what is difference between plaque and tartar
Tartar, also known as calculus, is plaque that has not been properly removed and has hardened onto the surface of the tooth. Unlike plaque, tartar is visible. It is a yellow or yellowish brown deposit that encrusts the tooth along the gumline. It is much stronger than plaque and is difficult to remove; brushing and flossing will not remove tartar. Tartar must be removed by a dental professional.
Find a Periodontist. Plaque is the sticky, colorless film that constantly forms on your teeth. Bacteria live in plaque and secrete acids that cause tooth decay and irritate gum tissue. This irritation causes an inflammatory reaction by your body that can eventually lead to gingivitis and periodontal disease.
