Cleaning your teeth means cleaning your teeth and mouth. The main purpose is to prevent periodontitis and tooth loosening and reduce the prevalence of dental caries. Of course, it can remove bad breath and yellow spots on teeth, depending on whether it is congenital or acquired. If it is congenital, tooth washing can't be removed. If it is acquired, the pigmentation caused by tobacco stains and tea stains can of course be removed.

Try not to pursue the form, whether it is ultrasonic or pneumatic (the advantage of pneumatic machine is long service life, but this is of little significance to patients) or manual scaling, as long as it can clean teeth.
