DENTAL ENCYLOPEDIA

Educate yourself on variety of dental topics.

Dental Plaque

Dental plaque is a soft, translucent and tenaciously adherent material which consists of a gelatinous mass of bacteria accumulating on the surface of teeth. The plaque bacteria metabolize refined carbohydrates for energy and produce organic acids as a by-product. The acids produced may then cause a carious lesion by dissolution of the tooth's crystalline structure.

It is more accurately described as bacterial plaque because it is composed almost completely of bacteria and their by-products. Plaque is neither adherent food debris, as is widely and erroneously thought, nor does it result from the haphazard collection of opportunistic microorganisms.

The accumulation of plaque on teeth is a highly organized and ordered sequence of events.
