You went in for a cleaning and came out with a treatment plan for four visits. That is the most common way people meet the phrase “deep cleaning,” and the sticker shock is real, because the office is no longer quoting one procedure. It is quoting four.
This page covers the periodontal deep cleaning, clinically called scaling and root planing. It is a different procedure from the routine six-month cleaning, which our guide to teeth cleaning costs without insurance covers in full. A routine cleaning (CDT code D1110) polishes the tooth surfaces above the gumline and is billed once. A deep cleaning (D4341 or D4342) goes below the gumline to scrape the roots, is billed once per quadrant, and usually needs local anesthetic. All figures below reflect published fee schedules and cost data current as of September 2026.
What Does a Deep Cleaning Cost Without Insurance?
Deep cleaning prices come from three kinds of published sources, and they do not agree, so the table shows the cross-source range. CareCredit’s national cost data and DentalPlans.com’s fee data cover the cash market. State fee schedules from Massachusetts and Wyoming show what a government payer allows, which functions as a floor rather than a market price. Two dental practices that post their full CDT price lists, one in Colorado and one in Massachusetts, show what a real office actually charges.
| Service or code | Low | Average | High |
|---|---|---|---|
| Deep cleaning per quadrant (D4341, four or more teeth) | $150 | $242 | $444 |
| Deep cleaning per quadrant (D4342, one to three teeth) | $165 | $229 | $292 |
| Full-mouth deep cleaning (all four quadrants) | $600 | $968 | $1,776 |
| Scaling with generalized inflammation (D4346, full mouth) | $60 | n/a | $110 |
| Periodontal maintenance (D4910, every 3 to 4 months) | $80 | $132 | $207 |
| Routine cleaning for comparison (D1110) | $81 | $110 | $138 |
The per-quadrant average of $242 and the $185 to $444 spread come from CareCredit’s national cost data for scaling and root planing. DentalPlans.com puts the same procedure at $150 to $350 per quadrant, or $600 to $1,600 for all four. The full-mouth row simply multiplies the per-quadrant numbers by four and blends both sources.
Two published practice fee schedules bracket the cash market neatly. Denver Dental Specialties, a Colorado periodontal practice, posts D4341 at $255 per quadrant and D4342 at $165. Maynard Family Dentists, a Massachusetts general practice, posts D4341 at $386 and D4342 at $292. Same two codes, a $131 gap per quadrant, which is $524 across a full mouth.
The government floor sits far below both. Wyoming Medicaid’s 2026 rates allow $146.25 for D4341 and $121.88 for D4342. Massachusetts allows $134 and $90 under 101 CMR 314.00. Those are not prices you can walk in and pay, but they are useful context when an office quotes you $500 a quadrant.
What Drives the Price
It is billed per quadrant, so “full mouth” means four charges
Your mouth is divided into four quadrants: upper right, upper left, lower right, lower left. Scaling and root planing is coded and priced one quadrant at a time. When an office says “your deep cleaning is $300,” ask whether that is per quadrant or for everything, because the answer changes your bill by roughly $900.
Which code the office bills
D4341 covers four or more teeth in a quadrant. D4342 covers one to three teeth in a quadrant and costs meaningfully less, roughly $110 to $130 less per quadrant on the two practice schedules above. If only a few teeth in a quadrant are affected, D4342 is the correct code, and it is worth confirming which one is on your estimate.
There is also a middle code many offices use. D4346, scaling in the presence of generalized moderate or severe gingival inflammation, full mouth, is meant for inflamed gums without the bone loss that defines periodontitis. It is billed once for the entire mouth, not per quadrant, and it is dramatically cheaper: Massachusetts allows $60 and Wyoming Medicaid allows $109.69.
Anesthesia and the extras around the visit
Local anesthetic is standard for scaling and root planing and is usually bundled into the quadrant fee, but not always. DentalPlans.com lists local anesthesia, antibiotic therapy, and follow-up care among the items that can push the final number up, and notes that without coverage you pay for every step: exam, X-rays, anesthesia, cleaning, and follow-ups. If you need more than local anesthetic, our sedation dentistry cost guide covers those add-ons, and periodontal charting almost always comes with imaging priced in our dental X-ray cost guide.
