How Much Does It Cost to Fix a Cavity?

For a conventional cavity filling in the U.S., current uninsured prices commonly run about $110 to $530 per tooth. Current Delta Dental consumer guidance lists amalgam fillings at about $110 to $455 and composite fillings at about $145 to $480 for front teeth or $165 to $530 for back teeth, depending largely on the number of tooth surfaces being restored.

Your actual cavity filling cost can be lower or higher based on the material, tooth, number of surfaces involved, local dental fees, and insurance network. Gold and porcelain restorations can cost substantially more because they may be indirect restorations made outside the mouth rather than simple direct fillings.

Not every early area of tooth decay automatically needs drilling and filling. Very early enamel decay may sometimes be managed with fluoride and other preventive treatment, while deeper or structurally damaged teeth may need a filling, crown, root canal, or another treatment. Your dentist must examine the tooth before giving you an exact treatment plan.

Quick Answer

Here is the practical bottom line on cavity filling costs in the U.S.:

• Amalgam fillings: about $110 to $455 without insurance, depending on the number of surfaces restored.
• Composite fillings: about $145 to $480 for front teeth and $165 to $530 for back teeth without insurance.
• Dental insurance: many plans cover about 50% to 80% of basic procedures such as fillings after applicable deductibles, but your plan can differ.
• Local anesthesia: it is generally included in the normal filling fee rather than billed as a separate $50 to $200 charge.
• X-rays: diagnostic imaging may add to the bill when clinically necessary, although some insurance plans cover routine diagnostic X-rays.

Use national ranges only for budgeting. The most useful number is the written estimate for your specific tooth, material, number of surfaces and insurance status.

What Affects the Cost of Fixing a Cavity?

Dental filling prices are not based on the word “cavity” alone. A dentist usually considers how much tooth structure is affected, where the decay is located and what restoration is appropriate.

Number of Tooth Surfaces

One of the biggest price factors is how many surfaces of the tooth need to be restored. A small one-surface filling generally costs less than a two-, three-, or multi-surface restoration because more material and chair time may be required.

Ask your dentist how many surfaces are included in the treatment estimate. This is often more useful than simply asking whether the cavity is “small” or “large.”

Depth and Extent of Decay

Very early decay confined to enamel may sometimes be treated without a traditional filling. Once tooth structure is lost and a cavity has formed, restorative treatment is more likely to be needed. If decay reaches the pulp or leaves too little sound tooth structure for a normal filling, a dentist may recommend a root canal, crown, or another procedure instead.

Filling Material

Amalgam is generally less expensive than tooth-colored composite. Gold and porcelain restorations can cost considerably more, particularly when they are fabricated as an inlay or onlay outside the mouth.

Tooth Location and Local Market

Back teeth can cost more to restore than front teeth, particularly with composite material or when several surfaces are involved. Prices also vary by ZIP code, practice overhead, local labor costs and the dentist’s contracted rates with insurance companies.

Insurance Network and Benefits

An in-network dentist has negotiated fees with your dental plan. Going out of network may increase the amount you pay. Your deductible, coinsurance, annual maximum and the type of filling your plan recognizes can also change your final out-of-pocket cost.

Cost Factor	How It Can Affect the Bill
Number of surfaces	More tooth surfaces generally mean a more involved and higher-priced restoration.
Depth of decay	Advanced decay may require treatment beyond a standard filling.
Material	Amalgam is generally cheaper than composite; indirect gold or porcelain restorations cost more.
Tooth location	Back-tooth composite restorations can cost more than comparable front-tooth fillings.
Location and provider	Local fees, practice setting and contracted insurance rates differ by market.
Insurance	Deductibles, coinsurance, annual maximums and network status affect your share.

 

Types of Fillings and Typical Costs

The two most common conventional filling choices are amalgam and tooth-colored composite. Gold, ceramic and some other materials may be used as indirect restorations depending on the tooth and extent of damage.

