Root planning is a specialized skill involving scaling of the root of the tooth, made up of cementum. A smooth cementum provides less opportunity for bacteria to hang out and form calculus, so root planning is an important part of stopping periodontal disease where it is at, and preventing periodontal disease from getting worse, especially once deeper pockets have formed in the gums, which is really in the bone. So, root planning is a specific treatment that removes the roughened cementum and surface dentin that is impregnated with calculus, microorganisms and their toxins."
