Dental esthetics include ultrasonic scaling, sandblasting and polishing, dental bleaching, all-porcelain veneers, and cosmetic crowns, as follows: 1. Ultrasonic scaling: also known as scaling, can remove large pieces of calculus, tobacco spots, and tea stains that cover the tooth surface, restore the original color of the teeth, and effectively relieve swelling and bleeding of the gums. 2. Sandblasting and polishing: can completely remove the exogenous pigment deposited in the sulcus of the jaw surface, and keep the surface white. 3. 3.Dental bleaching: bleaching drugs can be applied to the surface layer of yellowing teeth, combined with cold light irradiation to make the teeth white. 4.All-porcelain veneer: when the teeth are mildly crooked or have a small amount of defects, some of the enamel can be abraded to make all-porcelain veneer restoration. 5.Cosmetic crown: when the teeth are dark or poorly shaped, porcelain or all-porcelain crown restoration can be made to completely change the color of the teeth and restore the anatomical form.
