How Much Are Cavity Fillings? | Real Costs By Tooth

If you are typing “how much are cavity fillings?” into a search box, you likely want a solid price range before you book an appointment. Dental bills can feel unclear, and it is easy to worry about extra charges that show up only when you are checking out.

There is no single flat price for every tooth, but there are clear patterns. Basic metal or tooth-colored fillings often fall between $100 and $400 per tooth before insurance, while ceramic or gold work can climb toward $1,000 or more. The gap comes from the material, the tooth, the size of the cavity, and how your dental plan handles fillings.

How Much Are Cavity Fillings Per Tooth On Average?

Across many cost surveys and fee guides, simple fillings in one tooth tend to start just above one hundred dollars. For common materials such as amalgam and composite resin, many clinics list fees in the low to mid hundreds per tooth when no insurance is involved.

GoodRx and CareCredit cost guides that draw on dentist fees and claim data describe a broad range from around $100 up to roughly $1,150 per tooth in the United States, with higher numbers for large ceramic or gold restorations. Those figures line up with American Dental Association fee surveys that place small amalgam fillings near the mid-$100 mark and small composite fillings somewhat above that level.

Filling Material	Typical Cost Per Tooth (USD)	Common Use
Amalgam (Silver)	$100–$350	Back teeth where strength matters more than appearance.
Composite Resin	$100–$400	Front teeth and visible areas that need a natural look.
Ceramic (Porcelain)	$500–$1,500+	Inlays, onlays, or large repairs that match tooth shade.
Gold	$500–$1,500+	Back teeth that need long-lasting strength.
Glass Ionomer	$100–$300	Root surfaces, baby teeth, and areas near the gumline.
Temporary Filling	$90–$250	Short-term fix before a crown, root canal, or final work.
Large Indirect Filling	$700–$1,700+	Lab-made inlay or onlay for big cavities and broken cusps.

These numbers describe common ranges from national fee surveys and cost tools, not a fixed menu that every dentist must follow. A clinic in a dense city with high overhead often charges more than a small practice in a smaller town, and each dentist sets a fee schedule that fits that office.

Cavity Filling Cost By Material And Tooth Location

Once you look past the simple question “how much are cavity fillings?”, the next step is matching material and tooth position with your budget and your goals. Different fillings bring different strengths, trade-offs, and price brackets.

Amalgam Fillings

Amalgam fillings combine mercury with metals such as silver, tin, and copper. Dentists have used them for many decades. They handle strong chewing forces, they tolerate moisture during placement, and they usually sit on back teeth where the dark color does not show much.

On cost charts, amalgam sits near the base of the price range. American Dental Association fee surveys and dentist cost guides often place small amalgam fillings around $145 to $190 on average, with larger fillings and hard-to-reach spots adding to that figure. In many insurance plans, amalgam is the reference material for back teeth, so coverage tends to line up with these fees.

Composite (Tooth-Colored) Fillings

Composite fillings use a resin that bonds to tooth structure and blends with enamel. Dentists often pick composite for front teeth and any surface that shows when you smile or talk. Many people like this material because the repair is hard to see in everyday life.

Composite fillings usually cost more than comparable amalgam work. Fee surveys that separate front and back teeth often place a small composite filling on a front tooth near $175 per tooth on average, with higher charges for larger fillings and molars. The higher price reflects both material cost and extra time spent layering and shaping the resin.

Ceramic And Gold Fillings

Ceramic fillings, often made from porcelain, and cast gold fillings sit at the top of the price ladder. These restorations usually involve a lab that makes an inlay, onlay, or partial crown from a mold or scan. That process adds lab fees and at least one extra visit.

CareCredit and other dental finance guides describe ranges from a few hundred dollars up to around $1,700 for a single tooth, depending on size, lab fees, and technique. Dentists may suggest this route when a cavity is wide, the tooth already has cracks, or bite forces are high and extra strength makes sense.

Glass Ionomer And Temporary Fillings

Glass ionomer fillings mix glass and acrylic and can release fluoride over time. Dentists use them near the gumline, on root surfaces, and in baby teeth where chewing forces stay lower. Published ranges often place these fillings in the same general band as basic amalgam or composite, though they may not last as long under heavy chewing.

Temporary fillings hold a space while a tooth waits for a crown, root canal, or other complex work. Because the material and placement are short term, fees tend to land toward the lower end of the filling price spectrum.

Other Things That Change Filling Price

Material is only one piece of the bill. Two people with the same dentist can see very different totals because the tooth, the cavity, and the insurance math do not match.

Size And Depth Of The Cavity

A small spot of decay on one surface is quick to treat and needs little material. A deeper cavity that reaches several surfaces or the biting edge takes more time and more skill. Insurance codes reflect this difference, so larger repairs carry higher fees in both cash and insurance settings.

Front Teeth Versus Molars

Front teeth have a simpler shape and are easier to reach. Molars have grooves and pits, and the dentist has to work farther back in the mouth. Many cost tools and fee surveys show lower fees for small fillings on front teeth and higher fees for fillings on back teeth, where both access and chewing load add work.

