Deep Cleaning Cost in 2026

Build your real SRP total

A per-quadrant sticker price is not your bill. Your bill is quadrants treated × the per-quadrant fee, plus the recurring maintenance schedule that follows active treatment — the line no other cost page totals. Build yours:

Deep cleaning cost by scope (2026 benchmarks)

The biggest driver of your bill is how much of your mouth needs treatment and how heavy the tartar is. The chart below puts the whole cost ladder on one scale — from a routine cleaning, to scaling and root planing per quadrant, to a full mouth, to the recurring maintenance you are signed up for afterward. Ranges are compiled from published payer and provider fee data (2024-2026) and AAP guidance, deliberately free of any single clinic's commercial framing.

How SRP is billed: by quadrant, by CDT code

"Deep cleaning" is not one charge. Your mouth is split into four quadrants (upper right, upper left, lower right, lower left), and each is billed separately depending on how many teeth in it have disease:

• D4341 — SRP, four or more teeth per quadrant. The standard deep-cleaning code. This is what most full-mouth quotes are built from.
• D4342 — SRP, one to three teeth per quadrant. Used for a localized quadrant; it is billed lower than D4341 because fewer teeth are treated.
• D1110 — adult prophylaxis. The routine cleaning you are not getting if you need SRP. It only cleans above the gumline.
• D4346 — full-mouth scaling for generalized gum inflammation. The in-between code: more involved than a routine D1110 cleaning ($75-$200 published range) but not yet quadrant-based SRP. It's used when gums are inflamed throughout without the bone loss that justifies D4341 — and it's the newest code on this list, so insurance handling varies more than for the others. Confirm how your plan classes it before treatment.
• D4381 — localized antibiotic placed into a pocket (e.g. Arestin), billed per tooth. This is the add-on line discussed under optional add-ons below: reasonable for a few stubborn 6mm+ pockets, worth questioning when it appears next to every tooth on the plan.

This is why two quadrants on the same invoice can cost different amounts: a quadrant with all teeth affected (D4341) is priced above a quadrant with only two affected teeth (D4342).

Why a deep cleaning costs more than a regular cleaning

A regular cleaning runs roughly $75-$200 for your whole mouth. SRP costs several times that for one reason: it is treatment for a disease, not maintenance.

Aspen Dental's published 2026 data puts the per-quadrant average near $289, with light-calculus quadrants around $210 and heavy calculus up to $435 — the spread the chart above captures.

Light vs heavy calculus: where your quote lands

Two patients can both "need a deep cleaning" and get very different prices. The variable is how much hardened tartar (calculus) sits below the gumline and how deep the pockets are.

• Light calculus, shallow 4mm pockets → lower end, roughly $150-$280 per quadrant.
• Heavy calculus, 5mm+ pockets with bone loss → upper end, roughly $280-$435 per quadrant, because it takes more time and instrumentation.

A dentist who measures your probing depths (the millimeter numbers called out during the exam) and shows you the X-ray bone levels is justifying which end you fall on. Ask to see both.

Insurance: typically ~80% basic, but watch the annual maximum

Unlike the routine cleaning most plans cover at 100%, SRP sits in the basic/periodontal tier:

• Coverage — commonly 50-80% after your deductible, once medical necessity (4mm+ pockets, bone loss) is documented.
• Annual maximum — a full-mouth case can eat much of a $1,000-$2,000 yearly cap, squeezing out other needed work.
• Frequency limit — usually one SRP per quadrant every 24 months.
• Two-calendar-year timing — splitting quadrants across a year-end boundary can tap two annual maximums.
• Pre-authorization — ask your office to submit one so you know your share before you commit.

The recurring cost nobody quotes: periodontal maintenance

This is the line most cost guides skip. After SRP you do not return to free regular cleanings — you are moved to periodontal maintenance (D4910), typically every 3-4 months at $115-$300 a visit.

Here is the math: at four visits a year you are looking at roughly $460-$1,200 annually. But most plans fund only two cleanings per year, so visits #3 and #4 are usually out of pocket — about $230-$600 every year, indefinitely. That recurring figure often outweighs the one-time SRP within a few years, and it is the real long-term cost of a deep cleaning.

