If your cleanings every six months have turned into visits every three months, you may wonder what changed. Periodontal maintenance is a specialized cleaning for people treated for gum disease. It's billed under a different code (D4910) than a regular cleaning (D1110), so your appointment and your bill can both change.
The short answer: a regular cleaning, or dental prophylaxis, protects healthy gums. Periodontal maintenance controls gum disease that has already damaged the tissue and bone around your teeth. It goes deeper below the gumline, tracks your pocket depths, and usually happens every three to four months instead of every six.
At Smile Design Modern Dentistry in Durham, periodontal maintenance is part of the gum care Dr. Erfan Imeni and our hygienists provide. Here's what changes, and why.
What Is Periodontal Maintenance?
Periodontal maintenance is ongoing care for gums that have had periodontitis, the stage of gum disease that damages the bone and tissue holding your teeth in place. It begins after active treatment, such as scaling and root planing, and continues at intervals your dentist sets.
The American Dental Association's code description says this care continues for the life of your teeth, or of any implants that replace them. That's because periodontal disease can be controlled, but it isn't cured. The American Academy of Periodontology notes that most patients need ongoing maintenance therapy after a deep cleaning.
At our office, these visits include a thorough cleaning above and below the gumline to remove plaque, tartar, and bacteria. Your hygienist cleans the root surfaces inside the pockets, measures and records pocket depths, and checks for bleeding points and recession, so any change is caught early.
What Is the D4910 Dental Code?
D4910 is the code offices use to report periodontal maintenance on an insurance claim. It comes from the ADA's Code on Dental Procedures and Nomenclature (CDT), the standard list of dental procedure codes. Its description covers removing plaque and tartar above and below the gumline, scaling and root planing at specific sites where needed, and polishing the teeth.
The description adds that new or returning disease calls for more diagnosis and treatment. So a D4910 visit is a checkup on your gum disease as much as a periodontal cleaning.
What Is Dental Prophylaxis (a Regular Cleaning)?
Prophylaxis is a medical word for prevention. In dentistry, a prophylaxis, or prophy, is the routine cleaning most people know. For adults, it's reported as D1110, which the ADA describes as primarily a preventive procedure that removes plaque, tartar, and stains.
A prophylaxis is designed for healthy gums. Its job is to keep problems from starting, not to treat an infection that has already reached the bone.
During a regular dental cleaning and exam at Smile Design, our hygienists remove plaque and tartar, floss and polish your teeth, and apply fluoride if needed. Dr. Imeni then examines your teeth, gums, and mouth, using digital X-rays to find hidden problems.
We recommend these regular visits every six months.
Periodontal Maintenance vs a Regular Cleaning: What's Different?
The tools look similar, but the reason for the visit is not. Here's how the two compare:
| Regular cleaning (D1110) | Periodontal maintenance (D4910) | |
|---|---|---|
| Who it's for | Healthy gums, no history of periodontitis | Gums treated for periodontitis |
| Main goal | Prevent gum disease | Keep treated gum disease under control |
| Where it cleans | Teeth, above and just below the gumline | Teeth plus root surfaces inside deeper pockets |
| Pocket depths | Checked at routine exams | Measured and recorded every visit |
| Typical schedule | Usually every 6 months | Often every 3 to 4 months |
| Insurance | Usually a preventive benefit | Varies by plan |
| Average fee without insurance* | About $85 to $160 | About $140 to $220 |
*Average costs without dental benefits, as published by Delta Dental. These are not Smile Design's fees.
The key difference is depth. Around healthy teeth, the gum pocket is usually about 1 to 3 millimeters deep. After periodontitis, pockets can be deeper and the bone around the roots lower, so cleaning has to reach farther down the root.
Where Does Scaling and Root Planing Fit In?
Scaling and root planing, often called SRP or a deep dental cleaning, is the active treatment that usually comes first. You may also see it written as periodontal scaling and root planing, root planing and scaling, or root scaling and planing. They all describe the same procedure.
