Melissa O. SAYS!
Calculus or tartar is a form of hardened dental plaque. It is filled with millions of bacteria. Brushing and flossing can remove plaque from which calculus is formed, but once the plaque hardens to the tooth or root surface, it is too hard and firmly attached to be removed with a toothbrush. Calculus can ONLY be professionally removed by a dental professional.
