Healthy and white teeth can add a lot of color to the image of the whole person, but if the teeth have pigmented teeth, fluorosis, tetracycline, etc., the image will be greatly reduced, so how to treat discolored teeth? Let’s ask the experts of the dental hospital to explain to you.
Porcelain veneers can be used to treat discolored teeth. For the treatment of discolored anterior teeth, especially severe discolored teeth, the efficacy of bleaching is not very satisfactory. The use of light-cured resin veneers has poor color and luster, which is easy to cause gingivitis and easy to fall off. Porcelain veneer can be prepared very thinly, only 0.5-0.8mm thick, very little tooth tissue is removed during tooth preparation, no adjacent relationship is damaged, the gingival margin is flush, no shoulder table is prepared, and the patient suffers less and is easy to accept ,easy to use.
All-ceramic has good biocompatibility, is not easy to cause gingival reaction, and has a smooth surface, realistic and coordinated color, and clear layers. It is an ideal cosmetic restoration material for discolored teeth. However, all-ceramic veneers are not suitable for patients with teeth without sufficient bonding area and poor oral hygiene, abnormal occlusion, overocclusion and bruxism, in order to avoid treatment failure.
The bonding of all-ceramic veneers is a key step, and the process needs to be strictly moisture-proof to prevent contamination by saliva and other foreign objects. The tissue surface of the porcelain veneer and the lip surface of the tooth should be closely spaced, the adhesive should be as little as possible, and air bubbles should be prevented, otherwise it is easy to fall off. The opening and polishing of the abduction gap of each tooth lip avoids connecting the porcelain veneer into a whole piece, so that the shape and color are realistic, and the comfort of the patient is greatly improved.
Porcelain veneer has been widely used as a dental cosmetic restoration method to improve the color of anterior teeth, and porcelain veneer to repair anterior tooth gaps and tooth surface defects. The main advantages of porcelain veneers are that they have good histocompatibility, good chemical stability, good transparency, stable color of porcelain veneers, color matching of porcelain veneers, color close to natural teeth, good wear resistance, and better wear resistance. Full crown restoration of tooth tissue less grinding and so on.