Dentist Fees And Local Prices

Every practice writes its own fee schedule based on rent, staff wages, supplies, and local price levels. A filling that costs $180 in one town might cost $280 in another. Tools such as FAIR Health cost estimates use insurance claim data to show common charges and out-of-pocket costs for dental work in your area.

Insurance, Deductibles, And Coinsurance

Most dental plans treat fillings as a basic service and pay a percentage of the allowed fee after you meet the yearly deductible. Coverage levels such as 50%, 70%, or 80% are common. Your share can range from a small copay to most of the bill if the plan caps yearly benefits or if the dentist is outside the network.

Guides from FAIR Health and other consumer groups explain how deductibles, coinsurance, copays, and annual maximums work in dental plans, and why two people with the same plan can still pay different amounts once upgrades and previous treatment enter the picture.

How Insurance And Payment Plans Shape The Bill

Insurance can change the answer to “how much are cavity fillings?” more than almost any other factor. Two patients can have the same tooth treated in the same office and still see very different numbers on the statement because their plan details are not the same.

With Dental Insurance

When a dentist participates in your plan’s network, the plan usually sets a contracted fee for each filling code. The plan then pays a share of that allowed fee, and you pay the rest. Say the contracted fee is $200 and your plan covers 70% of basic services after the deductible. In that case, your share would be $60 plus any remaining deductible.

If you pick a material that the plan treats as an upgrade, such as composite on a back tooth when the plan only covers amalgam there, you may see an extra amount on top of your usual share. Offices often list that upgrade difference clearly on the treatment estimate so you can decide whether the cosmetic benefit is worth the extra money.

Paying Cash Or Using Membership Plans

Many clinics offer a cash discount when you pay in full on the day of service. Some offices also run membership plans where you pay a yearly fee in exchange for lower, fixed prices on fillings, cleanings, and other visits. In that setup, a filling that lists at $250 might drop to $180 or less once the membership rate applies.

Third-party financing, including credit cards and healthcare finance companies, can spread payments over several months. CareCredit publishes ranges that show how total filling cost changes by material, tooth, and number of fillings. Before you sign, read the terms for interest, deferred interest clauses, and late fees so the payment plan does not turn an affordable filling into a long-lasting debt.

Ways To Lower The Cost Of A Cavity Filling

Delaying treatment often turns a simple filling into a larger problem, so the goal is usually to keep the cavity small and the repair simple. A few practical steps can keep the final bill closer to the bottom of the ranges above.

Ask For A Written Treatment Plan

Before the drill turns on, ask the office for a printed or digital plan that lists each code, the fee, and your estimated share. That sheet lets you check how the work lines up with your plan booklet and gives you clear numbers if you want to call the insurer with questions.

Compare Quotes Between Clinics

If you have several dentists near you, you can ask for a second opinion on both treatment and price. When you call another office, ask the front desk to quote a fee range for the same filling code your current dentist suggested. Even a $50 difference per tooth matters when several fillings are on the schedule.

Use Dental Schools Or Public Clinics

Dental schools allow students to treat patients while faculty oversee every step, often at a reduced fee. Local health clinics and non-profit dental centers sometimes run programs for people with lower income. Availability depends on region, so it helps to search by your city or state and ask about current wait times.

Talk With Your Dentist About Material Choices

In some cases you can pick between more than one material for the same cavity. A tooth-colored composite on a back tooth may look nicer, but an amalgam filling might cost less and still protect the tooth well. Your dentist can explain which materials suit the size and location of your cavity and share what each option costs in that office.

Cost-Saving Step	Likely Benefit	Best Match
Check Insurance Coverage Before Treatment	Reduces surprise bills and upgrade charges.	Patients with active dental plans.
Ask About Cash Or Membership Prices	Can trim per-tooth cost by a noticeable amount.	People without insurance or low benefits.
Use In-Network Dentists	Access to contracted lower fees.	Anyone with PPO or HMO dental coverage.
Pick Amalgam For Back Teeth	Often cheaper than composite or ceramic.	Molars that do not show when you smile.
Visit Dental Schools Or Public Clinics	Lower fees in exchange for longer visits.	Patients with flexible schedules.
Address Cavities Early	Helps avoid costly root canals and crowns.	Anyone who attends regular checkups.

When A Filling Might Not Be Enough

Sometimes a tooth hurts or breaks in a way that a simple filling cannot fully handle. Deep decay that reaches the nerve may need root canal treatment followed by a crown. A tooth with large old fillings and cracks may also need more than another filling stacked on top.

Those treatments cost far more than basic fillings, which is why catching decay early protects both your mouth and your budget. Regular exams and X-rays give your dentist a chance to spot small soft spots before they spread, so that “how much are cavity fillings?” stays closer to the lower end of the scale and away from crown-level prices.

You can still adjust many parts of the bill: the material, the clinic, the timing, and how you pay. Clear questions, written estimates, and a dentist who walks through options with you turn the cost of a cavity filling from a mystery into a plan you can handle.
