I had a root canal done on my front tooth about 5 years ago. It has an enamel cap on it. It has 3 puss pockets over it and hurts. What could be wrong with it? I am 73 years old, 6 3 tall. I am currently taking an antibiotic. Bill
Hi, It looks like the root canal treated tooth is infected. A pretreatment of the tooth is required which will help in resolving the infection.  Antibiotic will temporarily remove the infection, but it will reappear if the treatment is not done
