I feel at this point that dentistry is closer to chiropractics and homeopathy than actual science. Many years ago I wasn't in the best financial position and went to the dentist. He identified a number cavities needing filled and quoted a hefty sum, and I put off the procedures because I couldn't afford them. I diligently saved for 6 months to pay for them and when I went in for my next checkup, I asked about them. What cavities? No your mouth looks fine. I've had similar situations with my children, getting quotes for thousands of dollars worth of work. Getting second opinions and using different insurance changes those quotes and scope of work dramatically. At this point in my life, I don't trust dentists at all. I'm sure they're not all crooks but how do tell?
