Scaling and root planing is a careful cleaning of the root surfaces to remove plaque and calculus [tartar] from deep periodontal pockets and to smooth the tooth root to remove bacterial toxins. Scaling and root planing is sometimes followed by adjunctive therapy such as local delivery antimicrobials, systemic antibiotics, and host modulation, as needed on a case-by-case basis.
Most periodontists would agree that after scaling and root planing, many patients do not require any further active treatment. However, the majority of patients will require ongoing maintenance therapy to sustain health.
