Are you searching for a long-lasting dental restoration that offers exceptional durability? Gold foil restorations, particularly the D2420 two-surface application, might be the premium solution your dentist recommends. While less common in modern dentistry, this specialized technique offers unique benefits that make it worth considering for certain dental situations.
What Is a D2420 Gold Foil Restoration?
A D2420 gold foil restoration is a specific dental procedure code that refers to a two-surface gold foil filling. Unlike conventional fillings, gold foil involves placing extremely thin sheets of pure gold directly into prepared tooth cavities. The “two-surface” designation indicates that the restoration covers two distinct areas of your tooth—such as the occlusal (biting) and buccal (cheek-facing) surfaces.
Gold foil restorations differ significantly from gold inlays or crowns. While inlays and crowns are fabricated in a laboratory and then cemented into place, gold foil is directly condensed and built up in your tooth during your dental appointment.

The Clinical Process: How Your Dentist Places a Two-Surface Gold Foil
When you receive a D2420 gold foil restoration, your dentist will follow these specialized steps:
- Tooth Preparation: Your dentist creates a precise cavity preparation, removing decay while preserving as much healthy tooth structure as possible.
- Gold Preparation: Thin sheets of 24K pure gold are cut into small pieces and heated to make them more malleable.
- Layered Application: Using specialized instruments, your dentist carefully compacts layers of gold foil into the prepared cavity, building up the restoration across both tooth surfaces.
- Finishing and Polishing: The gold is meticulously shaped to match your natural tooth contours and then polished to a high shine.
The entire procedure typically requires 2-3 hours of chair time and demands exceptional technical skill from your dentist.
Health Benefits of Gold Foil Restorations
Gold foil offers several distinct advantages for your dental health:
- Biocompatibility: Gold is among the most biocompatible materials in dentistry, rarely causing allergic reactions or tissue irritation.
- Minimal Thermal Conductivity: Unlike amalgam fillings, gold foil conducts less temperature change, reducing sensitivity to hot and cold foods.
- Excellent Marginal Integrity: When properly placed, gold foil creates an exceptional seal against the tooth structure, helping to prevent secondary decay at the margins.
- Conservative Preparation: The technique requires less tooth removal compared to crowns, preserving more of your natural tooth structure.
Understanding the Costs of D2420 Gold Foil Restorations
Gold foil restorations represent a premium dental service, with costs reflecting both the material value and the specialized expertise required:
Typical Price Range
| Factors | Cost Range |
|---|---|
| Basic D2420 procedure | $900-$1,500 |
| With sedation | Add $200-$500 |
| In metropolitan areas | $1,200-$2,000 |
| Rural practices | $800-$1,300 |
The final price you’ll pay depends on:
- Geographic location: Metropolitan areas typically command higher fees
- Dentist expertise: Specialists with advanced training in this technique often charge more
- Gold market prices: The cost of pure gold directly impacts the material costs
Insurance Coverage for Gold Foil Restorations
Understanding your financial options is essential when considering this premium restoration:
- Traditional Dental Insurance: Most plans classify D2420 gold foil as a major restorative procedure, covering 50% of costs after deductibles (if covered at all).
- Alternative Coverage Options: Some plans may only reimburse the equivalent cost of an amalgam or composite filling, requiring you to pay the difference.
- Pre-authorization Requirements: Many insurers require pre-authorization for this procedure, so check with your provider before scheduling treatment.
Payment Options When Insurance Falls Short
If your insurance provides limited coverage for D2420 gold foil restorations, consider these alternatives:
- Dental Discount Plans: May offer 15-20% discounts on gold restorative procedures
- Health Savings Accounts (HSAs): Use pre-tax dollars to fund your dental care
- CareCredit or Dental Financing: Many practices offer special financing for premium restorations
- Payment Plans: Some dental offices provide in-house financing options with manageable monthly payments
Who Should Consider a Two-Surface Gold Foil Restoration?
While not for everyone, you might be an ideal candidate for D2420 gold foil if:
- You need a restoration in a location with moderate chewing forces
- You want the longest-lasting direct restoration possible
- You don’t have concerns about the gold being visible when you smile
- You have a history of fractured or failed composite fillings
- You want to preserve maximum healthy tooth structure
However, this restoration isn’t recommended if you have a history of gold allergies, severe grinding habits, or are seeking the most economical restoration option.
Alternative Restorative Options to Consider
Before committing to a gold foil restoration, discuss these alternatives with your dentist:
- Composite Fillings: Less expensive, tooth-colored, but typically less durable (5-10 years)
- Ceramic Inlays: Tooth-colored, laboratory-fabricated, but more expensive
- Gold Inlays: Similar longevity to gold foil but requires less specialized skill to place
- Amalgam Fillings: Less expensive but more visible and requires more tooth structure removal
Quick Review
D2420 gold foil two-surface restorations offer an exceptional, though rarely used, solution for restoring teeth with decay or damage across two surfaces. While demanding significant expertise from your dentist and commanding premium fees ($900-$2,000), these restorations provide unmatched longevity and preservation of natural tooth structure. Insurance typically covers only a portion of costs, making alternative financing options worth exploring. For the right candidate, this premium restoration represents an investment in dental health that can last decades.
