Calculus or tartar is hardened dental plaque. It is caused by the continual accumulation of minerals from saliva on plaque on the teeth. Its rough surface provides an ideal place for further plaque formation, threatening the health of the gum tissue.
Brushing and flossing can remove plaque; however, once calculus forms, it is too hard and firmly attached to be removed with a toothbrush. Calculus buildup can be professionally removed with ultrasonic tools and specialized dental hygiene instruments during your regular dental visits.
