A scale and clean (sometimes known as a "polish and clean" or "scale and polish") is done to physically remove the plaque and calculus (see Gum Disease Treatment) around the teeth and gums. It is essential for good oral health that this is done on a regular basis. The average frequency for a scale and clean is every 6 months. If your gums need more care, approximately every 3 months is recommended. On some occasions, people with excellent oral health routines and very low sugar diets may be seen every 12 months (but these are remarkable and rare individuals!).
