Don't turn this into an anti-dentite thread!!! Dentists are your friends.
I'm a RABID anti-dentite!
When someone gives me a satisfactory explanation as to why a tiny bit of porcelain costs as much as a porcelain commode, then I'll perhaps change my opinions.
My nature is to distrust any industry where those who recommend a certain amount of service are the same as those who profit from such service.