What happens — and what it costs — if you skip it

Gum disease does not pause. Untreated periodontitis keeps deepening pockets and destroying the bone that holds your teeth, usually painlessly until it is advanced. The cost escalation is steep:

Saving the teeth you have for $676-$1,408 is dramatically cheaper than extracting and replacing them — one of the clearest cost cases in dentistry.

Optional add-ons you can decline

Not every line on an SRP quote is mandatory. These are commonly upsold and are reasonable to question:

• Localized antibiotic (e.g. Arestin) — best reserved for specific stubborn 6mm+ pockets, not "every tooth." Whole-mouth application can add hundreds to over a thousand dollars.
• Laser bacterial reduction — frequently $50-$150 and often not covered by insurance.
• Perio irrigation — much of this can be maintained at home with a water flosser.

A fair script: "I consent to the scaling and root planing today; I'd like to decline the laser and the antibiotic for now and reassess at my follow-up once I've healed."

What a deep cleaning is, step by step

Scaling and root planing (SRP) is a two-part procedure, not a deeper version of a regular cleaning. Scaling removes plaque, tartar and bacteria from the tooth surface, including below the gumline where a routine cleaning cannot reach. Root planing then smooths the exposed root surface so plaque struggles to reattach and the gum tissue can heal back against the tooth.

The condition that triggers it is periodontitis, not simple gingivitis. Gingivitis is early, reversible inflammation at the gumline that a regular cleaning (D1110) and better home care usually resolve on their own. Periodontitis is the stage where pockets between tooth and gum reach 4mm or deeper and bone loss shows on X-rays — the clinical line that separates a routine-cleaning claim from an SRP claim on most insurance policies. Our gum disease guide covers how the two stages are staged and billed in more detail.

The appointment itself follows a set order. The area being treated is numbed with local anesthesia first, so the visit is manageable rather than painful. The clinician then works through scaling and root planing one quadrant at a time — upper right, upper left, lower right, lower left — using hand instruments, an ultrasonic scaler, or both. Treating the full mouth this way commonly takes one to four visits rather than a single sitting, partly so the entire mouth is never numbed at once and partly so each section gets full attention.

Once SRP is complete, the maintenance schedule changes for good. Instead of returning to twice-yearly cleanings, most patients move to periodontal maintenance (code D4910) roughly every three to four months — a recurring visit built to keep pockets from reopening rather than a one-time fix. How the per-quadrant SRP fee and the ongoing maintenance visits compare in cost is broken out in the calculator above and the ranges on this page.

Full mouth debridement (D4355) vs scaling and root planing

Full mouth debridement (CDT code D4355) is a "gross removal" of heavy, hardened tartar from above the gumline, priced at $100-$260 nationally. It exists to solve one problem: when calculus is thick enough to block a periodontal probe, the dentist cannot measure pocket depth or read X-rays accurately, so no diagnosis is possible. Clearing that buildup is the whole job — D4355 is a diagnostic enabler, not a treatment for gum disease itself.

That is why it is rarely the final bill. In practice, D4355 is step one of an episode: the debridement visit, then a second appointment for a comprehensive exam (D0150) once the inflammation settles, and often scaling and root planing (D4341) once that exam finds periodontitis — covered in full in our gum disease guide. Patients who start with a debridement can end up closer to $700-$2,000+ across the full course of care, not the $100-$260 headline alone.

Two billing rules trip patients up. Most insurers cover D4355 only once every 3-5 years, sometimes once per lifetime, treating a repeat request as a sign of lapsed care rather than ongoing treatment. And most plans will not pay for a comprehensive exam or a routine cleaning (D1110) billed the same day as the debridement — the logic being that a mouth still covered in heavy tartar cannot yet be properly examined or classed as regularly maintained. Confirm both limits with your plan before scheduling.

Where it sits relative to the rest of a cleaning history: prophylaxis (D1110) maintains already-healthy gums above the line; debridement clears heavy buildup so a diagnosis becomes possible; scaling and root planing treats disease below the gumline once diagnosed; periodontal maintenance keeps it from returning afterward. The routine end of that ladder, with the two-per-year insurance limit priced in, is on the teeth cleaning cost page.
