Do I Have an Earache or a Temporomandibular Disorder?
The symptoms of an ear infection and temporomandibular disorders (TMD) are often very similar, which can lead to confusion. That’s why an accurate differential diagnosis is essential, with close communication between the ENT specialist and the dentist playing a key role.
The temporomandibular joint (TMJ) connects the jaw to the temporal bones of the skull, enabling essential movements such as chewing, speaking, and yawning.
Temporomandibular disorders are functional disturbances that affect this joint and/or the muscles involved in chewing. The causes are usually complex and multifactorial—stress, emotional tension, anxiety, arthritis, bruxism, systemic factors, trauma, poorly adjusted dental treatments, functional overload, joint laxity, osteoarthritis, muscle spasms, among others. Therefore, treatment is ideally managed by a multidisciplinary team.
What Are the Symptoms of Temporomandibular Disorders?
Symptoms can range from facial tension to sharp pain in the preauricular area, along with discomfort in the cheekbones, cheeks, and temples. These symptoms may be temporary or persist for years, and they can affect one or both sides of the face. TMDs are more common in women, especially between the ages of 20 and 40.
Here is a list of symptoms that may indicate you have a TMD:
- Pain or discomfort in the ear, face, TMJ area, and even the neck and shoulders
- Worsening of symptoms when chewing, speaking, singing, or yawning
- Locking of the TMJ, making it difficult to open the mouth normally
- Clicking or popping sounds when opening or closing the mouth or while chewing
- Sudden changes in how your teeth fit together
- Facial swelling
- Headaches, especially in the temples and particularly in the morning
- Dizziness and ear noises (tinnitus)
- A sensation of tooth pain
Diagnosis and Treatment of Temporomandibular Disorders
After a thorough examination and medical history review, the most appropriate treatment for each case will be determined. In some cases, imaging tests such as an MRI or CT scan may be necessary.
Educating the patient about their condition and providing simple daily recommendations is the first step in treatment. Depending on the case, treatment may include occlusal splints (designed based on the specific condition), physiotherapy, or pharmacotherapy.
Sometimes, the way the teeth come together (occlusion) contributes to the dysfunction, and it may be necessary to consider modifying it.
Identifying and controlling aggravating factors is crucial. If conservative treatments fail to relieve symptoms, joint injections or, in more severe cases, TMJ surgery may be indicated.
If you believe you may have a TMD, there are simple recommendations that, when incorporated into your daily routine, can significantly help alleviate your symptoms.
There is increasing evidence of the link between nighttime bruxism and sleep-related breathing disorders, such as snoring and obstructive sleep apnea (OSA).
It has been observed that in some bruxist patients who wear occlusal splints at night, snoring or sleep apnea symptoms may worsen. This can happen with certain splint designs that reduce tongue space or cause the jaw to relax, drop, and move backward, increasing the likelihood of airway collapse.
For this reason, patients who are recommended to use an occlusal or muscle-relaxing splint for bruxism should be evaluated to rule out any underlying respiratory conditions that might worsen with splint use.
After a comprehensive evaluation—including, if necessary, a sleep study—the best treatment approach for each individual will be selected.