What Is Scaling and Root Planing?
According to the ADA's MouthHealthy site, scaling removes plaque and tartar above and below the gumline, down to the bottom of each pocket. Root planing then smooths the tooth roots so the gums can reattach. It may require a local anesthetic and more than one visit.
SRP is reported by quarter of the mouth, called a quadrant. Code D4341 is used when four or more teeth in a quadrant need it, and D4342 when one to three teeth do. That's why a dental deep cleaning is usually priced per quadrant.
At Smile Design, Dr. Imeni measures your pockets and takes X-rays before recommending any gum treatment. For infected pockets, ARESTIN, an antibiotic placed directly into the pocket, is typically used together with scaling and root planing.
Scaling and Root Planing Before and After: What Changes?
Right after a deep cleaning, MouthHealthy says some soreness for a day or two and tooth sensitivity for up to a week are normal. Cleveland Clinic adds that some teeth may feel slightly loose or sensitive for a while as the gums heal.
The real before and after is measured, not seen. Your dentist checks healing and re-measures your pockets at a follow-up visit. If they've improved, you move into maintenance, and if they stay deep, more treatment may be recommended.
For moderate to advanced gum disease, Smile Design also offers LANAP laser gum treatment with the PerioLase MVP-7 laser. Like SRP, it needs regular follow-up care afterward, because periodontal disease is a chronic condition. Our post on the LANAP procedure explains how it works.
Why Did Your Appointment Change?
Three things usually change when you move from regular cleanings to periodontal maintenance:
- How often you come in. Most patients are seen every three to four months instead of every six.
- What happens in the chair. Your hygienist cleans inside the pockets, measures and records pocket depths, and checks for bleeding points and recession.
- What the visit is for. It's ongoing treatment for a condition being managed, not a preventive check for healthy gums.
Why Every Three Months?
The shorter interval isn't arbitrary. The bacteria that drive periodontal disease can repopulate the pockets around your teeth within roughly three months of a cleaning. A shorter cycle interrupts the process before it restarts.
Dr. Imeni sets your schedule from how quickly you build up plaque and tartar, how deep your pockets are, and how your gums respond between visits. Some patients come more often, and others can gradually lengthen the gap.
Why Did Your Bill Change?
Two things affect what you pay: the fee for the procedure, and how your insurance plan treats it.
Periodontal Maintenance Usually Costs More Than a Cleaning
Because the visit involves more work, it usually has a higher fee than a routine cleaning. Without dental benefits, Delta Dental lists average costs of about $85 to $160 for a standard cleaning and $140 to $220 for periodontal maintenance. Scaling and root planing averages about $180 to $295 per quadrant.
These are published averages, not Smile Design's fees. Your cost depends on your treatment and your plan, so ask for an estimate before your visit.
How Insurance Pays for D4910 vs D1110
Most dental plans treat routine cleanings as preventive care, which is often covered at the highest level. D4910 varies more. Some plans group it with preventive care, while others treat it as a basic or periodontal service, which can mean a deductible and coinsurance.
Other plan rules can change your bill, too. The ADA's guidance on periodontal maintenance claims describes several:
- Frequency limits. Plans cap how many cleanings they pay for, and maintenance visits may share that limit with regular cleanings or have their own.
- An alternate benefit. When plan limits apply, many payers will pay the amount for an adult cleaning instead, which may leave you with a balance.
- Timing rules. Most payers require a waiting period of 8 to 12 weeks after scaling and root planing, and some cover D4910 only within a set window after SRP.
- Documentation. Many payers want an exam, pocket measurements, and a periodontal diagnosis on file first.
The ADA also says dentists should code for the procedure they actually performed. So an office shouldn't report periodontal maintenance as a regular cleaning just to fit a plan's rules.

Who Needs Periodontal Maintenance, and Who Doesn't?
