I have a blister filled bump on my upper front gum line I have been taking antibiotics and 2 days ago the bump popped and it drained yellow puss out  and then blood my tooth is broken off in the gum line the tooth does not hurt im curious is to what is going on
Thanks for your query, I have gone through your query. The blister bump on the gums can be a pus discharging sinus tract secondary to an infected tooth or a fractured tooth. Nothing to be panic, complete the course of antibiotics particularly a combination of amoxicillin and metronidazole. Then get a radiograph done to check the amount of tooth structure remaining and surrounding bone level. If sufficient bone and tooth structure is there, then it can be restored with root canal treatment otherwise, it has to be removed. I hope my answer will help you, take care.
