How Much Does a Deep Cleaning (Scaling & Root Planing) Cost?

Editorially reviewed by the Dental.me Editorial Team · Updated July 2026

A deep cleaning, known clinically as scaling and root planing, typically costs $150 to $350 per quadrant in the United States. That puts a full-mouth treatment (all four quadrants) at roughly $600 to $1,800 before insurance. With dental insurance, deep cleaning is usually covered as a periodontal procedure at 50% to 80%, dropping your out-of-pocket cost to about $200 to $600.

That range is wide, and the reason matters to your wallet. A deep cleaning isn’t one flat procedure. It’s priced by the quadrant, scaled to how much disease your dentist actually finds, and billed under codes your insurance treats nothing like a routine cleaning. Nail down those three details and you can predict your bill within about a hundred dollars.

What is a deep cleaning, and how is it different from a regular cleaning?

A regular cleaning (prophylaxis) polishes the visible tooth and the gumline. A deep cleaning goes underneath it. Your hygienist or dentist scales hardened plaque and tartar off the tooth roots, then smooths (planes) the root surface so the gum can reattach and the pocket can shrink back down.

You need it once gum disease has moved past gingivitis into periodontitis, which usually shows up when pocket depths measure 4 millimeters or deeper. Ignore those pockets and they trap bacteria, the bone around your teeth erodes, and teeth start to loosen. Scaling and root planing is the standard first-line treatment to stop that slide before it costs you a tooth.

The pricing follows the anatomy. Your mouth splits into four quadrants: upper right, upper left, lower right, lower left. A deep cleaning is billed per quadrant, and most people who need one need it in more than a single quadrant. That, more than anything, is what drives the final number.

How much does a deep cleaning cost per quadrant vs. full mouth?

Here’s the honest range. These are typical US figures, not our data (we track dentists and ratings, not procedure prices), and your quote will shift with your location and the severity your dentist documents.

Two codes do most of the heavy lifting on your bill. D4341 is scaling and root planing for a quadrant with four or more teeth involved. D4342 covers a quadrant with only one to three teeth involved, and it costs less. If your dentist finds disease in only part of your mouth, you pay for those quadrants alone. A two-quadrant treatment might land around $300 to $700 instead of the full-mouth figure.

What makes a deep cleaning cost more or less?

Five things move the number more than the rest combined:

• How many quadrants need treatment. One quadrant versus four is a 4x swing, and severity dictates that, not preference.
• Severity per quadrant. Deeper pockets and heavier tartar push you into the full D4341 code instead of the lighter D4342.
• Who does it. A general dentist usually charges less than a periodontist (a gum specialist). Advanced cases tend to get referred out, and specialist fees run higher.
• Where you live. Urban and coastal practices sit above the national midpoint. Smaller markets often come in under it.
• Add-ons. Local antibiotics placed in the pocket (like minocycline microspheres) run about $35 to $85 per site, and a full-mouth debridement before the real cleaning can tack on $75 to $150. These are common and legitimate. They’re also line items worth asking about before you sit in the chair.

Does dental insurance cover a deep cleaning?

Usually, yes, and this is where a scary sticker price often gets cut in half. Most dental PPO plans classify scaling and root planing as a basic or major periodontal service and cover it at 50% to 80% after your deductible, because it treats a documented disease rather than a cosmetic upgrade.

Watch for the catches:

• Annual maximum. Most plans cap total yearly payouts around $1,000 to $2,000. A full-mouth deep cleaning plus follow-up can eat a big slice of that.
• Frequency limits. Insurers often won’t pay to scale and root plane the same quadrant more than once every 24 to 36 months.
• Documentation. Coverage typically requires charted pocket depths of 4mm+ and often X-rays showing bone loss. A dentist who documents properly gets your claim paid. One who doesn’t leaves you writing an appeal.
• Maintenance after. Once you’ve had a deep cleaning, you usually move to periodontal maintenance (code D4910) every three to four months instead of standard six-month cleanings, and that recurring visit costs more than a routine cleaning ($115 to $200 vs. $75 to $200).

Is a deep cleaning worth it, or is my dentist upselling?

Fair question, and a common one. The honest answer: a deep cleaning is one of the more genuinely necessary procedures in dentistry when the numbers back it up, and one of the more over-recommended when they don’t.

The tell is documentation. A dentist recommending scaling and root planing should be able to put a periodontal chart in front of you, with pocket depths (the millimeter readings), bleeding points, and usually X-rays showing bone loss. If pockets are consistently 4mm or deeper and they bleed, treatment is appropriate, and stalling costs you bone you can’t grow back. If your gums look healthy, pockets read 1 to 3mm, and you’re still being told you need a full-mouth deep cleaning, that’s your cue to get a second opinion.

You’re allowed to ask: “What are my pocket depths? Which quadrants, and why this code?” A good practice welcomes the question. To compare practices or find a periodontist for a second read, browse dental specialties or search for a dentist near you to see options ranked independently.

How can you lower the cost of a deep cleaning?

• Ask for a written treatment plan with codes. Knowing whether each quadrant is billed D4341 or D4342 lets you check it against your insurance line by line.
• Split treatment across two benefit years if you’re near your annual max: two quadrants in December, two in January. Only do this if your dentist agrees it’s clinically safe to wait.
• Ask about an in-house membership plan if you’re uninsured. Many practices offer one for a flat annual fee that discounts periodontal work 15% to 25%.
• Compare a general dentist vs. a periodontist for straightforward cases. A moderate case handled well by a general dentist can cost meaningfully less than a specialist.
• Don’t skip the maintenance visits afterward. It sounds backwards, but those recurring cleanings protect the money you just spent. Slide back into disease and you’re paying for the deep cleaning all over again.

Frequently asked questions

How much does a full-mouth deep cleaning cost without insurance?

Typically $600 to $1,800 for all four quadrants, depending on severity, your location, and whether a general dentist or periodontist performs it. Cases needing only two quadrants often run $300 to $700.

Why is a deep cleaning so much more expensive than a regular cleaning?

A regular cleaning is a single preventive visit priced at roughly $75 to $200. A deep cleaning is a therapeutic treatment billed per quadrant, often requires local anesthesia, takes more chair time, and treats active disease below the gumline. Four quadrants of treatment simply involve far more work.

Does insurance cover scaling and root planing?

Most dental PPO plans cover it at 50% to 80% as a periodontal service, subject to your deductible, annual maximum, and a frequency limit (often once per quadrant every 24 to 36 months). Coverage usually requires charted pocket depths of 4mm or more.

Do I need all four quadrants done?

Only the quadrants with disease. If pockets and bone loss appear in every quadrant, all four get treated; if only part of your mouth is affected, you pay only for those quadrants. Ask to see your periodontal chart to confirm.

What happens if I skip a recommended deep cleaning?

Untreated periodontitis progresses. Pockets deepen, bone erodes, gums recede, and teeth can loosen or be lost. The bone loss is permanent, and early treatment is far cheaper than later options like gum surgery or implants.

How often will I need deep cleanings?

Scaling and root planing is usually a one-time treatment per episode of disease. After it, you move to periodontal maintenance every three to four months to keep pockets stable, rather than repeating the full deep cleaning.
