Scaling is usually taken clinically at present by ultrasonic scaling, and the general hospital price is around 200 yuan. After scaling, if there are more smoke spots and pigmentation on the surface that are not completely removed, you can apply sandblasting to remove them, and the cost of sandblasting is also around 200 RMB. For calculus deep in the roots of the teeth, a manual instrumentation method of scaling can be applied, called periodontal subgingival scraping, and the cost of subgingival scraping is about$20 per tooth. Generally, during periodontal systemic treatment, for deeper periodontal pockets, there will be more calculus at the bottom of the pockets, and this can be treated by subgingival scraping. It is generally recommended to clean your teeth every six months to a year to maintain oral hygiene.
