Something like this happened to my father when he went to a new dentist after moving. Lot of fillings. Then he thought, Hey, I hadn’t had a cavity in years, where are these all coming from? and decided to see a different dentist.
I don’t know much about it, but I understand that dentists can take more or less aggressive or conservative approach. They might not all handle the same stuff the same way. One might watch a little patch of decay, while the other might say it would eventually need filling so do it now. I want the conservative approach. I’ve gone in for a crown, but then my dentist took X-rays and decided to try to fill it and was successful. He says that he uses a very small drill to take as little tooth out as possible, and has to repeatedly check to see if he’s gotten all the decay. And then once he had gotten all the decay, there was a possibility there wouldn’t be enough tooth left to hold a filling, and need a crown anyway. Fortunately, the filling worked. That saved me hundreds of dollars, but more importantly, a lot of natural tooth.
He says that his fellow dentists say he is crazy to take the time to do it this way, but he says that’s what he would want for himself or his family, so that’s what he does for his patients. (He does make up some of the time by being insanely efficient about everything. You’d think he had done time and motion studies on every procedure, and if his assistant is 2 seconds late handing him the tool he needs, she hears about it.) Needless to say, I’m very glad I found this dentist. Several different friends, who don’t know each other, all recommended him.
