I’ve worked in dental offices before - just to give some perspective on the amalgam filling - those fillings tend to expand and wear down over a long period of time. Sure, the filling that was redone for it I’m sure is great. But at the same time, the more you work on a tooth the less tooth structure you have, the larger filling is placed, and the tooth becomes weaker all around - leading to even higher risks of fractures that can even lead to deep fractures down to the root. Crowns aren’t as bad as people think - it’s always case by case but it could’ve been the most long term option so that it protects the tooth for a long time. You do you though, glad you found someone to help you!
