Pain in the face when opening the mouth

Facial pain when opening the mouth can arise from various causes, such as impacted wisdom tooth inflammation, temporomandibular joint disorder, or parotitis. Detailed explanations are as follows:

1. Wisdom Tooth Inflammation

If a patient has a wisdom tooth that grows in an improper position and becomes irritated, inflammation may occur. Patients often experience facial pain when opening their mouths. This condition is usually accompanied by swollen and painful gums. In severe cases, patients may take medications such as amoxicillin capsules or levofloxacin tablets under medical guidance to relieve symptoms. After the inflammation subsides, the wisdom tooth can be surgically removed at a hospital.

2. Temporomandibular Joint Disorder

This disorder may develop when there is abnormal bite alignment. It commonly occurs in young and middle-aged adults. When one side of the temporomandibular joint is affected, in addition to facial pain upon opening the mouth, clicking or popping sounds may also be present. If the condition is mild, it can be relieved with local heat application. For more severe cases, medications such as flurbiprofen gel patches or diclofenac sodium sustained-release tablets may be used for treatment.

3. Parotitis (Salivary Gland Inflammation)

The parotid glands are located on both sides of the earlobes. When inflammation occurs in the left parotid gland, opening the mouth may stretch local nerves, causing facial pain. In such cases, patients may take medications like Pudilan Xiaoyan tablets or Niuhuang Jiedu tablets as directed by a physician to alleviate symptoms.

Besides the above, this symptom may also be related to gingivitis, submandibular lymphadenitis, or myofascial inflammation. It is recommended that patients seek timely medical evaluation and receive appropriate treatment under professional guidance when experiencing facial pain during mouth opening.
