To minimise the amount of heat generated, the prophy cup should not rotate faster than 1000 rpm (revolutions per minute). Plenty of prophy paste should be used to reduce friction, and a gentle pressure applied. A soft cup that can gently flare with light pressure should be used. This allows subgingival polishing. A new cup should be used for each patient to avoid cross contamination. The prophy paste should be individually dispensed from a large pot, or individual pots used to avoid contamination. A fine paste should be used to avoid superficial scratches on the surface of the tooth. A fine paste will not feel gritty when rolled between the finger tips.
