1. Gingival calculus: that is, the gums above the edge of the crown surface of the calculus, located in a more superficial place, through the professional ultrasonic scaling instrument for rinsing, can be very good to remove, generally recommended half a year or a year cleaning.
2. Subgingival calculus: distributed in the gums below the edge of the calculus, with the naked eye is difficult to find, cleaning is relatively more difficult, the need for a professional doctor with the help of instruments for manual subgingival scraping or the use of periodontal therapy for treatment, before the effective removal of dental calculus.
The calculus needs to be combined with the specific location, under the guidance of the doctor to choose a reasonable way of treatment, to reduce the damage to the teeth and gums.
