I believe it. Been suspicious since wisdom teeth removal. Was told I'd better remove them as they were growing at an angle. Forgot about it, teeth grew in fine, never looked back.
The other thing that really makes no sense is the cost of visits vs premiums charged. Dental tends to be a pretty small premium, and last time I checked 2 routine cleanings a year, if paid in cash would cost far more than premium collected from individual across 12 months. Implies most people aren't going, and yet everything's fine. I should probably verify this last claim, but I'm pretty sure
