Smoke stains on teeth can be removed by sandblasting and ultrasonic supragingival cleaning. 1. For people who smoke for a long time, a layer of smoke stains will be attached to the surface of the teeth. If you want to remove them effectively, you can go to the doctor for treatment through sandblasting, ultrasonic supragingival scaling, and tray whitening. Among them, the more widely used is ultrasonic gingival scaling, which requires no anesthesia and has no side effects. 2. Ultrasonic gingival scaling mainly utilizes high-frequency, high-energy vibration generated by ultrasonic waves to promote the crushing of dental calculus, and then through the water mist generated by the scaling machine to flush the crushed stone and plaque, in order to achieve whitening of the teeth, prevention of dental diseases, and removal of bad breath and other purposes. The operation is contraindicated for those who have pacemakers or suffer from acute leukemia, aplastic anemia, or AIDS. It is recommended to go to a regular hospital for the relevant treatment in order to achieve the ideal purpose of removing smoke stains on teeth. It is also recommended to quit smoking, drink more water and improve oral care to minimize the adhesion of tobacco stains.
