Black Line Removal

 

On many occasions, new patients come to us with concerns about dark lines around the edge of their existing porcelain crowns or where their veneers meet the gumline. This should really never happen if the proper procedures and high quality materials are used.

There are two reasons why these dark lines appear:

1) The use of Porcelain materials containing metal

Traditionally, porcelain crowns have a silver-coloured metal base, and some use an even less expensive non-precious metal base such as tin. As the porcelain reached the gumline, it gets thinner and thinner and eventually the metal base will show through. This becomes more prevelent as the gum recedes over time and after years of use. These metals can eventually leach out and inflame the gums turning them bluish in appearance along the edges.

2) Porcelain crowns that don't fit well

If the porcelain crowns are not fitted properly or sealed well, there is the likelyhood of accumulation of staining at the tooth's edges. This not only creates the dark lines, but it can actually damage the underlying tooth by trapping bacteria and plaque and starting the process of tooth decay.

At Vitality Dentistry, we use materials and procedures that never allow these situations to develop. We use only the best porcelain available - never metal based materials. As well, the porcelain is bonded to the teeth, rather than cemented, to give the porcelain strength and also to avoid the possibility of fractures. We take extra precautions to make sure the porcelain crowns and veneers create a glass like finish against the tooth that minimizes staining at the edges of the tooth and doesn't allow any leakage underneath the tooth.
