What is the difference between porcelain and metal crowns
I have to get a crown and my dental insurance states they cover for full metal and porcelain fused to metal crowns.  My dentist said he would do either and a coarse the full metal crown are more more affordable for me.
The tooth that I need a crown on is all the way in back on one of my back molars.  I am really do not care about it being metal since no one really going to see it anyway. But beyond just what they look like is there other differences that I should know of before making my choice.