Amalgam Fillings

Amalgam fillings are metal restorations containing mercury combined with silver, copper, tin and other components. They are durable and are commonly associated with back-tooth restorations. Current Delta Dental guidance places uninsured amalgam fillings at roughly $110 to $455, depending mainly on the number of surfaces being restored.

The FDA recommends that certain higher-risk groups avoid new amalgam fillings when possible and appropriate. These groups include people who are pregnant or planning pregnancy, nursing mothers, young children, people with neurological impairment or kidney dysfunction, and people with known sensitivity to mercury or other amalgam components. The FDA does not recommend automatically removing an existing amalgam filling that is in good condition unless medically necessary. See the FDA dental amalgam guidance and discuss the best material for your situation with your dentist.

Typical current uninsured range: about $110 to $455 per tooth, depending on surfaces.

Composite Fillings

Composite fillings use tooth-colored resin material that blends with natural teeth. Composite is widely used on both front and back teeth and bonds directly to the prepared tooth.

Current Delta Dental guidance lists uninsured composite fillings at about $145 to $480 for front teeth and $165 to $530 for back teeth, with the number of restored surfaces being a major reason for the spread.

Gold Fillings and Inlays

Gold restorations are durable but less commonly selected than tooth-colored composite. Some gold restorations are indirect inlays or onlays made outside the mouth, so they may involve laboratory work and more than one appointment.

Current CareCredit national pricing research lists gold fillings at an average of about $466, with a reported range of roughly $361 to $817. Your quote can differ substantially by restoration design and location.

Ceramic Fillings, Inlays and Onlays

Ceramic restorations are tooth-colored and stain resistant. Many ceramic restorations are indirect inlays or onlays rather than ordinary direct fillings, which helps explain their higher price.

Current CareCredit pricing research lists porcelain inlays and onlays at an average of about $976, with a reported national range of approximately $755 to $1,774.

Glass Ionomer Fillings

Glass ionomer is another restorative material used in selected situations. It releases fluoride and may be useful where the dentist considers its properties appropriate, but it is not the strongest choice for every chewing surface.

Current CareCredit consumer pricing information places glass-ionomer fillings at roughly $75 to $200. Suitability matters more than simply choosing the cheapest material.

Restoration	Type	Typical Current Price Reference	Key Point
Amalgam	Direct filling	$110 – $455	Usually among the lower-cost conventional choices.
Composite	Direct filling	$145 – $530	Tooth-colored; cost varies by tooth and surfaces.
Glass ionomer	Direct filling	$75 – $200	Used selectively; not ideal for every load-bearing restoration.
Gold	Direct or indirect restoration	$361 – $817	Durable but more expensive and less commonly selected.
Porcelain / ceramic	Often an indirect inlay/onlay	$755 – $1,774	Higher price partly reflects fabrication and placement method.

Price note: Amalgam and composite ranges above use current Delta Dental consumer guidance. Gold, porcelain and glass-ionomer figures use current CareCredit consumer pricing references; CareCredit states that its national dental-cost research was collected in the 50 states and Washington, D.C., during 2023–2024. These figures are budgeting references, not guaranteed 2026 quotes.

How Much Does Location Change the Price?

Your ZIP code can change the price, but there is no reliable universal table saying every urban filling costs one amount and every rural filling costs another. Local wages, office overhead, insurance contracts and competition vary from market to market.

Urban Vs Rural

A city practice may have higher overhead, but a rural office is not automatically cheaper. The more reliable approach is to compare actual local fees for the same procedure, material and number of tooth surfaces.

If you have insurance, start with the plan’s online cost estimator or member-services department. If you are paying cash, ask two or three offices for the fee for the same proposed treatment after you have a diagnosis.

How to Compare Local Filling Quotes

Make sure each quote is based on the same treatment. Ask for:

• The tooth number.
• The number of surfaces being restored.
• The filling or restoration material.
• Whether the exam and X-rays are separate charges.
• Whether local anesthesia is included.
• The insurance allowed amount, if applicable.
• Your estimated final patient responsibility.

