This is a fast and safe tooth whitening technology. Low temperature luminescence avoids stimulation of the dental nerve during treatment. The main component of the whitening agent is hydrogen peroxide, which is disposable and non-irritating. The advantage is that the process is very simple, apply a protective agent on the gum margin, then apply the whitening agent on the tooth surface, use a cool white light (depend on the degree of teeth staining 8 to 10 minutes), then remove the whitening agent, and then apply a New whitening agent. This process is repeated three times, but the whole process is only 30 to 40 minutes.
Inadequate: Cold light is applied to the teeth by applying cold light to the teeth. The gel can decolorize the teeth. May damage the surface of the tooth enamel.
2, porcelain teeth
Especially in the case of dental defects, a better cosmetic repair method is porcelain teeth, which is also the best oral restoration with the best adhesion and color effect. As the surface bacteria of porcelain teeth cannot survive, besides the whitening effect, tooth decay will not occur.
Appropriate crowd: Applicable to moderate and severe tetracycline teeth, dental fluorosis, enamel hypoplasia, teeth with cracks, incomplete, pit cases of serious cases, whitening effect is obvious.
Insufficient: To make the porcelain teeth, the original teeth must be ground first, and the damage to the teeth is irreversible. The grinding of the rod-shaped teeth is very fragile. After a period of time, the gingiva, periodontitis, and gingival atrophy are complications. Possibly great.
3, veneer whitening
Veneer whitening is a layer of veneer on the surface of the teeth, which blocks the discolored teeth. Now popular tooth veneers can be divided into two kinds of resin veneers and porcelain veneers. A resin veneer is a resin that is applied to the surface of a tooth after a portion of the tooth has been rubbed off to maintain the shape of the tooth as it is. The porcelain veneer is a collection of porcelain teeth and resin veneer advantages, both beautiful and realistic, this is the latest computer ultra-precision sculpture cutting equipment and technology, will be similar to the tooth enamel "whitening patch" cut into The shape of the teeth is completely tight, and the patch is tightly embedded on the teeth with a special active interface material, so the price is relatively expensive, and the time required for holding the resin is longer.
Inadequate: Although the teeth will immediately turn white after veneering, it is very natural and realistic, but it is easy to fall off, easy to change color, easily cause gingival swelling, bleeding, inflammation and other sequelae; resin veneer has a certain thickness, will make the lips slightly convex, The appearance of the appearance of a certain degree of influence, but also expensive.
4, tooth cleaning
Tooth cleaning is the use of ultrasonic scaler and sandblast scaler to remove tartar and plaque on the surface of teeth, and to remove calculus and calcified dirt on the surface of teeth. Teeth cleaning is completely different from ordinary brushing. It can not only clean the shallow surface of the teeth, but also completely remove the plaque, stones, and pigments that can not be removed by brushing. It is easy to find small unobservable dental diseases when cleaning teeth, such as concealment. The lips and teeth achieve the purpose of early detection and early treatment.
Inadequate: just white, not whitening. After teeth cleaning, a small number of people will have teeth that are sensitive to cold and heat.
5, tooth bleaching
Bleaching is to make a transparent tray, squeeze the liquid on the tray every night and sleep on the tray. Bleaching is divided into "outside" and "inside": Outer bleaching is suitable for moderately deficient dental fluorosis and decolorization treatment of tetracycline teeth. Satisfactory results can be achieved within 3 to 5 weeks. Internal bleaching: mainly used for the repair of discolored anterior teeth, unmedicated teeth, or severe tetracycline discolored teeth. The method is to perform conventional root canal therapy, and then use a small cotton ball containing 30 hydrogen peroxide to be placed in the medullary cavity. Zinc oxide clove oil tightly sealed, 2 to 3 days dressing once, 4 to 7 times can receive better results, and finally the cavity filled with composite resin. This method is relatively large and very painful to the teeth.
Suitable population: Suitable for mild pigmentary teeth hypoplasia, due to aging enamel tooth changes caused by yellowing.
