<s>[INST] Hi, my name is , i m 32 yrs old. i had a chipped/broken front tooth since i was a little girl.inside my nose on same side where the tooth is damaged, i would have a painfull pimple that would get swollen and filled up with pus , causing sensibility in that tooth. i recently had that tooth repaired thinking the problem would ceased but it didn t. Is this some thing major(should i freak out?) what can i do to resolve this problem? Please help, any information is appreciated. Thanks [/INST] Hello there, According to your history I can suspect your broken tooth has undergone infection since the tooth was traumatized and broken tooth exposes the dentin to oral environment and food lodgment in the area leads to bacterial infection.  The infection in the tooth has gone worse due to its spread to the underlying tissues that have lead to formation of pimple like growth in the affected area or a pus pocket.  The symptoms of pain and swelling needs to be subsided by a course of antibiotic and analgesics before starting treatment.  The infected tooth can be treated by root canal procedure to devitalize it permanently and save the tooth or of the prognosis is poor the tooth can be extracted.  Get an x-ray done the affected area and approach a dentist for the treatment.  Meantime you can start with antibiotic augmenting 625 mg with analgesics two times daily, this helps in subsiding the swelling and pain.  I hope this helps, take care. </s>
