Calculus (Dental)

In dentistry, calculus is a form of hardened Dental plaque and is synonymous with tartar. It is caused by the continual accumulation of minerals from saliva on plaque on the teeth. Its rough surface provides an ideal medium for further plaque formation, threatening the health of the gingiva. Brushing and flossing can remove plaque from which calculus forms; however, once formed, it is too hard and firmly attached to be removed with a toothbrush. Routine dental visits are necessary so that calculus buildup can be professionally removed with ultrasonic tools and specialized sharp instruments.
