I had a similar experience after taking a many, many year break from dentists.

The first wanted to give me a root canal surgery and over 15 fillings. No thanks.

The second wanted to give me 8 filings, sell me an expensive bite guard for tooth grinding, which the first dentist did not bring up, and give me a fluoride treatment. No thanks.

The third dentist gave me 3 filings, said nothing about tooth grinding, and recommended a water flosser.

I got the three filings, bought a 'rest in peace' nightguard from amazon, started using conical hydroxyapatite toothpaste and a water flosser, and am taking another break from dentists! When I go again, I'll go to the third one. I found it impossible to figure out which is which from "reviews".