A $180 quote and a $350 quote may not represent the same treatment if one covers a one-surface filling and the other covers a larger multi-surface restoration plus diagnostic services.

How Can You Get an Exact Cavity-Filling Quote?

The most accurate estimate comes after the dentist identifies the tooth and treatment. Ask for a written treatment plan instead of relying only on a national average.

Ask for This	Why It Matters
Tooth number	Confirms exactly which tooth is being treated.
Number of surfaces	A major driver of the filling fee.
Material	Composite, amalgam and indirect restorations have different fees.
Exam and X-ray charges	Shows whether diagnostic costs are separate.
Anesthesia	Local anesthesia is generally included in a standard filling fee, while sedation may be separate.
Insurance allowed amount	Shows the contracted price your plan uses when you stay in network.
Estimated patient share	Combines deductible, coinsurance and other plan rules into the amount you expect to pay.

If you are uninsured or choose to self-pay, federal CMS guidance says you can generally request a Good Faith Estimate of expected charges. Qualifying providers generally must give one when self-pay care is scheduled sufficiently in advance or when you request an estimate. Keep the written estimate so you can compare it with the final bill.

Insurance Coverage

Dental insurance can reduce what you pay, but there is no single coverage percentage that applies to every policy.

Dental Insurance Plans

Current Delta Dental guidance says dental plans typically cover about 50% to 80% of basic procedures such as fillings. Your actual benefit depends on your plan, deductible, network, annual maximum and filling material.

Check these items before treatment:

• Deductible: What you must pay before applicable benefits begin.
• Coinsurance: The percentage of the allowed cost you pay after the deductible.
• Annual maximum: The maximum amount the dental plan will pay during the benefit year.
• Network status: In-network dentists generally use negotiated plan fees.
• Material limitations: Some policies may calculate benefits based on a less expensive restoration even when another material is selected.
• Waiting period: Some plans limit benefits for certain services during an initial period.

Out-of-pocket Costs

Your out-of-pocket amount is not simply the dentist’s retail fee minus “80%.” The insurer may first apply its contracted allowed amount, then your deductible, coinsurance, annual maximum and other plan rules.

Plan Term	What It Changes
Allowed amount	The negotiated or recognized price used by the plan for the covered service.
Deductible	The amount you may need to pay before applicable benefits begin.
Coinsurance	Your percentage of the covered allowed amount.
Annual maximum	Limits how much the plan pays during the year.
Out-of-network billing	Can leave you responsible for more than an in-network visit.

Ask the dental office to submit a pre-treatment estimate to your insurer for a larger restoration if your plan offers that option.

Are X-Rays and Anesthesia Extra?

X-rays

Dental X-rays help a dentist see decay and other conditions that may not be visible during a normal examination. The ADA’s 2026 recommendations emphasize that X-rays should be ordered when clinically necessary based on a person’s oral health, age, disease risk, symptoms and available prior images rather than on a one-size-fits-all schedule.

Current CareCredit national pricing research lists the following uninsured planning ranges:

Type of X-ray	Typical National Range
Bitewing	$52 – $120
Full-Mouth Series	$175 – $428

Insurance may cover some diagnostic X-rays, subject to plan frequency limits and other rules. If you recently changed dentists, ask whether usable previous images can be transferred before new ones are taken.

Anesthesia

Local anesthesia is generally included in the standard filling price. Current Delta Dental guidance specifically notes that the filling price generally includes the material, local anesthesia and the dentist’s time.

Sedation is different from ordinary local numbing. If sedation is needed because of the procedure, anxiety or another clinical reason, ask whether it is separately billed and what type of sedation is being proposed.

Follow-up and Bite Adjustments

A separate paid follow-up is not automatically required after every uncomplicated filling. Contact the dental office if your bite feels high after the numbness wears off or if you have persistent or worsening pain, swelling, or another concern. The office can tell you whether an adjustment or examination is needed and whether any fee applies.

