Non-surgical therapy  removes  plaque and calculus by controlling the growth of bacteria and  by treating conditions that encourage gum disease. This type of treatment may be all  that needed, especially  when periodontal disease is caught early.  Your periodontist may ask you to talk with general dentists, who may provide some forms of non-surgical therapy.  You may also need to have certain procedures, such as replacing worn fillings that can accumulate plaque, taken care of before periodontal therapy can begin.

Scaling  is a  type of  cleaning that  removes'  plaque and calculus from the teeth at and slightly below the gum line.

Root Planing smoothes the root surfaces, so the supportive tissue can better reattach to the tooth surface. Your periodontist may use local anesthesia, because this procedure goes deeper than regular cleaning.

Antibiotics
Because bacteria cause periodontal disease, you may receive antibiotics. These may be in pill form or to be applied directly to the infected area in the form of tiny fibers.  An antibacterial mouth rinse may also be prescribed to help control plaque.
