Dental scaling is the most common non-surgical technique to treat gum disease, and also known as periodontitis. The scaling procedure keeps your gums healthy and firm. Scaling is a type of dental cleaning below the gum line to remove plaque buildup. The process of scaling and root planning is often referred to the as deep cleaning of teeth. Dental scaling is done with manual instruments and ultrasonic instruments or both. Scaling is a safe and routine procedure that does not damage the tooth surface in any way.
