From a health point of view, ultrasonic cleaning is better than sandblasting, but the specific use of which method needs to be determined in conjunction with the individual’s dental condition and treatment expectations. 1. Ultrasonic scaling is the application of ultrasonic vibration frequency to make calculus and tobacco stains, plaque and other foreign matter attached to the surface of the teeth loose and fall off, so as to achieve the maintenance of dental health, as well as to remove the role of stains; and sandblasting is the use of high-pressure gun will be coarse salts such as silica sprayed onto the surface of the teeth to clean up the surface of the teeth of the teeth of the stains and pigmentation, and thus to achieve the effect of stains. 2. For patients suffering from gingivitis or periodontitis, it is recommended to use ultrasonic scaling, while sandblasting can be chosen to deal with stains and hyperpigmentation on the teeth, but this way cannot clean up the large pieces of dental calculus, between the teeth and the gums below the dental calculus. Therefore, it is recommended to go to the stomatology department of the hospital to find a doctor to determine whether ultrasonic or sandblasting is better and more suitable for you in conjunction with the condition of your mouth.
