Introduction

In general, pain behind the jaw may be related to temporomandibular joint disorders, muscle fatigue, submental lymphadenitis, temporomandibular joint arthritis, pericoronitis of wisdom teeth, and other causes. It is recommended to seek medical attention promptly and follow the doctor's guidance for treatments such as general care and medication. In daily life, regular dental check-ups should be conducted to help maintain oral health.

Generally, pain behind the chin may be related to temporomandibular joint disorders, muscle fatigue, submental lymphadenitis, temporomandibular joint arthritis, pericoronitis of wisdom teeth, and other causes. It is recommended to seek timely medical attention and adopt general treatments, medication, and other treatment methods under a doctor's guidance. Detailed explanations are as follows:

1. Temporomandibular Joint Disorders

Poor occlusion and dysfunction of the masticatory muscles can lead to temporomandibular joint disorders, causing inflammation within the joint and subsequent pain, which may radiate to the area behind the chin. It is recommended to maintain good occlusal relationships and avoid chewing on one side only.

2. Muscle Fatigue

Extended talking, chewing hard objects, or overusing the jaw can cause muscle fatigue around the chin, leading to pain. One should maintain proper posture and avoid prolonged jaw use in daily life.

3. Submental Lymphadenitis

Submental lymphadenitis is usually caused by inflammatory infections in areas such as the oral cavity and throat. The inflammation may affect the area behind the chin, causing pain. It is often accompanied by symptoms such as lymph node swelling, fever, and fatigue. Medications such as Amoxicillin Capsules, Cefradine Capsules, and Roxithromycin Dispersible Tablets may be used under a doctor's advice for treatment.

4. Temporomandibular Joint Arthritis

Temporomandibular joint arthritis may be caused by trauma, infection, or other factors. Inflammation irritates the joint and surrounding tissues, causing pain behind the chin. Symptoms usually include limited mouth opening, difficulty chewing, and joint clicking. Follow medical advice to use medications such as Ibuprofen Sustained-Release Capsules, Diclofenac Sodium Sustained-Release Tablets, and Indomethacin Enteric-Coated Tablets to alleviate symptoms.

5. Pericoronitis of Wisdom Teeth

Pericoronitis of wisdom teeth refers to an inflammatory infection of the soft tissues surrounding the crown of a partially erupted or impacted wisdom tooth. The inflammation may spread to the area behind the chin, causing pain. Common symptoms include redness and swelling of the gums, pain, and restricted mouth opening. Treatment typically involves following medical advice to use medications such as Metronidazole Tablets, Ornidazole Dispersible Tablets, and Tinidazole Capsules.

In daily life, maintaining good living habits and undergoing regular dental checkups can help preserve oral health.
