Deep cleaning is also known as scaling and root planing, conventional periodontal therapy, or non-surgical periodontal therapy.

Bacteria plaque is the main cause for gingival inflammation and progression of periodontal disease. Thus the initial step for treatment of periodontal disease is to remove any factors that help retain plaque around teeth such as tartar, calculus and overhang restorations.

To ensure patient comfort, local anesthetic is sometimes administered in selected areas.

Deep cleaning is also part of preventative and maintenance stage of periodontal therapy.
