Professional tooth cleaning
- and removal of discolorations with powder blasting equipment
Professional tooth cleaning (PZR) or tooth maintenance therapy (ZET) is a main component of individual dental prophylaxis. It is understood as a comprehensive mechanical cleaning of the teeth, which regularly supplements daily oral hygiene. As a rule, PZR includes complete removal of hidden soft and also mineralized plaque above (tartar) and below (calculus) the gums.
Cleaning is done with hand instruments (scalers) and ultrasonic devices. Subsequently, any remaining discolouration and deposits on tooth surfaces (also on dental crowns and dental bridges) are removed by using a powder blasting device. Comparable to sandblasting, a heated mixture of air, water and a special cleaning salt blows the plaque from every tooth surface and also from the interdental spaces. The teeth are then polished with a rotating rubber cup or a rotating small brush using increasingly fine prophylactic pastes to smooth the tooth surfaces and make it more difficult for plaque to build up again. Finally, all tooth surfaces are treated with a special fluoride varnish to protect the enamel and a disinfecting gel is applied to the gingival pockets.