Cost-saving Tips

Lowering the bill should mean finding an appropriate lower-cost provider or benefit, not postponing a needed restoration until the tooth requires more extensive treatment.

Dental Schools

Some dental-school clinics provide patient care through students working under faculty supervision, and their fees can be lower than private-practice fees. Prices, eligibility and appointment availability vary by school, so request the clinic’s actual fee schedule rather than assuming a fixed percentage discount.

Community Health Centers

HRSA-funded health centers provide medical and dental care to patients with or without insurance, and qualifying health centers adjust fees based on income and family size. Availability of restorative dental services varies by site, so confirm that the local clinic provides fillings before scheduling.

Discount Plans

A dental discount plan is not the same as dental insurance. Participating dentists agree to specified discounted fees, while the patient usually pays the discounted charge directly. Compare the membership fee with the actual discount on the treatment you need.

Government Programs

Medicaid and CHIP can help eligible patients obtain dental care. Federal Medicaid guidance states that states must provide dental benefits to children enrolled in Medicaid and CHIP, while adult Medicaid dental benefits vary by state. See Medicaid dental coverage for current program information.

1. Check your state’s eligibility and dental benefits.
2. Confirm that the dentist accepts your Medicaid or CHIP plan.
3. Ask what restorative services and patient charges apply before treatment.

Ask for a Written Self-pay Estimate

If you are uninsured or are not using insurance, ask for a written Good Faith Estimate before scheduled treatment. A written estimate also makes it easier to compare offices using the same treatment details.

Does Every Cavity Need a Filling?

No. “Tooth decay” covers a range from very early mineral loss in enamel to a physical cavity that has destroyed tooth structure. The treatment depends on how far the disease has progressed.

Early enamel lesions may sometimes be managed with fluoride, improved home care, dietary changes and professional monitoring. Once there is a cavitated lesion or enough structural loss, a dentist may recommend a filling. Extensive decay can require a larger restoration, crown, root canal treatment or extraction depending on whether the tooth can be predictably restored.

This is why an online price range cannot tell you which procedure you need. A dentist has to diagnose the tooth first.

How to Prevent Future Cavities

Preventive care can reduce your risk of new decay and help dentists identify problems before they become larger restorations.

Regular Dental Visits

See your dentist at the recall interval recommended for your individual cavity and gum-disease risk. The ADA notes that there is no single optimal recall interval for every patient; frequency should be tailored to individual need.

Proper Oral Hygiene

The ADA recommends brushing twice a day for two minutes with fluoride toothpaste and cleaning between your teeth daily. Mouthrinse can be useful for some people, but it is not a replacement for brushing and interdental cleaning.

Preventive Measure	Benefit
Brush twice daily with fluoride toothpaste	Helps prevent tooth decay and remove plaque.
Clean between teeth daily	Removes plaque where a toothbrush cannot reach effectively.
Risk-based dental visits	Allows professional examination and preventive treatment at an appropriate interval.
Limit frequent sugary snacks and drinks	Reduces repeated acid attacks on tooth enamel.

Food frequency matters as well as total sugar. Frequent snacking can repeatedly expose teeth to acids produced by oral bacteria. Water, balanced meals and fewer sugar-containing snacks between meals can support cavity prevention.

• Brush twice daily for two minutes with fluoride toothpaste.
• Clean between teeth once daily with floss or another appropriate interdental cleaner.
• Limit frequent sugary snacks and drinks.
• Drink water regularly.
• Follow the dental recall schedule recommended for your individual risk.

What Happens If You Delay Cavity Treatment?

A cavity can become more difficult and expensive to restore as additional tooth structure is destroyed. Waiting does not guarantee that you will need a root canal, but deeper decay increases the chance that a simple filling will no longer be enough.

Potential Cost Increase

A conventional amalgam or composite filling may fall roughly within the $110–$530 planning range discussed above. Current CareCredit consumer pricing data place root-canal treatment at roughly $500 to $1,800 overall, while its national dental-cost summary lists crowns at roughly $697 to $1,399. The actual fee depends on the tooth, provider, crown material and local market.

