How Much Gold in a Crown Is Worth? Scrap Guide
The scrap gold in a typical dental crown is worth between $60 and $250 at current precious metals market rates, with exceptionally heavy molar crowns containing high-noble alloys reaching $300 to $400+. Dental crowns are never made of 100% pure 24-karat gold because pure gold is far too soft to withstand the severe mastication forces of human chewing. Instead, dental laboratories cast crowns using proprietary dental alloys ranging from 10-karat (40% gold) to 16-karat (65% gold), frequently combined with other valuable precious metals including platinum, palladium, and silver. A standard gold crown weighs between 2.0 and 4.0 grams, containing roughly 1.0 to 2.5 grams of pure gold by weight.
Dental Gold Crown Melt Values by Tooth Classification
Dental gold classifications established by the American Dental Association (ADA) categorize alloys into three distinct tiers: High Noble alloys (which must contain at least 60% noble metal, with at least 40% being gold), Noble alloys (containing at least 25% noble metal), and Base Metal alloys (containing less than 25% noble metal, typically consisting of nickel, cobalt, or chromium). Yellow gold dental crowns almost always belong to the High Noble or Noble category, giving them substantial salvage value when removed or replaced.
Many patients overlook the value of a removed gold crown when their dentist replaces it with a modern tooth-colored porcelain or zirconia restoration. Under dental ethics codes and property law, your extracted dental restorations remain your personal legal property. Asking your dentist to return your extracted gold crown allows you to sell it to specialized dental refiners, gold bullion dealers, or refinery mail-in services rather than leaving valuable precious metal in the dentist’s scrap collection bin.
The market scrap value of a dental gold crown is determined by tooth anatomical size, alloy karat purity, and prevailing gold spot market prices.
| Crown / Tooth Type | Average Total Weight | Typical Gold Purity (Karat) | Estimated Melt Value |
|---|---|---|---|
| Incisor / Premolar (Small) | 1.5 - 2.5 grams | 10K - 14K (41.7% - 58.3%) | $50 - $110 |
| Standard Molar (Medium) | 2.5 - 3.5 grams | 12K - 16K (50.0% - 66.7%) | $90 - $190 |
| Large Full-Cast Molar | 3.5 - 5.0 grams | 14K - 18K (58.3% - 75.0%) | $160 - $320 |
| Gold-Substructure PFM Crown | 2.0 - 3.5 grams (with porcelain) | High Noble Gold Alloy | $60 - $140 (after deduction) |
| Multi-Unit Dental Bridge (3-unit) | 6.0 - 10.0 grams | 14K - 16K High Noble Alloy | $280 - $650+ |
Refinery Payout Percentages and Liquidation Outlets
Calculating the exact intrinsic melt value of a gold crown requires a simple mathematical formula based on current gold spot prices. First, determine the gross weight of the crown in grams using a calibrated digital jeweler scale. If the crown has porcelain or enamel fused to the metal (known as a PFM crown) or fragments of tooth cement and bone attached, refiners must deduct or mechanically break away that non-metallic tare weight. Multiplying the clean metal weight by the estimated gold fineness (for example, 50% for 12K alloy) yields the pure gold gram weight, which is then multiplied by the current price of gold per gram.
Hidden bonus value frequently exists within dental alloys due to secondary platinum group metals. Dental metallurgical alloys formulated to bond with porcelain or provide ultra-durable occlusion often incorporate 5% to 15% platinum and 10% to 25% palladium to raise melting temperatures and prevent oxidation. Both palladium and platinum command high industrial precious metal values. Dedicated refiners assay the entire metal composition and compensate sellers for the palladium and silver content alongside the gold.
Evaluating where to liquidate scrap dental gold ensures sellers receive fair precious metal percentages rather than steep broker markdowns.
| Buyer / Liquidation Channel | Typical Payout % of Melt | Testing Method | Best For |
|---|---|---|---|
| Specialized Dental Refiners (Mail-in) | 85% to 95% of Melt | XRF Spectrometer / Fire Assay | Multiple crowns, dentists, highest total cash return |
| Local Coin & Bullion Shops | 70% to 85% of Melt | X-ray Fluorescence (XRF) gun | Immediate cash in hand, quick local transaction |
| Local Pawn Shops | 40% to 60% of Melt | Acid scratch test / Density estimate | Quick emergency liquidation, lowest payout percentage |
| Online "Cash for Gold" Envelopes | 30% to 55% of Melt | Internal assay (often undisclosed) | High convenience, but notoriously heavy profit deductions |
| Jewelers / Custom Goldsmiths | 65% to 80% of Melt | Specific gravity / Electronic tester | Store credit toward jewelry or cash payout |
Dental Metallurgy, Precious Palladium, and XRF Testing
Porcelain-Fused-to-Metal (PFM) crowns require specialized handling during valuation. White ceramic porcelain fused over a metal coping adds significant physical bulk and weight but possesses zero scrap value. A PFM crown that weighs 3.5 grams on a scale might only contain 1.5 to 2.0 grams of actual underlying gold alloy. Specialized dental refiners dissolve porcelain using chemical strippers or crushing mills to extract every milligram of precious metal accurately.
Testing dental gold presents challenges for amateur buyers using traditional nitric acid testing kits. Because dental alloys combine gold with copper, zinc, platinum, and palladium, acid drop testing on touchstones frequently produces inconclusive or distorted reactions. Professional precious metal refiners utilize non-destructive X-Ray Fluorescence (XRF) spectrometry analyzers that shoot an X-ray beam into the alloy, analyzing elemental wavelength emissions to display the exact percentage of gold, palladium, platinum, and silver within seconds.
Tax implications on selling scrap personal dental restorations are generally nonexistent for individual consumers. The Internal Revenue Service (IRS) treats discarded personal dental crowns as personal property sold at a loss relative to the original medical cost. Because you originally paid your dentist $1,000 to $1,800 to manufacture and cement the crown years ago, selling the scrap metal for $150 represents a net capital loss rather than taxable capital gain income.
How to Sell a Used Dental Gold Crown for Maximum Cash
Follow this step-by-step guidance on recovering your extracted crown, cleaning dental cement, testing precious metal purity, and securing top refinery payouts.
Request Your Extracted Crown from the Dentist
Before or immediately after your extraction or replacement procedure, ask your dentist to place your removed gold crown into a sealed sterile pouch.
Clean and Weigh the Crown on a Gram Scale
Boil the crown briefly or soak in isopropyl alcohol to sanitize, chip away loose dental cement carefully, and weigh the metal on a 0.01g digital scale.
Check Current Spot Gold Prices per Gram
Look up the live precious metal spot price per gram of gold, noting that dental alloys typically contain between 40% and 65% pure gold by weight.
Obtain Quotes from Reputable Coin Shops or Refiners
Avoid discount cash-for-gold mailers; instead, visit local coin dealers with XRF analyzers or send to accredited dental scrap refiners paying 85%+ melt.
Verify Assay Purity and Receive Payment
Review the written assay report confirming elemental percentages of gold, palladium, and platinum, and collect payment via check, wire, or cash.
