What are porcelain veneers? Porcelain veneers are a type of porcelain restoration that covers part of the tooth surface. That is, the use of bonding technology, in the case of preservation of the living pulp, less grinding teeth, the surface of the tooth surface defects, stained teeth, discolored teeth and malformed teeth with porcelain restorative material bonded to cover its surface, in order to restore the normal shape of the tooth and improve its color. Porcelain veneers refer to what is considered to be the better cosmetic dental restoration method. Compared to all-porcelain crowns, veneers have many advantages. The biggest advantage is that less tooth tissue is removed. Generally only a thin layer of tooth tissue (about 0.3 to 0.8mm thick) on the labial side is removed, which is conducive to the protection of the dental pulp. The treatment is almost painless for the patient. Through color, shape, surface sculpture, internal and external coloring, and with special bonding agents, veneers can achieve almost perfect restorative effects. Indications and contraindications: 1. Indications: Various cases requiring cosmetic dental restoration, such as enamel hypoplasia, fluorosis, tetracycline teeth, discolored teeth, excessive gaps, adjacent surface caries, conical teeth, and other various cases of intact but abnormal color. In addition, a small amount of crown loss caused by trauma is also suitable for porcelain veneers. Porcelain veneers are generally only used for the restoration of anterior teeth. 2, contraindications: severe labial misalignment of maxillary teeth, severe labial tilt and displacement of anterior teeth, antimandibular teeth, deep coverage of too small anterior teeth with severe lip wear without gaps, heavy night grinding teeth, extensive composite resin restoration of anterior teeth, highly carious. Do porcelain veneers fall off easily? The porcelain veneers are not easy to fall off if the indications are chosen appropriately, the design is reasonable, the production is excellent, the excellent bonding agent is chosen, and the correct bonding method is used. What do I need to pay attention to when I have a porcelain veneer? Because the porcelain veneers rely entirely on adhesive retention, so avoid eating hard objects with veneered teeth, so as not to cause the veneers to break or fall off.
