A periodontal cleaning typically costs between $140 and $220 per visit without insurance. That’s noticeably more than a standard cleaning, which runs $85 to $160, because a periodontal cleaning involves work both above and below the gumline in patients who have been treated for gum disease. But the full picture is more nuanced: the type of periodontal cleaning you need, how many visits are involved, and whether you have insurance all shift the final number significantly.
Periodontal Cleaning vs. Standard Cleaning
A standard dental cleaning, sometimes called a prophylaxis, is preventive. It removes plaque and tartar from the visible surfaces of your teeth and just along the gumline. It’s designed for people with healthy gums or only minor inflammation.
A periodontal cleaning goes deeper. It’s specifically for people who have been diagnosed with gum disease, usually after a measurement called pocket depth comes back at 4 millimeters or more around one or more teeth. Healthy gums sit tightly against the tooth with pockets of 1 to 3 millimeters. Once those pockets deepen, bacteria settle in below the gumline where a regular cleaning can’t reach.
There are actually two distinct procedures people call “periodontal cleaning,” and they carry different price tags.
Scaling and Root Planing (The Initial Deep Cleaning)
Scaling and root planing is the first-line treatment for gum disease. Your dentist or hygienist uses specialized instruments to scrape tartar and bacterial buildup from below the gumline, then smooths the root surfaces so gums can reattach more tightly to the tooth. This is the procedure most people picture when they hear “deep cleaning.”
The cost is typically billed per quadrant of the mouth, meaning your mouth is divided into four sections. Each quadrant generally runs $200 to $350 without insurance, so a full-mouth scaling and root planing can land anywhere from $800 to $1,400 or more. If only one or two quadrants have deep pockets, you’ll pay proportionally less.
Many offices split the procedure across two visits, doing one side of the mouth at a time. Local anesthesia is commonly used to numb the areas being treated, since work below the gumline can be uncomfortable. If you opt for additional sedation beyond standard numbing, expect a separate charge that can push the total higher.
Periodontal Maintenance (Ongoing Visits)
After scaling and root planing, you don’t simply return to regular cleanings. Instead, your subsequent visits are classified as periodontal maintenance. This is the $140 to $220 procedure, and it covers cleaning your entire mouth, both above and below the gumline, with extra attention to areas that previously showed disease.
The American Academy of Periodontology recommends periodontal maintenance at least four times per year, with roughly three months between visits. That schedule helps prevent the disease from progressing again. Some patients eventually move to longer intervals if their gums stabilize, but many people stay on a quarterly schedule indefinitely. At the higher end of the cost range, that works out to roughly $880 per year without insurance, compared to the two standard cleanings per year most people with healthy gums receive.
What Insurance Typically Covers
Most dental insurance plans cover periodontal procedures, but the specifics vary widely. Scaling and root planing is generally covered at 50% to 80% under the “major” or “basic” services category, depending on your plan. Some insurers require documentation of pocket depths of at least 4 millimeters before approving the claim.
Periodontal maintenance coverage is where things get tricky. Some plans cover all four recommended visits per year. Others cover only two periodontal maintenance visits and classify any additional visits as a standard cleaning benefit, which may or may not have remaining coverage. A few plans alternate coverage, paying for a periodontal maintenance visit one quarter and a regular prophylaxis the next, even though the clinical need hasn’t changed. It’s worth calling your insurer before scheduling to understand exactly how many maintenance visits they’ll pay for annually.
Plans also commonly have annual maximums, often $1,000 to $2,000 per year. If you need full-mouth scaling and root planing plus follow-up maintenance in the same year, you could hit that cap quickly, leaving remaining visits as out-of-pocket costs.
Ways to Reduce Your Out-of-Pocket Cost
If you don’t have dental insurance or your coverage falls short, several options can bring the price down. Dental schools often offer periodontal cleanings at 50% to 70% of private-practice rates, performed by supervised students or residents. Community health centers with sliding-scale fees are another option, particularly for lower-income patients.
Many private dental offices offer in-house membership plans for uninsured patients. These typically charge an annual fee (often $200 to $400) and include a set number of cleanings and exams at discounted rates. If you know you’ll need quarterly periodontal maintenance, a membership plan can cut costs meaningfully over the year. Some offices also offer payment plans that let you spread the cost of scaling and root planing over several months without interest.
Why Skipping It Gets More Expensive
Gum disease doesn’t reverse on its own once it progresses past gingivitis. Without treatment, pockets continue to deepen, bone supporting the teeth breaks down, and teeth can loosen or require extraction. The cost of replacing a single tooth with an implant typically runs $3,000 to $5,000, and more advanced periodontal surgeries like gum grafting or bone grafts range from $600 to $3,000 per area. Compared to those numbers, quarterly maintenance at $140 to $220 per visit is a fraction of the cost of letting the disease advance unchecked.
