I can relate to an extent. I have yet to have any WL procedure but have had a few dental nightmares from 2015-2018. In retrospect, the thing I wish I got was second opinions. If it's possible to get a consultation with an endodontist, I think that would be a good thing. I regret letting the dentist I had before do my caps (without doing a root canal). I think it's possible an endodontist might have a better idea if a root canal is possible or not. The second dentist I got, whom I really like, when those teeth that had crowns abscessed, sent me to an micro-endodontist and he was able to save all my teeth and the existing crowns when my first dentist just wanted me to get them pulled. I do know implants need to be screwed into your jaw so that needs to be in good shape. I know it can be cheaper to let your general dentist do that kind of work, but my experience tells me sometimes specialists are best. Best of luck!