A tooth with severe decay may need both root-canal treatment and a crown, meaning the procedures should not be treated as interchangeable prices.

Treatment	Current Planning Reference
Conventional amalgam/composite filling	About $110 – $530
Root canal	About $500 – $1,800
Dental crown	About $697 – $1,399

Potential Complications

Untreated tooth decay can progress into deeper tooth structures and may eventually cause pain, infection or loss of the tooth. Contact a dentist promptly if you develop significant dental pain, swelling or other worsening symptoms.

Frequently Asked Questions

How Much Does It Cost to Fix a Cavity Without Insurance?

For a conventional filling, current U.S. consumer guidance places uninsured amalgam fillings at about $110 to $455 and composite fillings at about $145 to $530, depending on the tooth and number of surfaces involved. Indirect gold or porcelain restorations can cost substantially more.

What Factors Affect Cavity Filling Cost?

The biggest factors include the number of tooth surfaces being restored, filling material, tooth location, local dental fees and insurance network. Advanced decay may also require treatment beyond a standard filling.

Are Cavity Fillings Covered By Insurance?

Many dental plans cover fillings as a basic service. Current Delta Dental guidance says plans typically cover about 50% to 80% of basic procedures such as fillings, but deductibles, annual maximums, network rules and material limitations can change your actual benefit.

How Long Does A Cavity Filling Take?

A single uncomplicated filling commonly takes about 30 minutes to one hour. The appointment can take longer when several teeth are being treated, the restoration is larger or sedation or another procedure is required.

Does Every Cavity Need a Filling?

No. Very early enamel decay may sometimes be treated with preventive measures such as fluoride and monitored by a dentist. Once tooth structure has been lost and a cavity has formed, a filling or another restoration is more likely to be needed.

Are X-Rays and Local Anesthesia Included in the Filling Price?

Local anesthesia is generally included in the normal filling fee. X-rays and examinations may be separate charges, depending on the office and insurance plan. Current national consumer pricing data place bitewing X-rays at roughly $52 to $120 and a full-mouth series at about $175 to $428.

How Can I Get the Most Accurate Filling Price?

Ask for a written treatment estimate showing the tooth number, number of surfaces, material, exam or X-ray charges, insurance allowed amount and your expected patient share. If you are uninsured or self-pay, ask whether you are entitled to a federal Good Faith Estimate before the scheduled service.

Sources and Methodology

This guide was substantively reviewed on September 7, 2026. The direct amalgam and composite filling ranges and typical insurance coverage were cross-checked against current Delta Dental consumer guidance. Gold, porcelain, glass-ionomer, X-ray, root-canal and crown planning figures were cross-checked against current CareCredit consumer cost references, which state that their national dental-cost research was collected during 2023–2024.

Clinical statements about dental amalgam were checked against the U.S. Food and Drug Administration. Prevention and dental X-ray guidance were checked against current American Dental Association resources, including its 2026 X-ray recommendations. Medicaid and CHIP statements were checked against federal Medicaid guidance. Self-pay Good Faith Estimate guidance was checked against current CMS consumer guidance, and community-health-center fee information was checked against HRSA program guidance.

These prices are national budgeting references rather than quotes. Your dentist’s diagnosis, treatment code, number of surfaces, local fees and insurance benefits determine the actual amount you pay.

Conclusion

For a standard cavity filling in the U.S., budget roughly $110 to $530 without insurance for many amalgam and composite restorations, while indirect gold or porcelain work can cost more. The number of tooth surfaces, material, tooth location and insurance benefits are more useful for predicting your bill than a single national average.

Before treatment, ask for a written estimate that identifies the tooth, number of surfaces, material, separate diagnostic charges and your expected insurance or self-pay amount. That gives you a much more reliable cavity-filling cost than a generic online price.
