Temporomandibular disorders is an umbrella term to describe conditions that cause dysfunction of jaw joint and pain in the jaw joint and the muscles that control the movement of the jaw joint.
The exact cause of temporomandibular joint disorder is challenging to determine. A combination of several factors, such as genetic injury and arthritis, is considered responsible. In this article, we will discuss temporomandibular arthritis in detail and Ayurveda treatment for the same. However, let us discuss a few facts on temporomandibular joint disorders.
Facts on Temporomandibular Joint Disorder

Types of Temporomandibular joint arthritis
- Infectious Temporomandibular Arthritis– Infectious temporomandibular arthritis is an infection of the temporomandibular joint. It results from a haematogenous spread of blood borne organisms or direct extension of the adjacent infection. The Jaw area is inflamed. Jaw movement is painful and limited. In the early stages of the disease, the x-ray results are negative, but later on, may show bone destruction. To prevent permanent damage to the jaw joint, it is important to make an early diagnosis.
- Temporomandibular Joint Osteoarthritis – Temporomandibular joint osteoarthritis mostly affects people who are above 50 years. The patient mostly complains of grating, stiffness, or mild pain. The involvement of the joint is generally bilateral. The X-ray or CT scan report shows lipping or flattening of the condyle that suggests dysfunctional changes.
- Traumatic Temporomandibular Joint Arthritis – Rarely an acute injury causes TMJ arthritis. The symptoms include tenderness, pain, and limitation of motion. Diagnosis is made primarily on the history of trauma. In most cases, the X-ray result is negative, except when there is hemorrhage or intra-articular edema that widens the joint space.
- Temporomandibular Joint Rheumatoid Arthritis – About more than 17% of adults and children with rheumatoid arthritis are affected by TMJ disorder. However, usually, the last joints are involved. It leads to swelling, pain, and limited movement. In children, there is face deformity and mandibular growth disturbance. The X-ray report usually negative in the earlier stages but later on show bone destruction.
- Secondary Degenerative Temporomandibular Arthritis – This type of temporomandibular joint arthritis develops in people between 20 to 40 years of age. It follows trauma or occurs in people with persistent myofascial pain syndrome. The characteristic feature of this type of arthritis is the limited opening of the mouth, joint tenderness, and unilateral pain. The diagnosis is made based on the x-ray that shows lipping, spurring, erosion, or flattening of condylar.

Risk Factors for TMJ Disorders
Risk factors that increase the chances of developing TMJ disorders include:
- Various types of arthritis, such as osteoarthritis or rheumatoid arthritis
- Jaw injury
- Long-term clenching or grinding of teeth
- Certain connective tissue diseases that may affect the temporomandibular joint.
How TMJ disorder Occurs
The temporomandibular joint is a complex structure containing bones, muscles and tendons that connects the jaw to the skull and acts as a sliding hinge. The TMJ is made by the mandibular condyle and glenoid fossa of the temporal bone that is a fibrous articular disk that acts as a cushion between the joint surfaces. On each side of the jaw, there is a joint. If it is damaged or injured, it leads to localized pain disorder and is termed as a temporomandibular joint syndrome or mandibular temporal disorder. TMJ disorders is multifactorial in origin, but most of the problem is related to internal disarrangements within the joints itself. This causes disturb movement of the jaw.
Painful TMJ disorder occurs due to the following reasons:
- The disk moves out or erodes of its proper alignment
- Arthritis damages the joint’s cartilage
- An impact or blow damages the joint.
