Have you ever seen someone smile and then you notice a black line right at the gum line of the person you’re talking to and wondered what it was? Well, that black line is the margin of a crown that has metal under the tooth-colored porcelain. Dentistry has come a long way and today if a patient needs to correct a broken or chipped tooth they don’t have to suffer the embarrassment of having the metal show from under their crown. A metal free crown is one that is made entirely of porcelain and can be custom matched to your existing teeth without any margins showing. Although an all ceramic crown/bridge may not be right in every situation, in most cases we can use this new type of full coverage crown to restore teeth.
