I have a black eye on left side. 3 days now. I also have an abscess on end of root of upper left canine tooth. I've already had 3 rounds of antibiotic, once before my root canal and two after. At initial root canal, dentist got all the infection out, now this has developed at the very tip.The black, purple and blue puffiness under left eye is tender to the touch and I just noticed a pea-size white lump under the skin, in direct line to abcess. I know the black eye and tooth abscess are connected. My question: am I in immediate medical danger if I let this go for 3 more days?
