$93k dental work sounds like an outlier. In a free market, $93k dental work should be as rare Bentley's on the road. There are very few people who can afford $93k procedures, so dentists/doctors will have to figure out how to do the procedure for a lot less or deal with the fact that their target market will be extremely small.
Besides, isn't the entire purpose of insurance to smooth out the outliers? $500k cancer treatment is an outlier, too, which is why I have medical insurance that covers it.
