These provide a steady or pulsating stream of water escaping
through a nozzle under pressure. Oral irrigators should not be
used as a substitute for toothbrushing, and are time-consuming
and messy to use. There is also a risk that patients using irrigation
devices may believe them to be more effective than proved, and
reduce their efforts in manual plaque control. Nevertheless,
supragingival irrigation has a small adjunctive effect on plaque
removal and gingivitis, particularly in areas of the dentition not
readily accessed by conventional mechanical means. In special
cases, irrigation devices may have a role in the delivery of chemical
agents to the oral cavity.
