Dental fillings for cavities usually cost about $100 to $500 per tooth, depending on material, tooth location, and whether you have dental insurance.
You finally asked your dentist what it will cost to fix that tiny dark spot, and the answer was, “It depends.” That can feel vague when you just need a clear sense of what a filling will do to your budget.
This guide shares realistic price ranges for common filling materials, why quotes differ from clinic to clinic, and how to plan for the bill with or without insurance.
How Much Are Fillings For Cavities? Average Price Ranges
Across many clinics, a simple filling for one tooth tends to start around $100 on the low end and can reach $400 or more for tooth-colored materials in a back molar.
Metal amalgam fillings often fall near the lower part of that range, while resin fillings that match tooth shade usually sit higher because the material costs more and the procedure takes extra chair time.
Gold and ceramic inlays or onlays, which are custom pieces made in a lab, sit in their own price bracket and can reach several hundred dollars or even more than $1,000 for a single tooth.
These figures reflect typical prices in the United States without special discounts, and they already assume a small to medium cavity with one or two tooth surfaces involved.
Typical Cavity Filling Cost By Material
The table below groups common filling materials and the ranges often quoted for a single tooth in general dental practices.
| Filling Material | Typical Cost Without Insurance* | Typical Cost With Insurance* |
|---|---|---|
| Silver amalgam | $100–$250 per tooth | $0–$100 per tooth |
| Tooth-colored composite (small) | $150–$400 per tooth | $50–$200 per tooth |
| Composite (large back tooth) | $200–$500 per tooth | $80–$250 per tooth |
| Glass ionomer | $150–$350 per tooth | $50–$200 per tooth |
| Porcelain or ceramic inlay | $500–$1,500 per tooth | $200–$800 per tooth |
| Gold inlay or onlay | $600–$2,000 per tooth | $250–$900 per tooth |
| Temporary filling | $75–$200 per tooth | Coverage varies by plan |
*These ranges are broad ballpark figures. Insurance examples assume a plan that treats fillings as a basic service at roughly 50% coverage after any deductible. Your own policy may use very different numbers.
Insurance plans that treat fillings as a basic service may pay around half of the dentist’s fee, yet the same procedure can leave two patients with noticeably different final bills.
Fillings For Cavities Cost Breakdown By Material
Material choice is usually the first reason one person pays much more than another for what sounds like the same cavity filling.
Silver amalgam has a long track record and tends to cost less because clinics have used it for decades and the procedure is fast for most dentists.
Composite fillings blend in with natural tooth shade, which keeps smiles looking uniform, yet they are more technique-sensitive and can require extra layers, curing steps, and finishing work.
Ceramic and gold restorations are often suggested when a large part of the tooth has broken down or when a person wants a restoration that resists heavy chewing for many years.
From a cost point of view, those lab-made options behave more like small crowns than like simple fillings, so the line on your estimate reflects extra lab fees and extra chair time.
Public resources from national dental groups explain that
fillings repair small holes created by decay, and that dentists match the material to cavity size, tooth location, and your general health.
In the American Dental Association’s
MouthHealthy dental filling options guide, material choice is tied to cavity size, tooth location, and cosmetic goals, which also influence cost.
That simple idea explains why a tiny surface spot in a front tooth can cost far less than a wide cavity that wraps across the chewing surface of a molar.
Other Factors That Change Filling Prices
Two patients can sit in the same waiting room and still walk away with different charges because the details of their teeth and their treatment plans are not the same.
Tooth Location And Cavity Size
Front teeth usually cost less to restore than molars because they are easier to reach and often have smaller biting surfaces.
Molars and premolars take longer to numb, prepare, and shape, and the chewing pressure they handle may push your dentist to suggest a stronger material or a more involved restoration.
Dentists also bill based on how many surfaces of the tooth need work, so a single small spot on one surface costs less than a large cavity that touches three or four surfaces.
New Patient Visits, X Rays, And Exams
If you have not seen a dentist in a while, the cost of a filling often sits beside charges for an exam, X rays, and a separate cleaning visit.
Dentist Experience And Clinic Overheads
A dentist in a busy city center with higher rent and extra cosmetic training may charge more per filling than a clinic in a smaller town, even when both use the same filling code.
