Hi! I recently had a crown fall out where a root canal had been done about two years ago. My Dentist recommends an implant and refused to recemment the crown temporarily. He said the root area is too weak. I had quite a bit of work done by him about 2 yrs ago and since then, this is the third crown that has fallen out. Is this normal? I'm starting to question his work altogether. I'm not sure if he's pushing an expensive procedure unnecessarily. I'm especially turned off after reading some horrible reviews about him on the internet. What should I do? I already let him take an impression of my tooth yesterday and the ball is rolling for work to be done.
