A deep teeth cleaning without insurance typically costs $235 to $303 per quadrant of your mouth. Since your mouth is divided into four quadrants, a full-mouth deep cleaning runs between $940 and $1,212 if all four areas need treatment. That total doesn’t include the exam and X-rays required beforehand, which can add a few hundred dollars more.
What a Deep Cleaning Actually Involves
A deep cleaning, formally called scaling and root planing, is different from the standard cleaning you get at a checkup. A regular cleaning removes plaque and tartar above the gumline. A deep cleaning goes below the gumline, scraping bacteria and hardened deposits off the roots of your teeth and smoothing the root surfaces so your gums can reattach.
Your dentist will typically recommend this procedure when the pockets between your gums and teeth measure 4 millimeters or deeper, according to the American Dental Association. Healthy pockets are usually 1 to 3 millimeters. Deeper pockets mean bacteria have worked their way down and started damaging the bone and tissue that hold your teeth in place. Left untreated, this progresses to periodontitis, which can lead to tooth loss.
Full Cost Breakdown Per Quadrant
Dentists bill deep cleanings by quadrant rather than as a single flat fee. Your mouth is divided into four sections: upper left, upper right, lower left, and lower right. Each quadrant costs $235 to $303, so the math depends on how many quadrants are affected.
- One quadrant: $235 to $303
- Two quadrants: $470 to $606
- Three quadrants: $705 to $909
- Four quadrants (full mouth): $940 to $1,212
Not everyone needs all four quadrants treated. If gum disease is concentrated on one side of your mouth, your dentist may only recommend two quadrants, cutting the bill roughly in half. The procedure is often split across two visits, with two quadrants done per appointment, though some offices will complete all four in a single session.
Costs Beyond the Cleaning Itself
Before a deep cleaning can happen, you’ll need a comprehensive exam and X-rays so your dentist can measure pocket depths and assess bone loss. These diagnostic costs are separate from the cleaning fee and add to your total bill.
A full-mouth series of X-rays averages $226, with prices ranging from $175 to $428 depending on your location and the dental office. Bitewing X-rays, which capture a smaller area, average around $65. A panoramic X-ray, which gives a broad view of your entire jaw, averages $200. Your dentist will choose the type based on what they need to see. Add in the exam fee, and you could be looking at an extra $200 to $400 before the cleaning even starts.
Local anesthesia is commonly used during deep cleanings because the instruments go below the gumline. Some offices include this in the per-quadrant price, while others bill it as a separate line item. Ask before your appointment so you aren’t surprised.
Ongoing Costs After Treatment
A deep cleaning isn’t a one-time fix. Once you’ve had scaling and root planing, your regular cleanings are replaced by periodontal maintenance visits, typically every three to four months instead of every six. These visits involve cleaning above and below the gumline to keep gum disease from returning.
Periodontal maintenance costs $140 to $220 per visit without insurance. That’s noticeably more than a standard cleaning, which runs $85 to $160. Over the course of a year, three or four maintenance visits add $420 to $880 to your annual dental costs. This is worth factoring into your budget because periodontal maintenance is an ongoing commitment, not a temporary follow-up.
Ways to Lower the Price
Dental schools offer some of the steepest discounts. Students perform the procedures under close faculty supervision, and the savings can be dramatic. At Indiana University Fort Wayne’s dental clinic, for example, scaling and root planing costs $110 per quadrant for four or more teeth, and $75 for one to three teeth. That brings a full-mouth deep cleaning well under $500. The trade-off is longer appointment times, since students work more slowly, and waitlists can be weeks or months long.
Dental discount plans are another option. These aren’t insurance but membership programs that give you reduced rates at participating dentists. Aspen Dental’s savings plan, for instance, offers 20% off gum disease treatment and periodontal care. On a $1,000 deep cleaning, that’s roughly $200 in savings, and the membership itself typically costs $100 to $200 per year.
Community health centers that operate on a sliding-fee scale base your cost on income. The federal Health Resources and Services Administration maintains a directory of these centers. Some nonprofit dental clinics and charitable organizations also provide periodontal services at reduced rates or for free during outreach events.
If none of those options work, many private dental offices offer payment plans or accept third-party financing through services like CareCredit, which lets you spread the cost over several months. Some offices also discount the total if you pay in full upfront. It never hurts to ask.
