Three years ago, I had a root canal done on tooth number 16. After a year, the dentist saw an infection on the root of the tooth and he performed another root canal. After a couple of days, the tooth is still very inflamed and sore. The dentist saw in the X-ray that there is still a small infection. The dentist referred me to a specialist to get an apicoectomy.
Has anyone had one and did it work? I do not know much about the procedure. Please help.
