I totally agree with the consensus and it supports my personal experiences, which I wanted to share because they seem so similar. I never had a single cavity in my entire life and I decided to go to a new dentist after my family dentist retired. People recommended one dentist and I made the mistake of going to him. He did a lot of xrays and then they proceeded to tell me that my gums were at risk of receding in places. I was pressured to have a cavity filled right then so I wouldn't need a root canal. I had the filling done but I have since refused to go back for additional recommended procedures. The filling has caused me pain and I can hardly floss in the area. They filed it down but remaining issues make me wish I didn't get a filling for my first supposed cavity which I never even felt. Others have discounted my story but I am happy to stay away from unnecessary treatment that causes problems and just take care of my teeth with a strong hygiene routine.
