Teeth cleaning paid by health insurance is mainly aimed at removing dental calculus. Because dental calculus is more likely to cause the accumulation of dental bacteria, causing gingivitis and periodontal disease. Therefore, removing dental calculus is a medical behavior. Of course, at the same time of treatment, the calculus on the neck and adjacent surface of the tooth will be removed, and the teeth will also have whitening performance.
For thick stains, most of them can also be removed by ultrasonic cleaning; however, stains are not easy to remove where there are pits, grooves, or adjacent surfaces of the teeth.
2. Bowel cup plus paste grinding:
This is the traditional way of teeth whitening. The paste is prophylaxis paste. It removes stains on the smooth surfaces of teeth. Restore teeth to their original color. But for the stains in the pits, grooves, and adjacent surfaces, it still has no way to remove them.
3. Teeth blasting treatment:
Composed of water, air, and particles, the dental sandblasting machine, Air-powder system, can remove all stains on the tooth surface. Including cavities, grooves, and abutments on the tooth surface. The granules it uses are Sodium Bicarbonate.
The above methods are mainly to remove plaque, calculus, and stains attached to the surface of the teeth, and restore the original color of the teeth to achieve the effect of cleaning and whitening. If it is the change of the color of the tooth itself, I am afraid that it is necessary to use peroxide gas drugs to achieve the effect of whitening teeth.
4. Active tooth bleaching:
Take a personal teeth whitening tray, put in 10% carbonated hydrogen peroxide, and fit it firmly over your teeth. As the drug action time increases, the color of the teeth will gradually become lighter and whiter. Its advantage is that patients can do it at home by themselves. Patients can decide the number of teeth to be bleached at their own discretion. The number of times to be bleached, and the time of each bleaching. And the end of the whole course of treatment, stop time. Its disadvantage is that the course of treatment is longer, and it takes about 2 weeks to achieve the whitening effect that most patients want. In addition, the drug itself is more or less harmful to teeth and soft tissues. It is better to do it under the guidance of a dentist.
