A deep teeth cleaning, officially called scaling and root planing, costs between $600 and $1,600 for a full mouth without insurance. The national average is about $242 per quadrant, with individual quadrants ranging from $185 to $444 depending on your location and the severity of gum disease. Your mouth is divided into four quadrants for billing purposes, so the total depends on how many areas need treatment.
Cost Per Quadrant vs. Full Mouth
Dentists don’t bill a deep cleaning as a single flat fee. Instead, they charge by the quadrant, and you may not need all four treated. If gum disease is limited to one side of your mouth, you might only pay for one or two quadrants. The price per quadrant varies based on geography, the dental practice, and how many teeth in that quadrant are affected. When fewer than four teeth in a quadrant need treatment, your dentist may bill it as a “partial quadrant,” which can cost less than a full one.
Here’s a rough breakdown for out-of-pocket costs without insurance:
- 1 quadrant: $185 to $444
- 2 quadrants: $370 to $888
- Full mouth (4 quadrants): $600 to $1,600
Extra Charges That Add to the Bill
The per-quadrant price covers the scaling and root planing itself, but a few common add-ons are billed separately. Local anesthesia, which most patients need because the cleaning goes below the gumline, is its own line item. Expect roughly $70 to $90 per application. If your dentist places a localized antibiotic directly into a deep gum pocket after cleaning, that runs around $160 to $180 per tooth. Not everyone needs it, but for pockets that are especially deep or infected, your dentist may recommend it.
You’ll also need X-rays and a periodontal exam before the procedure. Many offices include these in a new-patient visit or as part of your diagnostic workup, but if you’re paying out of pocket, factor in an additional $100 to $300 for imaging and the exam that leads to the deep cleaning recommendation.
What Insurance Typically Covers
Most dental insurance plans cover scaling and root planing, but the specifics vary widely. Coverage depends on the employer-funded policy rather than a universal standard, so there’s no single reimbursement percentage that applies everywhere. That said, many plans classify deep cleanings under “basic” or “major” procedures and cover 50% to 80% of the cost after your deductible.
There are a few common restrictions to watch for. Many insurers limit deep cleaning to once per quadrant every 24 months. Some plans won’t cover more than two quadrants on the same day, even if your dentist recommends all four. And if there’s no X-ray evidence of bone loss or significant gum attachment loss, the claim is likely to be denied. Your dentist’s office will usually submit periodontal charting and radiographs with the claim to justify the treatment, but it’s worth confirming your plan’s requirements before scheduling.
Why It Costs More Than a Regular Cleaning
A standard dental cleaning (prophylaxis) runs $85 to $160 and focuses on removing plaque and tartar from the visible surfaces of your teeth, above the gumline. It’s preventive care for healthy mouths. A deep cleaning is a therapeutic procedure for gum disease. Your dentist or hygienist uses hand instruments or ultrasonic tools to clean below the gumline, scraping hardened deposits off the root surfaces of your teeth. The second part, root planing, smooths those root surfaces so bacteria have a harder time reattaching.
The procedure takes longer, often requires numbing, and targets areas that a regular cleaning can’t reach. That’s why the price difference is significant.
How Dentists Decide You Need One
During a dental exam, your dentist or hygienist measures the depth of the space between each tooth and the surrounding gum tissue using a small probe. In a healthy mouth, these pockets measure 1 to 3 millimeters. Pockets deeper than 4 millimeters suggest gum disease. Once pockets reach 5 millimeters or more, routine brushing and standard cleanings can’t reach the bottom, and bacteria continue to cause damage. That’s when deep cleaning becomes necessary.
Your dentist will also look at X-rays for signs of bone loss around the teeth. The combination of deep pockets, bone loss, and visible tartar below the gumline is what triggers the recommendation. This isn’t a judgment call or an upsell. Left untreated, the infection progresses, pockets deepen, and teeth can loosen.
The Ongoing Cost After Treatment
A deep cleaning isn’t a one-and-done fix. After scaling and root planing, you’ll shift from standard cleanings to periodontal maintenance visits, typically every three to four months instead of the usual six. These maintenance cleanings cost $140 to $220 without insurance, falling between a regular cleaning and a deep cleaning in price. They involve cleaning above and below the gumline to prevent gum disease from returning.
This ongoing schedule is easy to overlook when budgeting for a deep cleaning, but it’s a real part of the total cost. Over a year, three to four periodontal maintenance visits add $420 to $880 to your annual dental expenses before insurance. Some plans cover periodontal maintenance at the same rate as preventive cleanings, while others classify it differently with lower reimbursement. Check your specific policy so you’re not surprised at the first follow-up visit.
Ways to Reduce Your Out-of-Pocket Cost
If you don’t have dental insurance, many offices offer in-house membership plans or discount programs that reduce the per-quadrant price by 15% to 30%. Dental schools are another option. Supervised students perform scaling and root planing at significantly reduced rates, though appointments take longer.
If you do have insurance, schedule a pre-treatment estimate. Your dentist’s office submits the proposed treatment codes to your insurer, and you get a breakdown of what’s covered before committing. This avoids surprises, especially around frequency limits or quadrant restrictions. Some patients also split treatment across two visits, doing two quadrants at a time, which some insurers actually prefer and which spreads the co-pay over two billing cycles.
