It is very unfortunate when there are black rims around porcelain crowns and porcelain veneers. This should NOT happen! The black stain around the rim of the crown or porcelain veneers is contamination. The bonding technique was a failure as there was something that was not completed thoroughly.

Oh no, my childâs front tooth is turning dark! What is going on? A child may have a primary baby tooth turn dark if he or she bumps and injures it. Usually this happens a few weeks after an accident. It will usually turn a gray or purple hue. In general, if the tooth is displaced or knocked very loose at the time of the injury, there seems to be a greater chance of it turning dark. If it doesnât turn dark after a month, it likely will be on a road to healing.
