How to compare buyer quotes and published payout benchmarks.
Dental gold has no standard karat
Dental noble alloys can contain gold, palladium, platinum, silver, and base metals in different proportions. The ADA terms “high noble,” “noble,” and “predominantly base” classify gold plus platinum-group-metal content; they do not state a fixed gold percentage. In particular, “high noble” does not mean 60% gold.
Use net alloy weight and verified gold content
Exclude porcelain or ceramic, cement, tooth residue, and other nonmetal material from the entered weight. Use the gold percentage stated by the manufacturer or a laboratory, refiner, or qualified professional. Do not remove dental work yourself or invent a purity when composition is unknown.
Dental gold value formula
Net dental-alloy grams × verified gold percentage ÷ 100 ÷ 31.1034768 × the visible pure-gold price per troy ounce = theoretical contained-gold value. The calculator keeps full precision and displays a rounded dollar result.
Value every reported precious metal together
This result excludes palladium, platinum, and silver. If an assay reports those percentages, use the precious metal assay calculator to value gold, silver, platinum, and palladium from one net weight, then transfer the components to the mixed-metal basket.
Frequently asked questions
How much is my dental gold crown worth?
A defensible contained-gold value requires the crown's net alloy weight and verified bulk gold percentage. Enter both here, then compare the result with actual buyer quotes and fees.
Is there a standard dental gold karat?
No universal karat applies to dental gold. Dental alloys vary widely, so a color, age, crown type, or trade category cannot replace documentation or professional assay.
Does high noble mean sixty percent gold?
No, high noble refers to combined gold and platinum-group-metal content and includes a separate minimum gold threshold. It must not be entered as 60% gold without an assay stating that result.
Can gold-colored dental work contain no gold?
Yes, appearance alone does not establish gold content. Dental restorations can use noble, predominantly base, ceramic, or other materials, so verify composition before calculating.
What weight should I enter for dental gold?
Enter only the net dental-alloy weight documented or measured by a qualified professional. Porcelain, ceramic, cement, tooth residue, and other nonmetal material do not belong in the metal weight.
Can I calculate dental gold without an assay?
No defensible gold calculation is possible when both composition and net alloy weight are unknown. Ask a qualified buyer, refiner, laboratory, or dental professional for documented measurements.
Does this include palladium platinum or silver?
No, this calculator values only the documented gold component. Use the precious metal assay calculator when one report states separate gold, silver, platinum, or palladium percentages.
Will a buyer pay the calculated dental gold value?
No buyer payment is guaranteed. Assay, recovery loss, refining, shipping, fees, lot size, and margin can reduce net proceeds, so compare written dollar quotes on identical terms.
