Jaw pain while chewing that has lasted for a month could be related to issues with the temporomandibular joint (TMJ), dental problems, or muscle strain. Since this pain is persistent, it is important to have it evaluated by a dentist or an oral and maxillofacial specialist to determine the exact cause and receive appropriate treatment.

• Avoid hard or chewy foods that may worsen the pain.
• Apply warm compresses to the jaw area to help relieve discomfort.
• Monitor for any additional symptoms like swelling, clicking sounds, or difficulty opening the mouth.

If the pain worsens, is accompanied by fever, or you experience difficulty swallowing or breathing, seek urgent medical attention. Otherwise, please consult a dentist or oral surgeon for a thorough examination and tailored care.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
