There is usually no harm in making your teeth whiter by scaling them. The most common scaling method used today is ultrasonic scaling, which removes calculus, plaque, tartar, and pigmentation from the teeth through ultrasonic vibrations, restoring the teeth to their original color and looking a little whiter. In addition, scaling can assist in the treatment of gingivitis, periodontitis, etc., and relieve oral odor, which is important for the maintenance of oral health. However, some patients may experience tooth sensitivity after scaling, which can generally be gradually relieved and disappeared after a short period of time. Frequent scaling or incorrect scaling can also cause some damage to the hard tissues of the teeth. Therefore, if you need to have your teeth scaled, it is recommended that you choose a regular medical institution, and you should also pay attention to brush your teeth carefully and maintain good oral hygiene in general.
