What's that Word? Dental Jargon from A to Z: C is for Calculus & P is for Plaque, Periodontitis & G is for Gum Disease, Gingivitis

Dental plaque is a light yellow substance formed when bacteria in the mouth attach to teeth. 

Microorganisms that attach to their surface can remain in place for long periods of time. Approximately 1,000 species of bacteria can form biofilms on the teeth.  

Dental plaque can be easily removed during the early stages of its formation.  It is mineralized into tartar (also known as calculus) after approximately 10 days.  

Calculus is dark yellow hardened plaque which has hardened so it cannot be removed with a toothbrush.  It can only be removed with professional dental tools.

Plaque can contribute to tooth decay (cavity formation) and gum disease (gingivitis and periodontitis).
