  1. After deep cleaning or gum surgery, this closer cleaning becomes part of the routine
  2. At each visit, the hygienist cleans below the gum line again, the same way as before
  3. Between visits, plaque quietly builds back up along the gum line
  4. That's why these visits repeat every three to four months, sooner than a routine cleaning
  5. Each visit clears it back out, which is what keeps it from building up again

Who usually does it

hygienist. Done in the general office or by a periodontist, alternating between the two in many cases.

Gum maintenance cleaning

Cleanings and gum careBasicD4910

D4910. The follow-up cleaning after gum treatment; plans count it against your cleaning allowance and some pay it as basic rather than preventive.

After a deep cleaning or gum surgery, this is the ongoing cleaning that keeps gum disease from coming back. It goes deeper than a routine cleaning and is usually scheduled every three or four months.

This is the cleaning that follows deep cleaning or gum surgery, and it goes further under the gum than a routine cleaning does. Offices usually schedule it every three or four months rather than twice a year, because that is the window in which the bacteria build back up in a pocket. Some plans count it against the routine cleaning allowance rather than adding to it. Most plans file this as Basic. What they actually pay varies by plan.
