Periodontal Maintenance, or Periodontal Cleanings, are continued periodontal therapy. Periodontal (Gum) Disease is a chronic problem, much like diabetes, and must be controlled through regular periodontal cleanings (even though you may have had periodontal surgery or non-surgical treatment). The schedule will vary from case to case, but typically periodontal cleanings are required on a more frequent basis than the six month interval often recommended for patients with healthy gums. The interval between cleanings that's right for you will be determined by Dr. Herman following your initial periodontal treatments.