Where you live
CareCredit’s state-by-state data shows the geographic spread plainly. Alabama averages $200 per quadrant, Iowa $205, and Oklahoma $206 at the low end. California averages $310, Massachusetts $314, and Hawaii $392 at the high end. A cross-country move can change this bill by more than $700.
The maintenance recall that never ends
Once you have been treated for periodontal disease, most offices switch you from the twice-yearly routine cleaning to periodontal maintenance (D4910) every three to four months. DentalPlans.com describes that schedule as the standard follow-up. At three to four visits a year and $80 to $207 per visit, that is a recurring $240 to $828 annually, which over a decade can exceed the original deep cleaning by several times.
Cash Price vs. Insurance
CareCredit reports that dental insurance usually covers around 50% of scaling and root planing, since it is generally considered medically necessary, and that insurers often require X-rays or other documentation of inflammation or bone loss before approving it. Plans also cap how often the procedure can be repeated.
If you are uninsured, the more useful comparison is not insurance but the cash discount. Many offices quote a lower fee when you pay in full at the time of service instead of running a claim, because they skip the claims work and the wait. Ask for that number directly, in writing, before you schedule.
The other trap is the annual maximum. Even people with dental coverage often find a full-mouth deep cleaning plus maintenance eats most of a $1,000 or $1,500 yearly cap, leaving nothing for the crown or extraction that follows. Running the numbers on the cash price first is worth doing either way. Our fair price checker can tell you whether a quote is in the normal band for your area.
How to Pay Less
Split the quadrants across visits and across plan years. Deep cleanings are routinely done two quadrants at a time over two appointments, which DentalPlans.com describes as the typical schedule. That is a legitimate clinical rhythm and it is also a cash-flow lever: two payments of roughly $500 instead of one of $1,000. If you have coverage with an annual maximum, splitting across a calendar year boundary can also reset the cap.
Get the per-quadrant number from three offices. The published fee schedules above differ by $131 per quadrant between a Colorado periodontist and a Massachusetts general dentist. Call three practices, ask specifically for the cash fee for D4341 per quadrant, and write down each answer. General dentists often charge less than periodontists for the same code.
Use a dental school teaching clinic. The University of Washington School of Dentistry states that appointments in its teaching clinics cost roughly 30 to 40 percent less than a local private practice, with supervised dental students doing the work and appointments running two to three times longer. On a $1,200 full-mouth case, that is $360 to $480 saved.
Try a community health center. Federally funded health centers with dental programs charge on a sliding scale tied to household income, and many treat periodontal disease. Our guide to free clinics and sliding-scale care explains how to find one and what to bring to qualify.
Consider a dental savings plan. These are membership discount programs, not insurance, and they typically knock 20% to 50% off the fee at participating offices with no waiting period and no annual maximum. On a full-mouth deep cleaning plus a year of maintenance, that can outrun the membership fee in a single visit.
Negotiate the quote you already have. A dental treatment plan is an estimate, not a bill, and it is negotiable, especially if you are paying cash on the day. Our guide to negotiating medical bills has scripts that work as well at a dental front desk as at a hospital billing office.
The Bottom Line
Budget $150 to $444 per quadrant, or roughly $600 to $1,776 for a full-mouth deep cleaning, then add $80 to $207 every three to four months for maintenance after that. The single most useful question to ask is whether the quote is per quadrant or total, followed by which code the office is billing, since D4346 costs a fraction of four quadrants of D4341.
If the deep cleaning does not close the pockets, the next step is surgical, and the pricing changes again. Our gum surgery cost guide covers osseous surgery, gingivectomy, and laser treatment, and our crown lengthening cost guide covers the procedure that often precedes a crown on a broken-down tooth.
