ROOT PLANING AND SCALING (DEEP CLEANING) - A "deep cleaning" is the procedure typically performed by a dental hygienist to remove hardened deposits of plaque below the gum line of the teeth. The teeth and gums in the area of treatment are anesthetized so the procedure can be completed comfortably and thoroughly. Removing the plaque deposits allows the swollen and bleeding gums in the area to heal. Medicated antibacterial rinses are usually used at home after treatment to aid the healing process.
