Is Filing Down the Backs of Zirconia Crowns Bad?

jchamplain92Nov 12, 2012

He polished them, but I am still afraid that some of the zirconia may have been exposed during this process. Do I have anything to worry about. I am finally confident with the way my teeth look after years of braces, bonding, crowns, and adjustments. I would hate to have more problems.
