Cavities Filling Cost: What Determines What You’ll Pay
Wondering “how much does a cavity filling cost?” You’re not alone. For many patients, one of the biggest questions when visiting a dentist is the cost. The price of cavities filling can vary widely, depending on multiple factors. In this guide, we’ll break down everything about cavity filling cost, what variables affect it, how to manage costs, and what you can expect at South Gate Smile Dental, your trusted dental clinic in South Gate, CA.
What Is a Cavity Filling? (Why You Need It)
When decay attacks a tooth, the damaged area needs to be cleaned out and sealed to prevent further damage. That restoration is called a dental filling. Fillings restore both function and aesthetics. Without them, decay can worsen, possibly requiring a more expensive procedure such as a root canal or extraction.
At South Gate Smile Dental, whether you walk in as an emergency dentist near you or come in for a routine check, we evaluate the cavity's severity and recommend the best filling type—balancing durability, cost, and appearance.
Price Ranges for Cavity Fillings in the U.S.
Based on industry data, here’s a typical cost breakdown for filling a single cavity (per tooth) without insurance:
Filling Type | Typical Price Range* |
Amalgam (metal) | ~$50 – $150 (or more depending on extent) |
Composite (tooth-colored) | ~$90 – $300+ |
Porcelain / Ceramic / Inlays | $300 – $1,000+ |
Gold / Premium Materials | Up to $1,000+ or more depending on size & material |
* These are rough U.S. averages. Your actual cost may differ, especially in California or in urban areas like Los Angeles or South Gate.
For example, Cigna notes that average cavity filling costs often start around $160 for amalgam or composite types. GoodRx reports a broad range of $100 to $1,150 depending on material, location, and complexity.
What Factors Influence the Cavities Filling Cost?
Costs vary due to many variables. Here are the top factors:
Size & Depth of the Cavity
A shallow, small cavity is much cheaper to fill than a deep one extending into multiple surfaces or near the pulp. More decay means more drilling, more materials, and more labor.
Tooth Location & Number of Surfaces
Molars or back teeth generally cost more because they are harder to access, require more material, and endure higher bite force. Multi-surface cavities are more expensive than single-surface ones.
Material Choice
Amalgam fillings are cheaper but less aesthetic. Composite and ceramic (tooth-colored) fillings cost more but look better. Premium materials like porcelain or gold further drive up pricing.
Dentist Experience & Technology
A highly qualified dentist or implant dentist may charge more due to expertise. If they use advanced techniques (laser prep, digital scanning), expect higher fees.
Location & Overhead
Dental practices in urban areas or high-rent districts like Los Angeles typically have higher overhead, which reflects in filling prices. South Gate, being part of the LA metro, may see slightly elevated costs.
Additional Procedures
X-rays, anesthesia, sedation (if needed), or treatment of adjacent issues (gum work, core buildup) can increase the total cost.
Insurance & Payment Plans
Your dental insurance benefits play a big role in your out-of-pocket cost. Many plans cover 50%–80% of a basic filling after deductibles. If you lack insurance, offices like ours may offer financing or payment plans to make it more manageable.

How Much Will You Pay at South Gate Smile Dental?
While we must evaluate each case individually, here’s a rough estimate for our region (Southern California / South Gate):

How to Save or Manage Your Cavity Filling Cost
Use Dental Insurance Wisely
Choose a dentist who is in-network to minimize extra costs. Verify whether composite vs metal fillings have different coverage terms.
Get Multiple Quotes
Ask for detailed estimates from a few trusted dentists. Compare costs for the same material and procedure type.
Consider Payment Plans or Dental Financing
Many clinics offer in-house plans or partner with third-party lenders to help spread costs over time.
Preventive Care
Regular exams, cleanings, fluoride treatments, and dental sealants reduce the risk of cavities in the first place—saving you money in the long run.
Risks of Delaying Cavity Fillings
Putting off a cavity filling can lead to complications that cost significantly more:
Decay can spread deeper, leading to root canals or extractions
Infection or abscess formation
Pain, sensitivity, and difficulty chewing
Getting a filling early is almost always cheaper, safer, and less invasive than repairing greater damage later.
Frequently Asked Questions
Q: Does a cavity filling hurt? With local anesthesia, you shouldn’t feel pain. You may experience mild sensitivity for a few days afterward.
Q: How long does a filling last? Amalgam fillings often last 10–15 years; composite 5–10 years; porcelain or inlays can last 15+ years with proper care.
Q: Can a filling fail? Yes — due to wear, fracture, secondary decay, or failing bonding. That’s why regular checkups are crucial.
Q: Will insurance cover my filling? Most dental insurance plans classify fillings as “basic procedures” and cover a significant portion after deductibles. Always check your plan details.

Q: Should I choose composite or amalgam? It depends on aesthetics, durability, cost, and the tooth location. For visible front teeth, composite is popular. For back teeth or cost-sensitive cases, amalgam may suffice.
