PZR stands for “Professionelle Zahnreinigung,” which is German for professional dental cleaning. It is a preventive dental treatment that involves the thorough cleaning of teeth, gums, and mouth by a dental professional. PZR includes the removal of plaque, tartar, and stains from the teeth, as well as polishing to give the teeth a smooth and shiny surface. The dental professional may also provide personalized oral hygiene instructions and advice on maintaining good oral health. PZR is important for maintaining good oral health and preventing dental problems such as cavities, gum disease, and bad breath.
