A full-mouth deep cleaning typically costs between $600 and $1,500 without insurance, though the final number depends heavily on where you live and how many teeth need treatment. Most dental offices bill this procedure per quadrant (one quarter of your mouth), with each quadrant ranging from $100 to $500. That means the total climbs quickly once all four quadrants are involved.
Cost Per Quadrant and Full Mouth
Deep cleanings are billed by the quadrant because the work is intensive, often requiring two separate appointments to complete the full mouth. A 2025 national survey of dentist charges puts a single quadrant between $100 and nearly $500. If your dentist treats all four quadrants, you’re looking at roughly $400 to $2,000 for the complete procedure. The wide range reflects differences in geography, the severity of gum disease, and whether you need numbing.
Your dentist may also bill differently depending on how many teeth in a given quadrant need treatment. If only a few teeth in one section are affected, the office can use a partial-quadrant billing code, which costs less than treating the full quadrant. This is worth asking about, because it can meaningfully reduce the total if your gum disease is limited to certain areas.
Why Location Changes the Price So Much
Geography is one of the biggest cost drivers. Illinois has the highest average at about $365 per quadrant, which translates to nearly $1,500 for a full mouth. Mississippi and Missouri average around $355, and states like Utah and North Carolina sit above $340. Texas and Florida land in the top ten at $315 and $300 per quadrant, respectively.
On the lower end, Hawaii averages $155 per quadrant, and Colorado, Alaska, and Arkansas fall between $170 and $174. California averages $215, but the range within the state runs from $155 in rural counties to $275 in Los Angeles or San Francisco. States with more dentists per capita, like Colorado, tend to have lower prices because competition keeps fees in check. States with high overhead costs for rent, wages, and malpractice insurance, like Illinois, push prices up.
Add-Ons That Increase the Bill
The base price covers scaling and root planing, the two-part process of scraping bacteria and hardened deposits from below the gumline and then smoothing the tooth roots so gums can reattach. But several common extras can raise your total.
- Local anesthesia: Many patients need numbing for comfort during a deep cleaning. If your office charges separately for anesthesia rather than bundling it in, expect the cost to increase noticeably.
- Localized antibiotics: Your dentist may place a small antibiotic directly into infected gum pockets after cleaning them. This runs $30 to $75 per tooth treated, and if multiple teeth need it, the cost adds up fast.
- Additional imaging: X-rays taken before or during the procedure to assess bone loss are sometimes billed separately from the cleaning itself.
Ask your office for an itemized estimate before scheduling. The quoted price for a “deep cleaning” may or may not include these extras.
What Triggers the Recommendation
A deep cleaning isn’t a routine procedure. Your dentist recommends one when there are clinical signs of gum disease: pockets between your gums and teeth measuring 4 millimeters or deeper, bone loss visible on X-rays, or gums that bleed during probing. Healthy gums typically have pockets of 1 to 3 millimeters. Once those pockets deepen, a standard cleaning can’t reach the bacteria and tartar trapped below the gumline.
If your dentist measures pockets at 4 mm or greater in multiple areas, you’ll likely be told you need the full-mouth treatment across all four quadrants. If only one or two areas are affected, you may only need one or two quadrants treated, cutting your cost in half or more.
The Ongoing Cost After Treatment
A deep cleaning isn’t a one-time fix. Once you’ve been treated for gum disease, you’ll need periodontal maintenance visits instead of standard cleanings. These visits happen every three to four months rather than every six, and they involve targeted cleaning below the gumline at specific problem sites. A standard adult cleaning runs about $132 at the median. Periodontal maintenance visits cost more and occur more frequently, so your annual dental spending will increase compared to what you were paying before.
Skipping these follow-up visits allows gum disease to return, which can eventually mean repeating the deep cleaning or facing more invasive treatment. Factoring in these recurring costs gives you a more realistic picture of the total investment.
Prices Are Still Rising in 2025
Dental costs have been climbing steadily. ADA data from the second quarter of 2025 shows consumer dental spending is up 3% so far this year, and the costs dental offices pay for equipment, supplies, and staff wages have risen even faster, with most practices reporting increases above 5% since January. Dentists expect prices to continue rising over the next six months. If you’re comparing quotes you found online from a year or two ago to what your dentist just quoted, this inflationary pressure explains part of the gap.
