The answer varies widely, from $50 to $500 or more, depending on the material, the size of the cavity, and where you live.
This guide will break down the typical costs of dental fillings. We’ll cover the different types of fillings, what affects the price, insurance coverage, and practical tips to save money. By the end, you’ll know exactly what to expect—and how to keep your smile healthy without breaking the bank.
What Is a Dental Filling?
A dental filling is a material used to repair a tooth damaged by decay or trauma. Your dentist removes the decayed portion, cleans the area, and fills the cavity with a restorative material. The goal is to stop decay from spreading and restore the tooth’s function.
Fillings are needed for:
- Cavities (tooth decay)
- Cracked or broken teeth
- Worn-down teeth from grinding
- Replacing old, failing fillings
There are several types of filling materials. Each has its own cost, durability, and appearance.
Average Cost of a Dental Filling
Let’s get to the numbers. Here’s what you can expect to pay.
| Type of Filling | Average Cost (US) | Average Cost (UK) | Average Cost (Canada) |
|---|---|---|---|
| Amalgam (Silver) | $50 – $150 | £30 – £80 | CAD $60 – $180 |
| Composite (White) | $90 – $250 | £40 – £120 | CAD $100 – $300 |
| Glass Ionomer | $70 – $200 | £35 – £100 | CAD $80 – $220 |
| Ceramic | $150 – $400 | £100 – £250 | CAD $180 – $450 |

| Temporary Filling | $20 – $50 | £15 – £40 | CAD $25 – $60 |
Note: These prices are per tooth. Multiple fillings cost more. Prices vary by region and clinic.
Types of Dental Fillings and Their Costs
Not all fillings are the same. The material affects the price, durability, and appearance.
Amalgam Fillings
Amalgam is a mix of silver, tin, copper, and mercury. It’s strong and cheap. But it’s silver-colored, so it’s visible. Some people worry about mercury, but studies show it’s safe.
Cost: $50 – $150
Pros: Durable, cheap, long-lasting (10-15 years).
Cons: Visible, contains mercury, can expand over time.
Composite Fillings
Composite is a tooth-colored resin. It blends in with your natural teeth. It’s the most popular choice today.
Cost: $90 – $250
Pros: Natural look, bonds to tooth, less drilling.
Cons: More expensive than amalgam, can stain over time, lasts 5-10 years.
Glass Ionomer Fillings
These are made of acrylic and glass. They release fluoride, which helps prevent decay. They’re often used for children or root surfaces.
Cost: $70 – $200
Pros: Releases fluoride, good for kids, less sensitive.
Cons: Weaker than composite, wears down faster.
Ceramic Fillings
Ceramic fillings are made of porcelain. They’re tooth-colored and very durable. They’re often used for larger cavities.
Cost: $150 – $400
Pros: Natural look, durable, resistant to staining.
Cons: Expensive, can wear down opposing teeth.
Inlays and Onlays
These are custom-made fillings created in a lab. They’re used for larger cavities. Inlays fit inside the tooth; onlays cover one or more cusps.
Cost: $250 – $600
Pros: Very durable, custom-fit, natural look.
Cons: Expensive, requires two visits.
Temporary Fillings
Used as a short-term fix before permanent treatment. They’re not meant to last.
Cost: $20 – $50
Pros: Quick, cheap, relieves pain.
Cons: Temporary, can fall out, not a long-term solution.
What Affects the Cost of a Dental Filling?
Several factors influence the price. Understanding them helps you budget and compare quotes.
Cavity Size and Complexity
A small cavity is quick and easy. A large cavity takes longer, uses more material, and may need additional work. The bigger the problem, the higher the cost.
Number of Surfaces
Dentists charge by the number of tooth surfaces affected. A one-surface filling costs less than a three-surface filling. A filling on the front of a tooth may cost more because it’s more visible and requires careful shaping.
Dentist’s Experience and Reputation
A highly experienced dentist with a great reputation charges more. You’re paying for skill, precision, and a lower risk of complications. A newly qualified dentist may charge less.
Geographic Location
Big cities have higher overhead costs. Rural areas are cheaper.
| Location | Average Composite Filling Cost |
|---|---|
| New York City | $150 – $350 |
| Small town, Midwest | $90 – $180 |
| London, UK | £60 – £120 |
| Rural Canada | CAD $100 – $200 |
Type of Clinic
- Private clinic: Higher fees.
- Dental school: 30% – 50% off.
- Community health center: Sliding scale fees.
- Insurance: May cover part of the cost.
Additional Procedures
Sometimes a filling isn’t enough. You might need:
- Root canal: $400 – $1,200
- Crown: $500 – $1,500
- Extraction: $150 – $500
These add significantly to the total.
Emergency vs. Scheduled
Emergency appointments cost more. If you’re in pain and need immediate care, expect to pay a premium.
Does Insurance Cover Dental Fillings?
It depends on your plan. Here’s what you need to know.
Dental Insurance
Most dental insurance plans cover fillings. But there are limits.
- Coverage percentage: 50% to 80% for fillings.
- Annual maximum: $1,000 to $2,000.
- Waiting periods: Some plans require 6 to 12 months of enrollment.
- Exclusions: Some plans don’t cover composite fillings on back teeth.
Tip: Call your insurance company and ask:
- Is the filling covered?
- What’s my out-of-pocket cost?
- Do I need pre-authorization?
- Is the dentist in-network?
Medicaid
Medicaid covers medically necessary fillings for eligible adults and children. Coverage varies by state.
Medicare
Original Medicare does not cover dental fillings. Medicare Advantage plans may offer dental coverage.
NHS (UK)
NHS dental care covers fillings. In 2025, the Band 2 charge is £70.20. If you’re exempt from NHS charges, it’s free.
Hidden Costs to Watch Out For
The quoted price isn’t always the final price. Watch out for these extras.
X-Rays
Most dentists take an X-ray before treatment. It costs $15 – $50. Some clinics include it; others charge separately.
Anesthesia
Local anesthesia is usually included. But if you need sedation, that’s $100 – $300 extra.
Temporary Filling
If you need a temporary filling before a permanent one, that’s $20 – $50.
Follow-Up Visits
Some clinics charge for follow-up visits. Ask if they’re included.
Replacement Fillings
Fillings don’t last forever. Composite lasts 5-10 years; amalgam lasts 10-15 years. When they fail, you’ll pay again.
Missed Appointment Fees
Some clinics charge $50 – $100 if you miss an appointment without notice.
Important: Always ask for a written treatment plan with a full cost breakdown before you start.
How to Save Money on Dental Fillings

Prices vary widely. Call several dentists and compare. Don’t just look at the price—look at what’s included.
Visit a Dental School

Clinics in residential areas often charge less than those in city centers or tourist zones.

Some clinics offer discounts for new patients, seniors, or multiple fillings. Ask.