You are paying for materials, staff time, sterilization, equipment, and the dentist’s skill, so the same filling code in two offices can carry noticeably different price tags.
Insurance Plans, Copays, And Deductibles
Many dental plans group fillings under basic restorative care and cover a certain percentage once you meet your deductible.
The allowed fee may be lower than the dentist’s standard fee, and the difference can fall on you, which is why an estimate that includes both plan payments and your share matters so much.
Some plans also set a yearly maximum, so if you have had several treatments already, you may pay the full cost of new fillings even though you still hold an active policy.
Discount Plans And Payment Options
People without traditional insurance may join discount plans, sign up for clinic membership programs, or use payment plans that spread costs over several months.
Membership plans might offer a set number of exams and cleanings plus a discount on fillings, while third-party financing spreads the cost out but may add interest or fees.
If money is tight, ask the front desk about every option before you agree to treatment so you can pick a schedule and payment method that fits your budget.
How Dental Insurance Changes The Cost Of A Cavity Filling
With dental insurance, the headline cost on the clinic fee sheet is rarely the number you pay after the claim is processed.
Many plans cover preventive visits at one hundred percent, basic restorative work like simple fillings at a higher percentage after a deductible, and major work such as crowns at a lower rate.
Because fillings sit in the middle band, they often give solid value when you still have yearly benefits left, especially if you catch decay early while the cavity is small.
Keep in mind that insurance companies usually set their own allowed amounts, so a plan may pay its percentage based on a lower figure than the clinic charges, leaving you to pay the difference plus any deductible and copay.
Before treatment, ask the office to send a pre-treatment estimate so your insurer can reply with a breakdown of what they expect to pay and what they expect you to pay.
That simple sheet gives you a clearer view of how many fillings you can schedule this year without blowing through your yearly maximum.
Seeing those numbers written out gives many people the confidence to ask questions and choose the option that suits them right now.
How Region And Currency Influence Cavity Filling Prices
Average filling fees change with local wages, rent, and exchange rates, so price bands in one country rarely match another country exactly.
Ask clinics near you, including teaching hospitals and public programs when they exist, for written fee lists so you can compare local prices instead of relying on overseas examples.
Budgeting For Multiple Cavity Fillings Over A Year
If your dentist has flagged several small cavities, the total cost can feel intimidating even though each filling on its own sits in a moderate price band.
One simple approach is to map fillings against your yearly insurance maximum or personal savings, tackling the teeth that bother you most or that risk turning into root canal cases first.
Then you can schedule the rest across the year or into the next year so more of the fees fall under fresh insurance benefits or new savings cycles.
Common Filling Cost Factors And What You Can Do
Use this quick reference table to spot the levers that move your price quote up or down and the questions that help you control the final bill.
| Cost Factor | Effect On Price | What You Can Do |
|---|---|---|
| Filling material | Tooth-colored and lab-made options cost more. | Ask which safe materials fit your tooth and budget best. |
| Cavity size | Larger cavities take more time and material. | Ask whether early treatment can keep later fillings smaller. |
| Tooth position | Molars are harder to reach and restore. | Ask if a similar case in a premolar would cost less. |
| Number of surfaces | Each extra surface adds to the fee. | Ask your dentist to show you exactly which surfaces need work. |
| Clinic location | City center offices often charge higher fees. | Ask for quotes from a few clinics within a distance you can travel. |
| Insurance coverage | Plan rules cap what the insurer pays. | Ask for a pre-treatment estimate that lists your share clearly. |
| Financing and discounts | Payment plans can add interest or fees. | Ask whether a membership plan or upfront discount fits you better. |
Making Smart Choices About Filling Costs
Money questions should not push you to delay needed care until a small cavity turns into a painful infection that needs root canal treatment or extraction.
If a quote worries you, talk with your dentist about other safe materials, phased treatment, or referral to a clinic that matches your budget better.
Trusted health organizations explain that early treatment of decay with a filling protects tooth structure and reduces the chance that you will need more complex work later.
That is why it helps to treat cost as one part of the decision, balanced with comfort, chewing strength, and long term tooth survival.
Once you understand the price ranges and the levers that affect them, you can agree to a filling plan that protects your teeth and fits your budget.
