A "cleaning" is not a single procedure. There are actually several distinct types of dental cleanings, and the right one for you depends on the health of your gums today and any history of gum disease in your past. Two of the most often confused are routine prophylaxis (the standard six-month cleaning most adults grew up with) and periodontal maintenance (the cleaning recommended every three to four months for patients who have been treated for periodontal disease).
The difference is more than scheduling. The procedures themselves are different, the goals are different, and the long-term implications for your gum and bone health are very different.
Side-by-Side Comparison
| Factor | Routine Prophy (Cleaning) | Periodontal Maintenance |
|---|---|---|
| Who it's for | Patients with healthy gums and no history of periodontal disease | Patients who have been treated for gum disease (e.g., scaling and root planing) |
| Goal | Prevent gum disease from developing | Keep treated gum disease from progressing |
| Where the work happens | Mostly above the gumline (supragingival) | Above and below the gumline (sub- and supragingival) |
| Typical frequency | Every 6 months | Every 3–4 months |
| Appointment length | 45–60 minutes | 60–90 minutes |
| Pocket charting | Periodic | Every visit |
| Insurance billing | Preventive (D1110) | Periodontal (D4910) |
What Happens at a Routine Cleaning
A routine cleaning, technically called prophylaxis, is the gold standard of preventive care for patients with healthy gums. The hygienist removes plaque and the hardened form of plaque called calculus or tartar from the surfaces of your teeth above the gumline. They polish your teeth, often apply fluoride, and review your home care.
The visit is largely preventive — its job is to keep healthy gums healthy. Pocket measurements happen periodically (typically once a year) to confirm that gum health has not slipped. For more on what a routine cleaning involves, see our cleaning walk-through and the cleanings service page.
What Happens at a Periodontal Maintenance Visit
Periodontal maintenance is recommended after a patient has been diagnosed with and treated for periodontal disease — typically with scaling and root planing (SRP). It addresses the fact that even after successful treatment, the bacteria responsible for gum disease are still in the mouth and they regrow within a few months below the gumline.
Periodontal maintenance includes:
- Pocket measurements at every visit to track depths and identify any areas that have worsened
- Subgingival scaling — careful instrumentation below the gumline to remove bacterial biofilm before it becomes an issue
- Supragingival scaling — removing tartar above the gumline as in a routine cleaning
- Root surface review at sites of previous treatment
- Polishing and home care reinforcement
- Bleeding-on-probing assessment at every site to flag emerging inflammation
The visit usually runs 60 to 90 minutes and is scheduled every three to four months — the window in which problematic bacteria reestablish themselves and begin causing damage.
Periodontal maintenance is closer to managing a chronic condition than to preventing one. The goal is stability, and stability requires more frequent attention than prevention does.
Why Three to Four Months, Not Six?
Bacterial colonies in periodontal pockets repopulate within roughly twelve weeks after treatment, even with good home care. That is why the American Academy of Periodontology and most periodontists recommend a three- to four-month maintenance interval. Stretching to six months gives the bacteria long enough to re-establish patterns that caused the original disease.
Some patients with very mild prior disease or unusually good home care can be safely extended to a four-month rhythm; others with severe past disease, smoking history, or systemic risk factors do best at three months. Your dentist or periodontist tailors the schedule to your situation.
Different Procedure, Different Billing
Periodontal maintenance and routine prophylaxis are different procedure codes, which is why insurance often covers them differently. Most plans recognize the procedure once it has been initiated by treatment for gum disease, and many cover three or four maintenance visits per year as opposed to two routine cleanings.
Coverage details vary plan by plan. Our insurance information page explains how we verify benefits, and our in-house membership plans offer alternatives for patients without traditional dental insurance — including a periodontal-specific plan that bundles three maintenance visits per year.
What If You Have Never Been Diagnosed With Gum Disease?
If your gums are healthy — pockets at 1 to 3 millimeters, no bleeding on probing, no bone loss visible on X-rays — routine prophylaxis every six months is the right schedule. Maintaining that healthy baseline is the goal, and our resource on signs you may need periodontal care walks through the early indicators that something has changed.
If you are not sure where you stand, a comprehensive periodontal evaluation is the right next step. Your hygienist measures pocket depths at six points around every tooth, checks for bleeding, looks at X-rays, and gives you a clear picture of where your gum health is today.
Caring for Your Gums Between Visits
Periodontal maintenance is a partnership. The dentist and hygienist do their part every three to four months; you do your part every day. For details on what that home routine looks like after periodontal treatment, see our post-treatment care guide.
The Long View
Patients who commit to a three- to four-month maintenance schedule overwhelmingly keep their teeth and avoid further bone loss. Patients who skip visits or revert to six-month cleanings often see disease return. The American Academy of Periodontology's patient site has additional reading on long-term gum health.

Frequently Asked Questions
Why does my dentist say I need a "different" type of cleaning now?
Once a patient has been treated for gum disease — typically with scaling and root planing — the standard six-month preventive cleaning is no longer enough to keep things stable. Periodontal maintenance is a more thorough cleaning performed every three to four months to address bacterial buildup below the gumline before it can cause further damage. The schedule and the procedure are both intentionally different from a routine prophy.
Is periodontal maintenance more expensive than a regular cleaning?
Yes, generally. The procedure code is different, the appointment is longer, and the work is more involved. Most dental insurance plans recognize the distinction and cover periodontal maintenance under a separate benefit category, often at a higher per-visit reimbursement than routine prophylaxis. Coverage frequency varies — some plans cover four maintenance visits per year, others cover two.
Will I always need periodontal maintenance, or can I go back to regular cleanings?
For most patients, once you have been treated for periodontal disease, periodontal maintenance becomes the long-term standard. Gum disease is a chronic condition like high blood pressure — well-managed but not cured. The good news is that consistent maintenance keeps it from progressing, and most patients live their entire lives without further bone loss.
How long does a periodontal maintenance visit take?
A typical periodontal maintenance appointment runs 60 to 90 minutes — longer than a routine cleaning because it includes thorough scaling above and below the gumline, more detailed pocket measurements, and extra time to assess the health of any healed surgical sites. Patients with extensive previous treatment are sometimes scheduled for slightly longer visits.
What happens if I skip a periodontal maintenance visit?
Bacteria below the gumline regrow within a few months of treatment. Skipping maintenance lets that bacterial colony reestablish, which is exactly the condition that caused the original gum disease. Long gaps between maintenance visits is the single most common reason previously stable patients return with new bone loss. Even one missed visit is worth rescheduling promptly.
