Dental Gold Value Calculator: Crowns, Bridges and Fillings

What Dental Gold Actually Is

Dentists never used pure gold for chewing surfaces — too soft. What's in your envelope is a casting alloy, and the trade sorts these into three families.

Precious (high-noble) alloys are the good news: typically around 60–85% gold by weight, blended with palladium, platinum, and silver for hardness. This was the standard for quality crowns and inlays for most of the twentieth century, which is exactly why older dental work — the crown your father had placed in 1975 — tends to be worth the most. In karat terms these alloys land roughly between 14K and 20K equivalent.

Semi-precious (noble) alloys contain meaningfully less gold — often somewhere in the 20–50% range — with more palladium and silver doing the structural work. Still worth real money, but the per-gram value drops accordingly.

Non-precious (base metal) alloys are mostly nickel, chromium, or cobalt with little or no gold. They look silvery, weigh light for their size, and have essentially no scrap value. A magnet is a useful first screen: gold alloys don't stick, many base-metal castings do — the same quick checks covered in how to test gold at home apply here.

The catch: without paperwork from the dental lab, you cannot know the exact alloy by looking. That single fact shapes everything below, including who should buy it from you.

What a Crown Weighs (Less Than You Fear, More Than You Think)

A full-cast gold crown — the all-metal kind that covers an entire molar — typically weighs 2 to 3 grams. Big molar crowns run heavier, small premolar crowns and partial coverage lighter. A three-quarter crown or a large onlay might be 1–2 grams; a little inlay can dip under a gram. Bridges scale up with the span: a three-unit bridge (two anchor crowns plus the suspended replacement tooth) commonly comes in around 4–6 grams of metal.

Put that in jewelry perspective. At 2.5 grams and a 70% gold alloy, one crown carries 1.75 grams of pure gold — more than many 10K pendants, in a package the size of a corn kernel. People discard these because the object looks like dental debris rather than treasure. Refiners count on the opposite instinct from the people who mail them in.

Weigh yours on a 0.1-gram pocket scale before estimating anything. And note what the scale can't tell you: a porcelain-fused-to-metal crown might read 3 grams while its metal substructure is barely 1.5 grams, with ceramic accounting for the rest. Which brings us to the deductions.

Porcelain, Tooth and Cement: What Comes Off the Math

Buyers pay for recoverable metal, not gross weight, and dental gold arrives carrying passengers. Porcelain is the big one: PFM (porcelain-fused-to-metal) crowns wear a ceramic jacket that can be a third to half of total weight. Tooth structure is common — extracted teeth with crowns still cemented on, or fragments left inside a crown that came off whole. Cement, amalgam, and debris add a little more.

A refiner handles this honestly through processing: everything goes into the melt, ceramics and organics burn off or separate into slag, and you're paid on the assayed metal that remains. You don't need to remove anything yourself — and shouldn't try. Chipping porcelain off with pliers accomplishes nothing except possibly losing metal flakes; the refiner's furnace does it perfectly.

Where this becomes a negotiation problem is with local buyers who price by gross weight and eyeball. A pawn counter looking at a 3-gram PFM crown either refuses it outright or applies a brutally conservative discount — assuming, say, 1 gram of low-grade metal — because they have no assay furnace and price their uncertainty against you. When estimating your own lot in the dental gold value calculator above, do the deduction yourself: count only metal weight (subtract roughly a third to half for PFM ceramic), and use a gold percentage from the alloy families above. Conservative inputs now prevent disappointment later.

Typical Dental Work, Valued at Today's Prices

Here's the reference table, computed at an assumed gold price of $4,400 per troy ounce ($141.47 per gram of pure gold). Ranges reflect both weight variation and the alloy spread:

Two readings of this table matter. First, the melt values are real money — a couple of old crowns can fund a very nice weekend — but they are melt values; apply a payout percentage (refiners typically pay 70–90% of melt on assayed lots) to get your check. Second, the ranges are wide because the alloy is unknown until assay. That's not a flaw in the table; it's the honest shape of the problem, and it's why the gold melt calculator asks you for a purity input rather than pretending to know. If you want a single planning number for an average full gold crown, $200–$250 of melt value is a reasonable middle, with the payout check landing somewhat below that.

Why Refiners — Not Pawn Shops — Are the Right Venue

For jewelry, where you sell is a rankable spectrum — we rank it in where to sell gold. For dental gold, the spectrum collapses to basically one good answer: a refiner that advertises dental scrap processing and pays on assay.

The reason is informational, not moral. A hallmarked 14K ring tells every buyer its purity; the buyer's only job is weighing it. A crown tells nobody anything. The pawn shop's acid kit can confirm "contains gold" but can't distinguish a 40% alloy from a 75% one with any confidence — so the shop protects itself by assuming the worst and offering accordingly, when it accepts dental gold at all. Many simply don't.

