow a more precise assessment of the relationship between occlusion, muscles and the joint.
Orthodontic treatment
Orthodontic treatment consists of correcting tooth positioning and the relationship between the upper and lower jaws through fixed braces or clear aligners.
When there are dental misalignments or an unstable bite contributing to muscular and joint overload, orthodontics may help redistribute forces, improve occlusion and promote a more stable functional balance over time.
Physiotherapy and multidisciplinary approach
Specialised physiotherapy may help reduce muscle tension and improve joint mobility. In some cases, an integrated approach with other health disciplines is essential.
Management of bruxism and behavioural factors
Strategies to control stress, improve sleep quality and correct parafunctional habits are part of the overall approach.
When should you seek specialist assessment?
You should consider an assessment if you experience:
Persistent jaw or facial pain;
Clicking accompanied by pain or limitation;
Frequent headaches associated with jaw tension;
Difficulty opening or closing the mouth;
A feeling of tooth wear or muscular fatigue on waking;
Pain or tension in the neck area.
The earlier the diagnosis, the simpler the intervention tends to be.
Can TMD be cured?
TMD is a functional condition that can have a significant impact on quality of life. Although many people search for “how to treat TMD”, the real solution lies in understanding the specific cause of the problem and defining a personalised treatment plan.
A specialist assessment makes it possible to identify the origin of the dysfunction and establish the most appropriate approach to restore comfort, stability and function.
If you have symptoms compatible with TMD, book a functional assessment consultation to obtain an accurate diagnosis and a treatment plan adapted to your case.
