How Much Does It Cost To Fill A Cavity?
Cavities are one of the most common dental problems in the world. Almost everyone will experience at least one cavity in their lifetime. A cavity is a small hole in your tooth caused by decay. If it is not treated, it can grow larger, cause pain, and eventually lead to infection or tooth loss.
The good news is that filling a cavity is a simple and relatively affordable procedure. But how much does it actually cost? The answer can range from as little as $50 to as much as $600 or more, depending on the type of filling, the size of the cavity, and where you live.
If you have been told you need a cavity filled, you probably want to know what to expect. This guide will walk you through the real costs of filling a cavity. We will look at average prices, explain what affects the cost, compare different types of fillings, and share practical ways to save money. By the end, you should have a clear picture of what to expect and how to plan for your dental care.
What Is A Cavity?
A cavity, also called dental caries, is a permanently damaged area in the hard surface of your tooth. It develops when bacteria in your mouth produce acid that eats away at your tooth enamel. If the decay is not stopped, it can reach deeper layers of the tooth, causing pain and infection.
Cavities start small. In the early stages, you may not even notice them. But as they grow, you may experience:
- Toothache
- Sensitivity to hot or cold
- Visible holes or pits in your teeth
- Brown, black, or white spots on your teeth
- Pain when biting down
The sooner a cavity is treated, the easier and cheaper it is to fix. A small cavity can be filled in one visit. A large cavity may require a root canal and crown, which cost much more.
What Is A Cavity Filling?
A cavity filling is a procedure where your dentist removes the decayed part of your tooth and fills the space with a restorative material. The filling restores the tooth’s shape and function, stops the decay from spreading, and relieves pain.
There are several types of filling materials. Each has its own advantages, disadvantages, and cost.
Types Of Cavity Fillings And Their Costs
Let us look at the most common types of fillings and their typical costs.
1. Amalgam Fillings
Amalgam is a mixture of silver, tin, copper, and mercury. It has been used for over 150 years. It is strong, durable, and relatively inexpensive. However, it is silver in color and can be noticeable. Some people also have concerns about mercury content, though dental amalgam is considered safe by major health organizations.
Average cost: $50 โ $200 per filling
2. Composite Fillings
Composite fillings are made of tooth-colored resin and glass particles. They are popular because they match the natural color of your teeth. They bond well to the tooth structure and require less removal of healthy tooth. However, they are less durable than amalgam and may stain over time.
Average cost: $90 โ $300 per filling
3. Gold Fillings
Gold fillings are made of a gold alloy. They are extremely durable and can last 20 years or more. They are also very expensive and noticeable. They require more than one visit because they are made in a lab.
Average cost: $250 โ $500 per filling
4. Ceramic Fillings
Ceramic fillings are made of porcelain. They are tooth-colored, stain-resistant, and look very natural. They are also more expensive than composite and can be brittle.
Average cost: $300 โ $600 per filling
5. Glass Ionomer Fillings
Glass ionomer fillings are made of acrylic and glass. They release fluoride, which helps prevent further decay. They are often used for children’s teeth, fillings near the gumline, and temporary fillings. They are not as strong as other materials.
Average cost: $75 โ $200 per filling
Comparative Table: Cost Of Cavity Fillings By Type
| Type Of Filling | Average Cost (USD) | Durability | Appearance |
|---|---|---|---|
| Amalgam | $50 โ $200 | 10 โ 15 years | Silver, noticeable |
| Composite | $90 โ $300 | 5 โ 10 years | Tooth-colored, natural |
| Gold | $250 โ $500 | 20+ years | Gold, noticeable |
| Ceramic | $300 โ $600 | 10 โ 15 years | Tooth-colored, natural |
| Glass Ionomer | $75 โ $200 | 5 โ 10 years | Tooth-colored, less natural |
What Affects The Cost Of Filling A Cavity?
Many factors influence the final price. Let us look at the most important ones.
1. Size Of The Cavity
This is a big factor. A small cavity on one surface of a tooth is easier to fill than a large cavity that affects multiple surfaces. The larger the cavity, the more time and material are needed.
- Small cavity (one surface): $50 โ $200
- Medium cavity (two surfaces): $100 โ $300
- Large cavity (three or more surfaces): $200 โ $600+
2. Type Of Filling Material
As mentioned earlier, gold and ceramic fillings are the most expensive. Amalgam and glass ionomer are the cheapest. Composite is in the middle.
3. Location Of The Cavity
Cavities on front teeth are often filled with composite for aesthetic reasons. Cavities on back teeth may be filled with amalgam or composite. Back teeth are harder to reach and need to withstand more chewing force, which can affect the cost.
