Yes, dental gold can contain real gold. However, a gold crown, bridge, or inlay usually contains an alloy rather than pure 24K gold. An alloy combines two or more metals.
Some restorations contain substantial precious metal, while others contain little or none. As a result, color alone cannot establish purity or resale value.
If you already have a crown or bridge that your dentist removed, Gold Kings can evaluate its metal content. Before visiting, you can review what Gold Kings buys, including crowns with or without porcelain.
What Is Dental Gold?
Dental gold refers to gold-containing alloys that manufacturers produce for crowns, bridges, inlays, and onlays. People also use the term loosely for old metal restorations, even when they do not know the composition.
Pure gold is soft, so manufacturers combine it with other metals to change its strength and working properties. Depending on the formula, an alloy may also contain silver, copper, platinum, palladium, or other elements.
For examples of the different formulas and colors, see Ivoclar’s dental alloy chart. Therefore, the phrase “gold crown” does not tell you the exact gold percentage.
How Much Gold Is in a Dental Crown?
There is no single percentage that applies to every crown. Manufacturers use different alloy formulas, so two similar pieces can contain very different amounts of precious metal.
The American Dental Association’s materials guide includes a classification by precious-metal content. These three categories help explain why compositions vary:
| Alloy classification | Composition by weight | What it tells you |
|---|---|---|
| High noble | At least 60% gold plus platinum-group metals, including at least 40% gold | Contains a substantial gold share, but the exact amount varies |
| Noble | At least 25% gold plus platinum-group metals, without meeting the high noble criteria | May rely on palladium or other platinum-group metals rather than gold |
| Predominantly base metal | Less than 25% gold plus platinum-group metals | May contain little or no gold |
For example, “noble” does not mean “at least 25% gold.” Palladium can account for that category’s precious-metal content. Likewise, a high noble classification gives a minimum gold percentage, not an exact test result.
Age does not establish purity either. An older crown may contain a high gold percentage, but its date alone cannot confirm that.
Is Dental Gold 10K, 14K, or 18K?
A crown often lacks the familiar karat stamp you might find inside a ring. Instead, a buyer evaluates the metal composition.
Karat numbers still offer a useful comparison because they express gold as a share of the alloy:
- 10K: about 41.7% gold
- 14K: about 58.3% gold
- 18K: 75% gold
- 22K: about 91.7% gold
For example, an alloy containing 75% gold has the same gold fraction as 18K jewelry. However, you should not assume a crown is 18K just because it looks yellow.
Our gold karat and purity guide explains these percentages in more detail.
Can Color Tell You What the Metal Contains?
Color provides a clue, but it does not prove composition. A yellow restoration may contain substantial gold or a much lower amount. Similarly, white or silver-colored metal may contain valuable elements.
Other metals can change an alloy’s color. In addition, porcelain may cover much of the metal framework in a crown or bridge.
A base-metal crown is not necessarily fake or counterfeit. It may simply use a different material for its original purpose. For resale, the useful question is which recoverable precious metals the piece actually contains.
Therefore, avoid sorting old crowns into valuable and worthless piles based only on appearance.
How Do Buyers Test Dental Gold?
At Gold Kings, we use professional XRF testing to help identify precious metals. XRF measures the elements in the exposed area, which helps us assess an alloy’s composition.
However, a surface reading does not automatically describe every part of a restoration. Coatings, uneven surfaces, and covered metal can complicate the result.
Instrument manufacturer Evident explains these limits in its gold testing guide. It also recommends readings from multiple areas when evaluating an item.
For that reason, a buyer should consider the piece’s construction alongside its test results. Additional evaluation may be necessary when the exposed surface does not represent the whole item.
Several crowns can also contain different alloys, even if they came from the same person. Consequently, a buyer should not assume one reading applies to an entire collection.
You can learn more about the process in our guide to how an XRF gold tester works.
What Affects Dental Gold Resale Value?
Identifying precious metal is the first step. Next, the buyer must connect the composition, usable metal weight, market prices, and processing costs to an offer.
Actual Metal Weight
A restoration may contain porcelain, cement, or attached tooth material. Those materials add weight, but they do not add gold value.
Therefore, the full weight on a scale may overstate the amount of metal available for recovery. Ask how the buyer accounts for non-metal material before comparing offers.
Gold Percentage
An alloy containing 70% gold has more gold per gram than one containing 30%. However, weight still matters: a larger piece with lower purity may contain more total gold.
Both measurements must work together. Purity alone cannot tell you the final value.
Other Precious Metals
Platinum, palladium, and silver may also contribute value. However, buyers differ in which metals they recover and include in an offer.
Ask whether the quote includes any of these elements. A test that detects a metal does not guarantee a separate payment for it.
Market Prices and Processing Costs
Precious-metal prices change, so the same material can receive different offers on different dates. Buyers also allow for recovery costs, refining, and their margin.
As a result, estimated metal value and a cash offer are different figures. Our dental gold value guide explains the pricing side in more detail.
A Simple Gold Content Calculation
Suppose a crown contains 3 grams of actual metal, and testing shows that the alloy contains 70% gold. The calculation is:
3 grams × 0.70 = 2.1 grams of gold
This example assumes the 3 grams exclude porcelain, cement, and other non-metal material. Otherwise, the calculation would overstate the gold content.
To estimate the gold component’s metal value, multiply 2.1 grams by the current pure-gold price per gram. Any recoverable platinum, palladium, or silver requires a separate calculation.
Finally, compare that estimate with the buyer’s explanation of the actual offer. The example shows how to calculate gold content; it does not promise a payout.
Do Old or Broken Crowns Still Have Value?
Yes, a broken or worn crown may still contain recoverable precious metal. Scratches and an unattractive finish do not automatically erase that value.
Unlike a piece of collectible jewelry, scrap usually does not need an appealing appearance. Instead, the buyer focuses on composition and the amount of metal available.
If you find old restorations in an estate or keepsake box, set them aside for evaluation. Even a small piece can contain gold, although size alone does not establish an offer.
Questions to Ask Before Selling
A useful evaluation should explain more than a single dollar figure. Before accepting an offer, ask:
- What did the testing show about the alloy?
- How much of the total weight represents metal?
- Which precious metals does the offer include?
- What market prices support the calculation?
- How do refining or processing costs affect the payment?
In addition, mention whether you have one crown or several pieces. If you still have an alloy card or lab record, bring it as supporting information.
Clear answers make quotes easier to compare. You can then decide whether an offer suits you.
Frequently Asked Questions
Is Dental Gold Pure 24K Gold?
Gold crowns and bridges usually contain alloys rather than pure gold. Manufacturers combine metals to achieve the properties they need, so testing provides a better answer than assuming 24K purity.
Does Every Gold Crown Contain the Same Percentage?
No. Alloy formulas vary, and even similar-looking crowns can have different compositions. Therefore, buyers should not apply one assumed purity to every piece.
Can a White Crown Contain Valuable Metal?
Yes, some white metal alloys contain palladium, gold, or other precious metals. However, other restorations use base metals or ceramics. Appearance alone cannot tell you which material you have.
Can I Sell a Crown That Still Has Porcelain Attached?
Gold Kings evaluates crowns with or without porcelain. However, porcelain adds no precious-metal value, so the buyer must account for it when assessing weight.
Is One Small Crown Worth Bringing In?
A single crown may contain recoverable precious metal. Its value depends on the alloy and metal weight, so an evaluation can help you decide whether to sell.
