Supragingival plaque, control

A number of devices aid in the removal of plaque from surfaces between teeth, around bridgework, and in other areas that are difficult to reach. The limitation of many of these devices is that they are effective for control of supragingival plaque but, at best, can remove subgingival plaque only to a depth of few millimeters. Therefore, they are of minimal value against subgingival plaque located deeper within the gingival crevice, as is the case in periodontal disease.

At present chlorhexidine is the agent of choice in the short-term control of supragingival plaque although it is not without its disadvantages. It adsorbs to a pellicle-covered enamel and to the surface of calculus and subsequently reacts with dietary components to produce a persistent brown stain. In addition, some patients report a burning sensation and loss of taste after prolonged use. 

Good control of plaque is accomplished by mechanical procedures, which include brushing, flossing, and professional prophylaxis. A professional cleaning is recommended at least twice a year to remove plaque and tartar (calculus), both supragingivally and sub-gingivally.