4. Dentist’s Experience And Reputation
An experienced dentist will charge more than a new practitioner. Cosmetic dentists who place tooth-colored fillings may charge more than general dentists.
5. Geographic Location
Where you live makes a big difference. A filling in New York City or San Francisco will cost more than a filling in a small town. The cost of living, rent, and local demand all affect fees.
6. Additional Procedures
Sometimes a filling requires extra work:
- X-rays: To see the extent of the decay. Cost: $50 โ $200.
- Numbing: Usually included in the filling fee.
- Pulp cap: If the decay is close to the nerve. Cost: $50 โ $200.
- Root canal: If the decay has reached the nerve. Cost: $500 โ $1,500.
- Crown: If the tooth is too damaged for a filling. Cost: $500 โ $2,000.
These add significantly to the overall bill.
7. Insurance Coverage
If you have dental insurance, your out-of-pocket cost may be much lower. If you do not, you pay the full fee. We will cover insurance in more detail below.
8. Time Of Year
Some offices offer promotions in January or during Dental Health Month. Others raise prices at the start of the year. It never hurts to ask about current specials.

Does Insurance Cover Filling A Cavity?
In most cases, dental insurance covers a portion of the cost of cavity fillings. Fillings are considered restorative, not cosmetic, so they are usually covered. However, coverage varies.
Here is what you need to know:
- Percentage covered: Many plans cover 50% to 80% of the cost after you meet your deductible.
- Annual maximum: Most plans have an annual maximum, such as $1,000 or $2,000. Once you reach that limit, you pay the full cost.
- Deductible: You may need to pay a deductible before insurance kicks in.
- In-network providers: You may get better coverage if you see a dentist in your insurance network.
- Type of filling: Some plans cover amalgam fillings but not composite. If you want composite, you may pay the difference.
Always call your insurance company before treatment. Ask specific questions:
- Is the filling covered?
- What percentage is covered?
- Is there a deductible?
- Are there any waiting periods?
How To Save Money On Cavity Fillings
Here are some practical ways to reduce the cost without compromising quality.
1. Use Insurance
If you have dental insurance, use it. Even a small contribution helps.
2. Flexible Spending Accounts (FSAs) And Health Savings Accounts (HSAs)
If you have an FSA or HSA, you can use pre-tax dollars to pay for fillings. This can save you 20% to 30% depending on your tax bracket.
3. Go To A Dental School
Dental schools offer lower-cost fillings performed by supervised students. The trade-off is that appointments take longer.
4. Compare Clinics
Prices vary. Call a few clinics in your area and compare. Do not just choose the cheapest option. Check reviews and ask about the dentist’s experience.
5. Practice Good Oral Hygiene
Brushing twice a day, flossing daily, and visiting your dentist regularly can prevent cavities. Prevention is always cheaper than treatment.
6. Treat Cavities Early
Small cavities are cheaper to fill than large ones. If you wait, the decay may reach the nerve, requiring a root canal and crown, which cost much more.
7. Ask About Discounts
Some offices offer discounts for paying in full upfront, for multiple family members, or for referrals. It never hurts to ask.
8. Negotiate
Dentistry is a business. Sometimes you can negotiate the price, especially if you are paying cash. Be polite and respectful, but do ask.
The Process Of Filling A Cavity
Understanding the process helps you see where your money goes.
Step 1: Examination
Your dentist examines your teeth, takes X-rays if needed, and identifies the cavity.
Step 2: Numbing
The dentist numbs the area around the tooth with local anesthesia. This ensures you do not feel pain during the procedure.
Step 3: Removal Of Decay
The dentist uses a drill or laser to remove the decayed part of the tooth. The area is cleaned.
Step 4: Filling Placement
The filling material is placed into the cavity. For composite fillings, the material is applied in layers and hardened with a special light. For amalgam, the material is packed into the cavity. For gold or ceramic, impressions are taken and the filling is made in a lab.
Step 5: Shaping And Polishing
The dentist shapes the filling to match your bite and polishes it for a smooth finish.
Step 6: Follow-Up
You may have a follow-up appointment to check the filling and ensure your bite is comfortable.
How Long Do Cavity Fillings Last?
The lifespan of a filling depends on the material, your oral habits, and the location of the filling.
| Type Of Filling | Average Lifespan |
|---|---|
| Amalgam | 10 โ 15 years |
| Composite | 5 โ 10 years |
| Gold | 20+ years |
| Ceramic | 10 โ 15 years |
| Glass Ionomer | 5 โ 10 years |
To extend the life of your filling:
- Practice good oral hygiene
- Avoid biting on hard objects
- Wear a mouthguard if you grind your teeth
- Visit your dentist regularly
