I had a crown implanted following a root canal treatment by Dr.Wong himself in 2009. Now the bed of the Molar tooth is growing abscess or collection of fluid from time to time. This causes toothaches. And given a course of antibiotics. It soon clears up. Now the dentist is advising me to have the molar tooth removed, have the bed completely cleaned out and "a new crown put in". I am currently out of the country
Is this something I should have it done or alternatively have the molar tooth extracted altogether.
