The fee an insurance company pays is so low that the dentist has to cut corner to break even. Get of dentist skimp everyway possible on insurance cases. Get to know one dentist and ask him if he uses generics. Pay for the real thing.
Generic quality is usually so bad that the final result is poor. Well done dentistry will be in your mouth for years. When you amortize it out we are talking pennies. Would you believe that a major insurance company has a deal for the dentist to have crows made in CHINA. Ask who, how, where, why, when and any other question you can think of.
If you don’t get a full answer, move on. There are lots of dentists. You have every right to a full, unhurried explanation. And by the way, if you don’t see the same dentist every visit, run, don’t walk.
