Hello, most of the dental pain can be obtained by a detailed history and examination. It depends on location, type, frequency and duration, onset, response to heat or cold, severity and area of radiation. Certain tests like pulp sensitivity test, percussion test, mobility test, palpation, and radiographic examination. If the pain is short, sharp, shooting pain it could be caries, dentine exposure, split cusp, fractured tooth, and gingival recession, trigeminal neuralgia. If the pain is dull, throbbing and persistent, it may be due to caries food impaction, pericoronitis , acute necrotizing ulcerative gingivitis, temparomandibular disorders or even maxillary sinusitis. Treatment depends on the cause. It is either root canal therapy or tooth removal. Periapical inflammation leads to cellulitis of the face that results in extensive edema and pain. Antibiotics should be prescribed only whenever it is required. Antibiotics should be limited to fever, malaise, lymph nodes involvement, suppressed immune system, cellulitis or a rapid onset of severe infection. If pus is present, it should be drained out. Paracetamol or non-steroidal anti-inflammatory drugs is recommended to relieve the pain. I would suggest you to consult your dentist for a detail examination and appropriate treatment. Thank you.
