Tooth Decay or Metal Oxidation?
When a patient has black lines around the crowns it appears like tooth decay and it actually may be tooth decay. However, it can also be a metal oxidation process on porcelain fused to old-style metal crowns or it can be a stain in the space between the crown and the tooth as with porcelain crowns and porcelain veneers.
The space gets stained and the dark gum line appears decayed. The best way to solve the dreaded black line around dental crowns at the gum line is to replace the crown. But, sometimes the actual tooth structure has become stained black and the black color needs to be hidden. The problem is when the dentist tries to hide the black or dark tooth color with a porcelain crown, the porcelain crown can look too opaque or artificial.
Dr. Sam Muslin of Santa Monica California was awarded LA’s Best Cosmetic Dentist for 2012 because of the quality of his work and the validity of his before and after photos of porcelain veneers, full mouth reconstructions, porcelain crowns and his unique and exclusive Face Lift Dentistry treatment.
He has developed a method of hiding the dark stained tooth color and/or removing the dark tooth color so he can make his porcelain crowns translucent and have a natural appearance. Additionally, once there is a black line around the crown at the gum line, the gums generally recede away from the dental crown because the fit of the crown is less than perfect.
Dr. Muslin says, “Porcelain crowns require perfect fits and biologically compatible materials along with ideal shapes and the gums will generally grow back to fill in the spaces between the teeth”. When the gums grow back, there is no place for the food to trap. Gums and teeth should ideally work together in order to avoid food traps and food impaction.
