  • Gum-colored dental composite and dental restoration kit
    Patent number: 5430074
    Abstract: A gum-colored dental composite is provided which may be used in class V dental restorations or as a cosmetic coating for the gingival portion of a tooth. A kit is also provided which enables a gum-colored dental composite to be formulated which closely resembles the natural gum coloration of any patient's gums. The dental composite may be used to counter the illusion of long teeth which occurs when a gum line recedes. The dental composite may also be used on other composite resins, porcelains and metals.
