According to relevant statistics, the purpose of people to dental visits, aesthetic reasons account for more than 50%, but there are many people think that dental cosmetic only the restoration of porcelain crowns, in fact, this is a misconception, porcelain crown teeth is only a branch of dental cosmetic. Cosmetic dental restoration is a comprehensive discipline, common: teeth whitening, resin veneers or porcelain veneers cosmetic restoration, porcelain full crown cosmetic restoration, orthodontic orthodontics, and periodontal cosmetic surgery these types. Cosmetic dentistry is mainly considered from the four aspects of tooth color, tooth texture, tooth form and tooth shape, and tooth alignment, and the treatment method also differs according to the patient’s teeth in these four aspects. If the affected teeth are well aligned, have smooth enamel texture and complete morphology, and only have defects in color, such as foreign staining of the teeth caused by drinking tartar, coffee or smoking, moderate to mild tetracycline teeth, and moderate to mild enamel plaque teeth caused by long-term consumption or drinking too high concentrations of fluoride, as well as age-related changes in the teeth, cosmetic tooth bleaching can be used, which is appropriate and does not cause any damage to the teeth. In addition to the color change, the affected teeth are accompanied by small morphological defects and defects in the texture of the enamel, which can be considered for cosmetic restoration with resin veneers or porcelain veneers with minimal damage to the dentition. If the defect is more severe and involves the pulp to form a dead pulp tooth, a porcelain full-crown cosmetic restoration can be chosen, including cast porcelain crowns, aluminum oxide crowns, and zirconia porcelain crowns. Patients with only misaligned teeth may be considered for orthodontic treatment. Older patients who are not suitable for orthodontic treatment or those who have most of the tooth tissue missing and only the roots remain should not consider tooth extraction and can undergo porcelain pile crown cosmetic restoration. Those with poor gum morphology may consider periodontal cosmetic surgery.