An assay-based refiner inverts this. Your lot is melted into a homogeneous button, sampled, and analyzed — typically by X-ray fluorescence or fire assay — and you're paid a stated percentage of the measured precious metal content. The uncertainty that crushed your pawn-shop offer disappears, because nobody is guessing anymore. Reputable dental refiners publish their payout terms, report the assay results with your settlement, and return your material or pay a guaranteed minimum if you reject the offer.

The practical playbook: accumulate everything (single crowns are worth sending, but batching the family's dental history into one envelope amortizes any lot fees), photograph it, ship insured, and compare two refiners' published terms before choosing. The difference between a 50%-of-guessed-value pawn offer and an 85%-of-assayed-value refiner check, on the same crowns, is routinely a factor of two or more.

The Palladium and Platinum Bonus Nobody Claims

Here's the part of dental scrap that even sellers who do everything else right tend to miss. Precious dental alloys aren't gold diluted with junk — the dilutants are often palladium and platinum, precious metals in their own right that trade for serious money per ounce. A classic high-noble alloy might run 70-something percent gold with several percent palladium and a few percent platinum; many "white" dental alloys that look like cheap steel are actually palladium-dominant and quite valuable.

This is exactly where the choice of buyer compounds. A jewelry-oriented buyer quotes you on gold content alone — palladium and platinum ride along in the melt as a silent gratuity to the buyer. A proper dental refiner assays for all precious metals and itemizes them in your settlement: so many grams gold, so many palladium, platinum, sometimes silver, each priced at its own market rate. On a typical gold crown, the palladium-platinum line might add a modest amount — some extra dollars to a few tens of dollars — but on palladium-heavy white alloys, it can be most of the value. The World Gold Council tracks gold's industrial and dental uses among demand categories; the dental trade has been shifting away from precious alloys for decades, which means the crowns coming out of mouths today are the legacy stock of a richer era. Don't let the white ones fool you into the trash.

One Crown, Worked All the Way Through

Let's value a real-world specimen: a full cast gold crown from a molar, removed during dental work, no porcelain, weighing 2.5 grams on a pocket scale.

Estimate the alloy. It's yellow, heavy for its size, non-magnetic, and was placed in the 1980s — a classic high-noble profile. We'll assume 70% gold, a defensible middle for that era.

Compute gold content. 2.5 g × 0.70 = 1.75 g of pure gold.

Apply the price. At our assumed $4,400/oz ($141.47/g): 1.75 × $141.47 ≈ $248 melt value.

Project the check. A dental refiner paying 70–90% of assayed value lands between $173 and $223 on the gold alone — and if the assay finds, say, a few percent palladium, the settlement nudges up from there. Compare the alternatives: a pawn counter, if it takes the crown at all, might assume 40% purity and pay half of that guess — call it $70–$80. Same crown, roughly a threefold spread, decided entirely by where the envelope goes.

If your crown is PFM rather than full gold, rerun the math with the ceramic deducted: a 3-gram PFM crown with maybe 1.5 g of 50% alloy holds 0.75 g of gold — about $106 melt, $74–$95 from a refiner. Still worth the stamp. You can sanity-check any of these against the scrap gold calculator by entering metal weight and your purity estimate, or run live numbers through the gold calculator as prices move.

When the Tooth Comes Too: Ethics and Logistics

Now the awkward case: the crown is still cemented to an extracted tooth, or it's grandpa's, and the family isn't sure whether selling it is even... done. Short answers: yes, refiners handle this every day, and yes, it's legitimate.

On whose property it is — dental work that was paid for and placed in your mouth is yours, including after extraction. Ask the dentist to return crowns and bridges removed during procedures; most will hand them over as a matter of course, but they generally won't volunteer if you don't ask, and discarded means gone. For a deceased relative, dental gold is simply part of the estate, like a watch. Whether the family feels comfortable recovering it is a personal call — but the metal's value doesn't expire while you decide.

On logistics, the checklist:

• Don't separate the crown from tooth material yourself. Pliers and hammers lose metal and accomplish nothing the refiner's furnace won't do better.
• Clean and disinfect simply — a soak in an antiseptic solution, then dry. Refiners process biological residue routinely, but courtesy and shipping hygiene both favor a rinse.
• Seal items in a small zip bag, then a padded mailer. Crowns are tiny; loose ones vanish into envelope corners.
• Photograph and inventory before shipping, and insure the package for your estimated melt value.
• Confirm the refiner accepts crowns with tooth structure attached — nearly all dental refiners do, and their terms will say so.

One last note for estates: if the dental gold rides along with jewelry into a larger inheritance sale, the tax treatment follows the same stepped-up-basis rules as other inherited valuables. Not tax advice — for a substantial estate, that conversation belongs with a professional.
