All periodontal therapy starts with the evaluation of your oral hygiene techniques and instruction for improving them, followed by the mechanical removal of plaque and any calcified deposits (tartar or calculus) that are present on the root surfaces. This is accomplished with a cleaning technique known as scaling, root planing or debridement using hand instruments and/or ultrasonic (high frequency vibrational) instruments. Locally applied antimicrobial products or antibiotics might also be recommended during various parts of periodontal treatment to assist in healing and pocket-depth reduction, hopefully eliminating the need for periodontal surgery. Sometimes surgical procedures may be necessary to remove the deep pockets that form between inflamed gum tissue and teeth. There are many different types of surgery to handle a variety of problems. And many times, combinations of procedures are used to attempt to reduce the number of surgeries as well as the cost of treatment.
