When plaque is allowed to remain on the teeth for too long, it collects close to the gums and turns into a hard substance called tartar (or calculus, which is old plaque).

Plaque is a gummy mass of microorganisms that grow on the crowns and spreads along the roots of teeth and is both colorless and transparent. Dental plaques are the forerunners of dental caries and periodontal disease. Tartar is hardened plaque deposited upon the teeth. Gingivitis is inflammation of the gums characterized by redness, swelling and tendency to bleed. See similar questions...

Tartar is plaque that has hardened on your teeth. Tartar can also form at and underneath the gum line and can irritate gum tissues. Tartar gives plaque more surface area on which to grow and a much stickier surface to adhere, which can lead to more serious conditions, such as cavities and gum disease. See similar questions...

Calculus is dental plaque that has mineralized. Calculus can form when plaque is not removed from the tooth surfaces. This plaque becomes old and eventually forms into calculus. Calculus can form above or below the gumline. The bacteria that sticks to calculus can cause gum disease (gingivitis) or periodontal disease. Calculus cannot be removed by brushing and flossing. A dental hygienist checks for calculus formation when you visit the dental office. See similar questions...
