<s>[INST] Hi my name is sarah and i have a question the back of my mouth started hurting and i could barley open it and i went to the hospital and they said it look like there was tissue building up around my wisdom teeth and they gave me pinicillin and some pain medication and today it feels better but i looked at it and there is a hole in the back of my gum??? idk if its because its healing or getting worst??? [/INST] Hello, Thanks for consulting Chat Doctor, Read your query, as you have pain in back of gum this can be due to eruption of wisdom tooth may be there is pain due to impacted wisdom tooth or if it is partially erupted it can be due to Peritonitis. I will suggest you that you should consult dentist and go for investigations IOWA X-ray of tooth if it is impacted then go for extraction, if it is partially erupted peritonitis then go for Curettage. In meantime do warm saline gargle two - three times a day, for reduced mouth opening you can take muscle relaxant by consulting with your doctor. Hope it will help you. Wishing you good health.   </s>
