Is my dentist charging too much?

First off I want to say that this guy is very thorough I have never met a dentist that took the time to show me 20-30 pictures and explain and cared about my teeth. His quality is amazing. That being said I want to make sure his prices are still good. $532 to remove an old worn out crown and put in a new porcelain one. is that overpriced? my insurance pays 100% but I only have a few hundred left this year. thanks
