I need your professional opinion. My very last molar, ( not wisdom) has gotten and infection. (I'm got antibiotics for it). It has gotten infected multiple times and I am on my 3rd crown. 1st was very temporary since I was pregnant at the time. 2nd was done in Michigan and was ill fitting. ( she had to redo all of the work she did on me, including three fillings, admitting she made errors when she did it. And I have since had to have all of her work redone a third time by a great dentist out here in Las Vegas) Now I am faced with a decision on what to so with that tooth. Even with the infection, there is no damage to the crown. It is not hot/cold sensitive and with the indirection clearing up it doesn't even hurt to put pressure, or chew on it. Can I just leave it be? My dentist says I need to decide quickly whether I want to get a root canal or an extraction. I have heard many bad long term effect for both. Any advice you have would be considered and greatly appreciated.
