Why do some crowns reflect a black line between them and the gums?
This is caused by the underlying metal lining of the crown which makes the tooth look artificial and fake. Contemporary cosmetic dentistry affords us to completely avoid this unsightly problem. When it is absolutely unavoidable to use crowns we prefer to use all porcelain crowns. The strength of this crown is similar to the metal lined porcelain crowns and some even suppress surpass that. All porcelain crowns allow light to pass through just like the enamel on teeth does. When the porcelain is artistically layered to fabricate a crown it will look natural and no one can tell a cap was placed over the tooth. When the tooth is prepared properly and the correct ceramic is used for the all porcelain crown, teeth will not only look real, they can actually look better than the original shape and color.
