This procedure involves smoothening the root surfaces of your teeth so as to remove the tartar that is accumalated below the gum level. The gum tissue can more firmly rettach to the roots that are clean & smooth to prevent tooth loss & sensitivity problems. Because this procedure goes deeper than a regular cleaning your mouth may be numbed or anesthetised by a local anesthetic. The cleaning may take two or three visits to complete. It is done in cases with mild periodontitis to prevent further deterioration.
