■ Tips You can try to use 【Tooth Powder】 Tooth powder is very effective, just get up early and brush once before going to bed. Results appear in about five to ten days. very effective. However, if your teeth are yellowish in color, you may need to go to various dentists for help.
■ These three methods are also good 1: Cold light whitening: When you take photos, you will be sore in your head, and you will continue to be sour for three days after returning home! But there is a clear whitening effect. 2: Whitening Teeth Pen: It has a brush head at the front end, brush it on each tooth before going to bed, get up the next morning and then brush it off, it also has a good whitening effect.
■ At present, the teeth whitening work that dentists can do are about the following:
●1.Ultrasonic cleaning: The cleaning paid by the health insurance is mainly aimed at removing the calculus part of the teeth. Because calculus is more likely to cause the accumulation of dental bacteria, resulting in gingivitis and periodontal disease. Therefore, the removal of dental calculus is a medical act. Of course, at the same time as the treatment, the calculus on the neck of the tooth and the adjacent surface are removed, and the teeth will also have whitening performance. Thick layers of staining can also be removed by ultrasonic scaling; however, where the teeth have cavities, grooves, or adjacent surfaces, staining is not easy to remove.
● 2. Intestinal cup plus paste polishing: This is the traditional way of teeth whitening. The paste is prophylaxis paste. It removes staining from the smooth surfaces of teeth. Restore teeth to their original color. But there is still no way to remove the staining in the pits, grooves, and adjacent surfaces.
●3. Tooth sandblasting treatment: The dental sandblasting treatment machine composed of water, air and particles, Air-powder system, can remove all stains on the tooth surface. Including cavities, grooves, and abutting surfaces on the tooth surface. The particle it uses is Sodium Bicarbonate. The above methods mainly remove the plaque, calculus, and staining attached to the tooth surface, and restore the original color of the teeth, so as to achieve the effect of cleaning and whitening. If the color of the teeth itself is changed, I am afraid that it is necessary to use peroxide drugs to achieve the effect of whitening teeth.
●4. Active tooth bleaching: Use a personal tooth whitening tray, put 10% carbonated hydrogen peroxide, and set it firmly on the teeth. The color of the teeth will gradually become lighter and whiter as the time of drug action increases. The benefit: patients do it themselves at home. Patients can decide for themselves how many teeth they want to bleach. The number of times to bleach, the time of each bleaching. And the end of the whole course of treatment, stop time. Its disadvantage is that it takes a long course of treatment, about 2 weeks, to achieve the whitening effect that the general patient wants. In addition, the drug itself is harmful to the teeth and soft tissues. It is best to do it under the guidance of a dentist.
●5. Plasma teeth whitening: It also uses peroxide agent, which is coated on the surface of the teeth, irradiated and deactivated by a plasma machine, and catalyzed by the redox reaction of the drug to achieve the effect of teeth whitening. It takes about 1 hour for each course of treatment and must be done in the dental clinic. The whole course of treatment is 3 to 5 times to achieve the whitening results desired by ordinary patients. It is usually done on the front teeth of the upper and lower rows, and on the buccal side. Counting from the center line, the upper, lower, left and right sides, 4 teeth on each side, 16 tooth-like sides.
6. Laser teeth whitening: It uses a higher concentration of bleaching agent (H2O2 hydrogen peroxide), with an appropriate laser dose, to bleach the organic pigments in the teeth from a carbon ring structure to a hydrophilic and non-pigmented structure, and To achieve safe whitening effect.
