Connection Between Thyroid and TMJ
Weight gain, muscle weakness, and fatigue, among other symptoms, indicate that your thyroid gland is out of whack. But did you know that the thyroid gland could affect your oral health? Did you also know that there is a connection between your thyroid and the temporomandibular joint (TMJ)?
You might be battling jaw pain which could be debilitating and can make simple tasks such as chewing, talking, and yawning daunting tasks. What could be worse is you not having a clue what is causing the jaw pain. Therefore, seeking our TMJ providers near you could be the best thing to do.
The thyroid has many functions, and if it is not at its best, your TMJ could be affected. That’s why our Anchorage dentist encourages our patients always to seek immediate care.
In any case, let’s unpack a thing or two about TMJ, the thyroid, and their connection.
TMJ, In a Nutshell
The temporomandibular joint is a mouthful, but the joint is a vital joint that is located on either side of your jaw. It functions as a sliding hinge, linking your lower jawbone to your skull. The TMJ enables the jaw’s side to side and up and down movements to facilitate various actions such as talking, yawning, laughing, and eating.
The TMJ could be injured or inflamed to cause a condition known as temporomandibular joint disorder (TMD). You might have come across people mistakenly referring to the disorder as TMJ. TMJ is the acronym for the joint and not the disease.
Signs that your TMJ could be at whack are:
- Popping sounds
- Stuck jaws
- Trouble chewing
- Difficulty opening your mouth
- Swelling on both sides of the face
- Uncomfortable bite
- Tenderness in your face, neck, shoulders and jaw
About the Thyroid
The thyroid gland is a tiny organ with several functions and is located in your neck, wrapped around your trachea (windpipe). The thyroid has a butterfly shape, smaller in the middle and has two broad wings that extend on either side of your throat.
Even though the thyroid is a tiny organ, it releases various hormones essential for controlling several vital functions in your body.
When the thyroid is not working correctly, your whole body will be affected. If the body secretes too much thyroid hormone, you will develop hyperthyroidism. If the converse happens and your body produces less of the hormone, you will develop hypothyroidism. In both cases, your body will be affected negatively.
Thyroid disease refers to a scenario where your thyroid cannot synthesize the right amount of hormones to keep your body functioning well. Thyroid disease affects anyone, including kids, men, women, the elderly, and teenagers.
How Are They Linked?
The thyroid hormones are vital for skeletal development, linear growth, and the maintenance of adult bone mass. The adult bones are maintained by being remodelled to give the skeleton a chance to grow and repair. Some of the bones will be dissolved to replace them with new bones.
The intricate balance of bone dissolution and replacement at several molecular levels could be disrupted if there is under-or overproduction of the thyroid hormones.
Hyperthyroidism (high levels of thyroid hormones) can result in rapid bone loss, and the new bone might not be as strong as the older bone. If this continues to happen, it might lead to osteoporosis.
Hypothyroidism (low levels of thyroid hormones) can result in slow bone metabolism, meaning the new bone might not form on time. Therefore, there could be a chance that your bones might wear more than usual.
So, if these issues occur, your TMJ could be affected, and it might explain why you might be experiencing jaw pain and other symptoms related to TMD.
What Treatments Options Are Available?
The brilliant thing to do would be to visit our Anchorage dentist to get your TMJ checked. At least you may receive the help you need to help you deal with symptoms associated with TMD. Some of the treatments that you will receive include:
- Anti-inflammatories and pain medication to reduce the inflammation and pain
- Tricyclic antidepressants to control bruxism and alleviate pain
- Muscle relaxants to deal with muscle spasms
- Mouthguards or oral splints to help jaw movement
- Injections
- Surgery
However, if TMD is caused by thyroid disease, the best course of action would be to deal with the thyroid issue while using the treatments dealing with TMD.

FAQs
Thyroid disorders may influence muscle tone, inflammation, and joint sensitivity. In some individuals, these systemic changes can contribute to jaw discomfort or tension that resembles TMJ symptoms. A proper medical and dental evaluation helps determine whether thyroid imbalance may be a contributing factor.
Symptoms such as muscle stiffness, fatigue, joint discomfort, and headaches may overlap between thyroid disorders and TMJ dysfunction. Because these symptoms are not specific to one condition, clinical assessment is necessary to identify whether jaw pain is related to bite mechanics, muscle strain, or systemic causes.
No. While stress-related clenching is common, TMJ disorders can also result from arthritis, bite imbalance, injury, or underlying medical conditions. Identifying the root cause is essential before starting treatment to ensure appropriate care.
Thyroid hormones regulate metabolism and muscle function. When levels are abnormal, muscle stiffness, fatigue, or weakness may occur. In various cases, this can affect the muscles responsible for jaw movement. A dentist in Anchorage, AK, evaluates jaw mechanics and muscle tenderness to determine whether symptoms are related to joint dysfunction rather than systemic imbalance.
Managing thyroid levels may reduce systemic symptoms such as muscle fatigue or inflammation. However, TMJ dysfunction often involves mechanical factors like bite alignment or joint stress. Even when thyroid disease is controlled, a separate dental evaluation may be necessary to address persistent jaw discomfort.
Diagnosis begins with reviewing symptoms, medical history, and jaw function. Your provider evaluates bite alignment, muscle tenderness, and joint movement. Imaging may be considered if structural issues are suspected. Coordinating care with your physician ensures systemic conditions are managed alongside dental findings.
If jaw discomfort persists, limits movement, or worsens despite thyroid treatment, a dental evaluation is appropriate. Searching for a dentist near me allows you to arrange an assessment of joint function and rule out localized causes. Early evaluation helps prevent worsening strain.
Autoimmune thyroid issues, such as Hashimoto’s disease or Graves’ disease, may be associated with systemic inflammation. In some individuals, inflammatory changes can affect joints or muscles, including those involved in jaw movement. However, TMJ disorders are often multifactorial and may involve bite imbalance, muscle tension, or degenerative changes. A comprehensive evaluation helps determine whether symptoms are primarily dental, systemic, or a combination of both.
A clinical exam evaluates the jaw range of motion, joint sounds, muscle tenderness, and bite alignment. If symptoms are localized to the jaw joint and worsen with chewing, TMJ dysfunction may be suspected. Systemic symptoms such as widespread fatigue or generalized muscle pain may suggest broader medical involvement. Coordinated communication between your dentist and physician helps clarify the underlying cause.
Treatment depends on identifying the primary source of symptoms. Thyroid disorders are managed medically by a physician. If TMJ dysfunction is confirmed, treatment may include a nightguard, bite adjustment, or muscle relaxation strategies. Addressing both systemic and mechanical factors improves comfort and helps prevent ongoing joint strain. Anchorage Dental Arts recommends a comprehensive evaluation when symptoms overlap.
