What is causing the pain in the jawbone

In life, some patients often feel tooth and jaw pain when eating. In severe cases, they cannot even control the opening and closing of their mouths, do not want to eat, and feel pain in the entire nerves and in the head. However, everyone thinks it is because they eat too much and do not take it seriously. So what exactly is causing the tooth and jaw pain? The editor will introduce it to you below.

Jaw joint pain is a manifestation of temporomandibular joint disorder. Temporomandibular joint disorder syndrome is one of the common diseases of the oral and maxillofacial region. It is the most common disease among temporomandibular joint diseases. In recent years, the name widely accepted internationally is temporomandibular joint disorder. Temporomandibular joint disorder syndrome does not refer to a single disease, but a general term for a group of diseases whose causes are not yet fully understood and have the same or similar clinical symptoms. The cause of the disease has not yet been fully elucidated. Most scholars have proposed factors related to the onset of the disease based on experimental and clinical studies, and all believe that the disease is a multifactorial disease.

It is generally believed to be related to the following factors:

1. Psychosocial factors: Patients often have mental symptoms such as anxiety, irritability, mental tension, excitability and insomnia. In some patients, there is an obvious causal relationship between mental and emotional factors and the onset of the disease. In chronic and protracted patients, the influence of mental factors on the recurrence of symptoms can also be found.

2. Occlusal factors: Clinical examination of TMD patients often reveals obvious occlusal factors, including interference, premature cusp contact, severe lockbite, deep overbite, majority of posterior teeth missing, and excessive wear of the occlusal surfaces resulting in a low vertical distance.

3. Immune factors: Immunological studies have shown that the main components of articular cartilage, such as collagen polysaccharides and chondrocytes, are antigenic. Because articular cartilage is wrapped in matrix, it is isolated from the vascular system from embryo to adult, becoming a closed antigen that cannot be recognized by the body's immune system. Related experimental studies have shown that TMD also involves cellular immunity.

4. Excessive load on joints: Moderate weight-bearing is necessary and important for maintaining the normal structure, function and physiological remodeling of joints. However, excessive weight bearing beyond physiological limits can cause degenerative changes or even damage to the joints.

5. Joint anatomical factors: From a functional point of view, the temporomandibular joint and jaw have become more flexible as humans evolve to adapt to more complex jaw movements for speech and facial expressions. Because of this, from an anatomical point of view, the corresponding joints, muscles and ligaments become significantly weakened, and the load-bearing capacity of the joints decreases. This increase in the type, flexibility, and range of joint motion in humans is a potential threat to the anatomically weakened temporomandibular joint.

6. Other factors: Cold stimulation of the joint area, muscle dysfunction caused by bad posture and affecting the normal position of the mandible and condyle are also factors that induce temporomandibular joint disorder.
