Periodontal therapy, also known as periodontal treatment, is a set of procedures aimed at treating gum disease (periodontal disease) and restoring the health of the gums and supporting structures of the teeth. It encompasses both non-surgical and surgical techniques, depending on the severity and progression of the disease. Periodontal therapy is crucial for preserving the health and function of the teeth and supporting structures and for preventing tooth loss associated with advanced gum disease. Early intervention and proper management are key to successful treatment outcomes.