Gum disease is common. The CDC reports that about 4 in 10 U.S. adults age 30 and older had some level of periodontitis in 2009 to 2014.
You Likely Need Periodontal Maintenance If:
- You've had scaling and root planing, LANAP, or gum surgery to treat periodontitis.
- Your dentist has found pockets deeper than the healthy 1 to 3 millimeters, or bone loss on your X-rays.
- Your gum disease is under control, and you want to keep it that way.
A Regular Cleaning Is Usually Enough If:
- Your gums are firm and pink, don't bleed when you brush, and your pockets measure in the healthy range.
- You've never been treated for periodontitis.
- You have early gum inflammation (gingivitis) that hasn't damaged anything below the gumline. MouthHealthy notes that a professional cleaning should be enough at that stage.
There's also a middle option. For widespread moderate or severe gum inflammation without bone loss, the ADA has a separate code, D4346, for a more involved cleaning. It isn't a deep cleaning or periodontal maintenance.
If your gums bleed or look swollen, our guide to keeping your gums healthy explains the warning signs.
Can You Go Back to Regular Cleanings?
Usually not completely. Because periodontal disease can be controlled but not cured, the ADA's code description treats this care as lifelong. What can change is the interval.
If your gums stay stable, Dr. Imeni may gradually lengthen the time between visits.
What Happens If You Skip Periodontal Maintenance?
Periodontal disease returns when maintenance stops. Pockets deepen again, bone loss can continue, and teeth may begin to loosen. Bone that has already been lost doesn't grow back on its own.
If it's been a long time since your last visit, that's not a reason to stay away. Call us, and we'll start from wherever you are.

- Which code will be billed: D1110, D4346, D4910, D4341, or D4342?
- Does my plan cover D4910 as preventive or basic care, and does it share a limit with regular cleanings?
- Is there a waiting period after scaling and root planing?
- What will my visit cost after insurance?
- What should I do at home between visits?

Frequently Asked Questions
What Is the Difference Between Prophylaxis and Periodontal Maintenance?
A dental prophylaxis (D1110) is a preventive cleaning for healthy gums, usually every six months. Periodontal maintenance (D4910) is ongoing care after treatment for periodontitis, with cleaning inside deeper pockets and pocket measurements at every visit.
Is Periodontal Maintenance the Same as a Deep Cleaning?
No. A deep cleaning, or scaling and root planing, is active treatment that clears infection from the root surfaces. Maintenance visits are the upkeep that follows, keeping those treated areas clean and monitored.
How Often Do You Need Periodontal Maintenance?
Most patients are seen every three to four months rather than every six. Your dentist sets the interval from your pocket depths, how fast plaque and tartar build up, and how your gums respond between visits.
Does Insurance Cover Periodontal Maintenance (D4910)?
Many plans cover it, but the rules vary. Some treat D4910 like preventive care, and others treat it as a basic or periodontal service with a deductible and coinsurance. Check your plan's frequency limits and waiting periods.
Why Does Periodontal Maintenance Cost More Than a Cleaning?
The visit involves more work, including cleaning root surfaces inside deeper pockets and recording pocket depths. Delta Dental's published averages without dental benefits are about $140 to $220, compared with $85 to $160 for a standard cleaning.
Can Gum Disease Come Back After Scaling and Root Planing?
Yes. Periodontal disease can be controlled but not cured, so it can return if maintenance visits and home care stop. That's why most patients need ongoing care after a deep cleaning.
What Can I Do at Home Between Visits?
Brush at least twice a day with a soft-bristled brush and fluoride toothpaste, and clean between your teeth every day. Floss picks, interdental brushes, and water flossers all count, so use the one you'll stick with. Our oral hygiene guide has more tips.
Do I Need a Periodontist for Periodontal Maintenance?
Not always. Many general dentists provide it. If you need advanced gum surgery, a periodontist may treat that part, and you can often return to your general dentist for ongoing hygiene visits.
