All-on-4 Cost by State: Reading the U.S. Averages Before You Shop Around

If you have started pricing full-arch implants, you have probably noticed that two clinics a few hours apart can quote very different numbers. Part of that gap is geography. Rent, staff wages, lab costs and local competition all show up in the fee schedule. A state-level average will not tell you what your own mouth will cost, but it does tell you whether a quote in front of you sits near the local middle, well above it, or suspiciously far below it.

This guide walks through one of the few public state-by-state datasets for All-on-4 pricing, explains what it measures, and shows how to turn it into a practical yardstick for your own search.

Where the state numbers come from

In April 2026, CareCredit (2026) published All-on-4 averages for every U.S. state and the District of Columbia, drawn from a 2024 Synchrony/ASQ360 study of U.S. dental practices. The national average in that dataset is $15,176 (USD), with a published range of $11,640 to $27,500 (USD).

Two details matter before you use any of it:

• It is practice-reported pricing, not your bill. The survey captures what practices said they charge. It is not a database of paid claims, and it does not adjust for case difficulty.
• The page does not say whether the figure is per arch or per mouth. Most full-arch pricing in the U.S. is discussed per arch, but the source does not state it. When you compare a quote against these numbers, confirm with the clinic whether their figure covers one arch or both.

The spread: highest and lowest state averages

Across the 51 figures, the lowest average is Mississippi at $12,642 and the highest is Hawaii at $22,989 (all USD, 2024 data via CareCredit). That is a gap of roughly $10,300 for what is nominally the same named treatment.

Source for every figure in this table: CareCredit, All-on-4 cost by state (2026 publication of 2024 data, USD).

Most states sit below the national average

Here is a detail that is easy to miss. When we counted the 51 state-level figures, 33 were below the $15,176 national number and 18 were above it. If you line up all 51 from cheapest to most expensive, the one in the middle is Pennsylvania at $14,615.

In plain terms, a handful of expensive markets pull the national figure upward. If you live in a lower-cost state and compare a local quote only to the national average, you may think you are getting a deal when you are simply paying the going rate where you live. The state number is the better local reference point.

A few mid-sized markets for reference

• Texas: $13,720
• Ohio: $14,291
• Florida: $15,132
• Arizona: $15,439
• New York: $16,264

Why the same treatment prices differently across state lines

The survey does not break down the reasons for the gaps, so treat the following as the usual cost structure of a dental practice rather than a measured explanation:

Overhead

Commercial rent, insurance, equipment financing and utilities vary sharply between, say, a suburban Midwest office and a downtown coastal one. Full-arch cases also tie up surgical suites and chair time for hours, so space costs land heavily on this procedure.

Staff and specialists

A full-arch case can involve a surgeon, a restorative dentist, an anesthesia provider, assistants and lab technicians. Wages for all of them follow the local labor market.

Lab and logistics

Remote areas, including Hawaii and Alaska, can face higher costs to ship materials, use outside labs or bring in specialists. A practice that runs its own in-house lab has a different cost structure from one that sends every bridge out.

Competition

Metro areas with many implant-focused practices can push headline prices down, while a region with one or two providers has less pressure to compete on price.

How to use a state average without being fooled by it

An average is a reference line, not a target. Use it in three ways.

1. Flag quotes that are far outside the local norm

If a quote lands well above your state figure, ask what is driving it: zirconia instead of acrylic, a six-implant plan, grafting, IV sedation, a specialist team. Those can be legitimate. If a quote lands far below it, read the scope carefully. A very low number often covers surgery and a temporary bridge, with the final prosthesis priced later.

2. Normalize the scope before comparing

The state average does not tell you what was included in the price practices reported. Your own comparison should hold scope constant: same arch count, same extractions, same imaging, same sedation, same final bridge material, same follow-up.

3. Do not assume a neighboring state is automatically cheaper

Driving across a state line can make sense, but the savings shrink once you count fuel, hotel nights, time off and return visits for adjustments. Some neighboring states are close in price. Kansas ($13,418) and Missouri ($13,483), for instance, are less than $100 apart in the dataset.

Where travel abroad fits into the comparison

Many people pricing full-arch work look at both an in-state option and a treatment-abroad option. The state averages make that comparison more honest. A patient in Hawaii and a patient in Mississippi are starting from very different home benchmarks, so the potential savings from traveling are not the same for both. Someone in a high-cost state has more room to absorb flights, a recovery week and a possible second trip. Someone in a lower-cost state has less.

Whatever the home figure, the abroad option has to be compared as a complete trip: treatment scope, travel, lodging, time away, the number of visits the protocol needs, and what happens if something needs attention after you are home.

A worked example: the same plan in three states

Suppose three people need the same thing: one arch, four implants, a fixed bridge. One lives in Mississippi, one in Pennsylvania and one in California. Using only the published averages, their starting reference points look like this:

The differences in that table are simple arithmetic on the CareCredit (2026) figures, not separate data. Notice how the same $15,000 quote tells a different story depending on where you live. In one state it is above average; in another it is a bargain that may hide a missing line item. That is the main reason to anchor to your state, not the country.

If you need both arches, do not simply double the number. Some clinics discount a full-mouth case, some price each arch independently, and the upper and lower arches can differ in difficulty. Ask for each arch to be itemized.

Questions to ask a clinic once you know your state benchmark

• Is this price for one arch or both?
• Does it include extractions, 3D imaging and sedation, or are those billed separately?
• Is the bridge in this price the temporary, the final, or both?
• What material is the final bridge, and what does an upgrade cost?
• How many visits are included, and what does an extra adjustment visit cost?
• What would make this price change after the scan?

Asking these with your state figure in hand turns a vague conversation about "a good price" into a line-by-line explanation of why this quote is where it is.

What the state data cannot tell you

• Your anatomy. Bone volume, gum health and the condition of any remaining teeth drive the plan far more than ZIP code.
• Material choice. The average does not separate acrylic hybrids from zirconia bridges.
• Who does the work. A general dentist, a prosthodontist, an oral surgeon or a team of specialists may all charge differently.
• Inflation since 2024. The underlying study is from 2024. Prices quoted today may have moved.

Use the state number to ask better questions, not to decide what treatment you need. That decision belongs with a licensed clinician who has examined you and reviewed 3D imaging.
