Periodontal maintenance means a procedure performed for clients who have previously been treated for periodontal disease with surgical or nonsurgical treatment. It includes the removal of supragingival and subgingival microorganisms, calculus, and deposits with hand and mechanical instrumentation, an evaluation of periodontal conditions, and a complete periodontal charting as appropriate.

Periodontitis (per-e-o-don-TIE-tis), also called gum disease, is a serious gum infection that damages the soft tissue around teeth. Without treatment, periodontitis can destroy the bone that supports your teeth. This can cause teeth to loosen or lead to tooth loss.
