Removal of dental calculus (or scaling, scaling) is a procedure during which tartar is removed, which is formed as a result of accumulation and calcification of dental plaque, food remains and bacteria. The resulting calculus causes, for example, the initiation of inflammation of gums and periodontium, lowering and revealing of dental cervixes, which in turn may cause bone atrophy and, consequently, gradual loosening of teeth and their fall out (parodontosis).
Scaling should be performed at least twice a year.
