I had a similar experience with a dentist. All my previous experiences I had minimal issues, and then suddenly at a different dentist I needed several fillings and needed to drill a good tooth to "fix a cavity" in-between my teeth. I didn't get any of that done. My next visit at a different dentist a couple years later and I had a single tooth that needed a filling. When something feels off, it's always good to get a second opinion.
