How to Soften Calculus

   If you are working with old tenacious calculus...don't try to take it off in one appointment.  It builds in layers..think of an onion. The outer layer is the softest and the innermost layer is the most tenacious.  I get as much off as I can with a sonic cleaner. Basically I do a gross debridment throughout the mouth. Then I reschedule the patient in two or more weeks.  The outer layer of calculus will soften in those two weeks.  I repeat the process...most of the time three appointments will do it...one time it took me five appointments on a lady in her fifties who had never had a cleaning.  Refer to my blog "Calculus and it's Characteristics" and "First Time I See the Patient"
