1. I used to work for a chain dental clinic (won’t list which one), and it was the worst 6 months of my life. Now, not ALL dental chains are like this, but from my experience, most are.
Every patient who walked in the door (with insurance) had gum disease and were charged with a ‘deep cleaning’, even when they only needed a regular prophy ($90 whole mouth cleaning compared to $180/quadrant). Any amalgams in the mouth were to be removed and replaced, regardless of if there was any decay underneath. Any filling 2 surfaces or more (which is many fillings) indicated a crown, again, even if completely sound.
