Introduction
Pain near the ear and difficulty opening the mouth may be caused by wisdom tooth infection, temporomandibular joint disorder (TMJ), stomatitis, periodontitis, parotitis, or other conditions. The exact cause must be determined through medical evaluation by a doctor. If you are experiencing these symptoms, especially if the pain is severe or persistent, it is recommended to consult a healthcare professional as soon as possible for an accurate diagnosis.

Generally, ear root pain accompanied by difficulty opening the mouth may be caused by wisdom tooth infection, temporomandibular joint disorder (TMD), stomatitis, periodontitis, mumps, and other reasons. A detailed analysis is as follows:

1. Wisdom Tooth Infection

Wisdom teeth are large molars located at the very back of the mouth. They sometimes cause problems such as infection or inflammation, which can lead to pain, swelling, and difficulty opening the mouth. In necessary cases, extraction may be required.

2. Temporomandibular Joint Disorder (TMD)

TMD is one of the common causes of ear root pain and limited mouth opening. This condition is usually associated with muscle tension or inflammation around the temporomandibular joint. Applying heat can help relax the jaw muscles and relieve discomfort.

3. Stomatitis

Stomatitis refers to inflammation of the oral mucosa, which may result from infections, injuries, excessive friction, or other factors. It can cause oral discomfort and pain, sometimes accompanied by ear root pain. Under medical guidance, medications such as cefdinir capsules or cefixime tablets may be used to alleviate symptoms. Additionally, maintaining a light diet is recommended.

4. Periodontitis

Periodontitis is an infection and inflammation of the tissues surrounding the gums, which may cause mouth pain, gum bleeding, and discomfort, and may also affect the function of the temporomandibular joint. Under medical supervision, treatment may include medications such as minocycline hydrochloride capsules or ibuprofen tablets.

5. Mumps

Mumps is an infection or inflammation of the parotid glands, which may cause pain in the temporomandibular region and difficulty opening the mouth. Treatment may involve antiviral medications such as ribavirin tablets or acyclovir tablets, as prescribed by a physician.

The exact cause must be determined through medical evaluation. If you are experiencing these symptoms—especially if the pain is severe or persists for a long time—it is advisable to consult a healthcare professional promptly for an accurate diagnosis.
