Explaining black rims around porcelain veneers
It is very unfortunate when patients need to see a cosmetic dentist for porcelain veneer remakes because of black rims around porcelain crowns and porcelain veneers. The black line or dark stain around the rim of the tooth can be caused by two main problems. One of the problems may be that something went wrong with the dental bonding or the adhesive that fixes the crown or veneer to the tooth. The second problem might be that older crowns and veneers usually were constructed with a silver or metal base that has discolored over time. Either problem is unsightly and understandably distressing for patients.
The problem with darkening around the edges of porcelain veneers is often contamination. The bonding technique can fail if the edge of the veneer becomes contaminated with blood, spit, or fluids during the bonding process. It is very difficult to bond porcelain crowns and porcelain veneers at the gum line. This is why it is important to see a trained and qualified cosmetic dentist for restorative work. Patients not only express concerns about dark lines around their existing porcelain veneers, but they are also concerned that if they redo their porcelain veneers they eventually will see the same dark, ugly line in time. The modern veneers and dental bonding agents of today are less likely to present the same problem.
Metal-based porcelain crowns
Originally, porcelain veneers and crowns were made with a silver-colored base. This metal base was used to give strength to the porcelain and to help prevent veneer fractures. Unfortunately, as the veneer edge reaches the gum line, the porcelain is much thinner, and eventually, the metal will be visible.
Cheap non-precious metals
To make matters worse, some veneers and crowns were constructed with a metal base that was framed by cheaper, non-precious metals such as tin. These metals can actually leach out and stain the gum edges. Worse yet, most people proved to be allergic to these cheap metals, making the gums inflamed and bluish in appearance at the edges.
