Sell or Melt Down an Old Gold Crown? Many patients ask this question after a dental crown replacement, dental implant procedure, or tooth extraction. Gold dental crowns have been used in dentistry for decades because of their durability, biocompatibility, and resistance to corrosion.
When an old crown is removed during cavity treatment, cosmetic dentistry upgrades, or dental implant placement, patients often wonder whether the gold crown has resale value.
The short answer is yes—old gold crowns can often be sold or melted down, but several factors determine their actual value. These include the gold purity, weight, alloy composition, and current market price of gold.
Understanding how dental gold works is important for both financial value and oral health awareness. This guide explains everything you need to know about selling or melting an old gold crown, including how much gold it contains, where to sell it, safety considerations, and how dental professionals handle removed crowns.
What Is a Gold Dental Crown?
A gold dental crown is a tooth-shaped cap placed over a damaged or decayed tooth to restore strength, shape, and chewing function. Dentists frequently recommend gold crowns for molars and back teeth, where biting forces are strongest.
Gold crowns are commonly used in:
- Cavity treatment
- Large tooth restorations
- Cracked or weakened teeth
- Post-root canal protection
- Dental implants
- Long-term restorative dentistry
Why Dentists Use Gold Crowns
Gold alloys provide several advantages in modern restorative dentistry:
- Excellent durability
- Minimal wear on opposing teeth
- High biocompatibility
- Resistance to oral bacteria and corrosion
- Long lifespan (20–40 years in many cases)
Gold crowns are often combined with other metals such as platinum, palladium, copper, or silver to improve strength and stability.
Can Sell or Melt Down an Old Gold Crown?
Yes, you Sell or Melt Down an Old Gold Crown, and many people do. Dental gold retains value because it contains precious metals, especially gold.
However, the selling process differs from standard jewelry sales.
Key Points to Know
Old crowns can usually be sold to:
- Precious metal refiners
- Gold buyers
- Pawn shops
- Dental scrap companies
Before selling, the crown typically needs to be melted and refined to separate pure gold from other metals.
Why Buyers Are Interested
Even though dental gold is an alloy, it still contains valuable metals such as:
- Gold
- Platinum
- Palladium
- Silver
These metals are recovered during the refining process.
How Much Gold Is in a Dental Crown?
This YouTube video below explains the weight of a gold dental crown and the factors that influence it. It discusses how crown size, design, and the type of gold alloy used can affect the overall weight. The video also provides basic insights into the materials used in gold dental restorations. 🦷✨
The value of selling an old crown depends largely on how much gold is present.
Most dental crowns contain 40%–75% gold, depending on the alloy used by the dental laboratory.
Typical Composition of Dental Gold Alloys
| Metal | Typical Percentage | Purpose |
|---|---|---|
| Gold | 40–75% | Corrosion resistance and biocompatibility |
| Platinum / Palladium | 5–20% | Strength and durability |
| Silver | 5–15% | Improves casting properties |
| Copper | 5–15% | Hardness and stability |
Average Weight of a Gold Crown
A single dental crown typically weighs:
| Crown Type | Average Weight |
|---|---|
| Small premolar crown | 1–2 grams |
| Standard molar crown | 2–4 grams |
| Large restoration crown | 4–6 grams |
Because of these weights, the resale value depends on current gold prices and refining fees.
How Much Money Is an Old Gold Crown Worth?
The value of a crown varies significantly depending on weight and metal composition.
Example Value Calculation
| Factor | Example |
|---|---|
| Crown weight | 3 grams |
| Gold percentage | 60% |
| Pure gold content | 1.8 grams |
| Estimated value (market dependent) | varies |
However, buyers usually pay 60–85% of the melt value after refining.
This means the actual payment may be lower than the theoretical gold value.
