Yo, I'm an actual mountain biking dentist. For real! The dudes tooth is likely
blue from either having a little bit of nerve tissue left over after the root
canal, or from having the root filling too high in the tooth (there's a dark
rubbery bit for the root, and a second nice white bit for the coronal area).
He should try seeing a dentist for internal bleaching before opting for a
crown!
