Is Dental Gold Worth Anything When You Sell It?
Short answer: yes, dental gold is worth money, and often more than people expect. The catch is that a gold crown is not a gold coin. You cannot read a karat stamp off it, the alloy is mixed with metals that have little resale value, and the piece is usually stuck to porcelain or old tooth structure. Here is how a buyer actually turns that little bag of crowns into a payout figure.
Most people bring in dental gold in an envelope or a pill bottle: a couple of crowns from a dentist visit, a bridge inherited from a parent, maybe a gold cap. There is no hallmark, no weight printed anywhere, and no way to eyeball what it holds. That uncertainty is exactly why dental gold gets underpaid at pawn counters and overhyped by mail-in outfits. Knowing what is really in the piece puts you in a stronger position before you hand it over.
Dental alloys were never designed to be pure gold. Pure gold is too soft to survive years of chewing, so dental labs blend it with palladium, platinum, silver, and base metals like copper and zinc for strength. The gold content ranges widely. High-noble dental alloys can run anywhere from roughly 40 percent to 75 percent gold by weight, which lands them somewhere between 10K and 18K in everyday terms. Some crowns marketed as gold contain very little precious metal at all and are mostly base alloy with a thin gold-colored finish.
That is the core problem with pricing dental gold by sight: two crowns that look identical can differ in value by a factor of three. The only honest way to price it is to test it.
How a buyer tests and weighs dental gold
A serious buyer does not guess. The piece gets cleaned of loose debris, then weighed on a calibrated scale in grams. Weight comes first because everything downstream is priced per gram of actual gold content.
Next comes testing. An XRF analyzer is the standard tool: it reads the full metal composition without damaging the piece, showing the exact percentage of gold, palladium, platinum, and silver present. For a buyer without XRF, acid testing on a scratch stone is the fallback, though it is less precise on mixed dental alloys and only estimates a karat range. If someone offers you cash for dental gold without testing it in front of you, that is a signal to slow down.
The porcelain, ceramic, or leftover tooth material attached to a crown has no value and is not gold. A fair buyer accounts for it by pricing only the recovered metal, either by estimating the non-metal portion or by refining the lot and paying on the assayed result. What you should never accept is being charged for that porcelain as if it were part of the weight working against you; you also should not expect to be paid for it.
Palladium and platinum in the alloy are worth something too. A good buyer credits those metals, not just the gold. A buyer who only pays on gold content and pockets the platinum is quietly shorting you on high-noble dental pieces, which are often loaded with palladium.
What to realistically expect at payout
Here is the honest framing. Because dental alloy is typically well below pure gold, the payout per gram is a fraction of the spot price you see quoted for gold. If spot gold is high, a gram of 16K-equivalent dental alloy still only carries about two-thirds of that value in gold, and the buyer needs a margin to cover refining and assay costs. Refiners take a cut, and small lots cost more to process per gram than large ones.
A practical expectation: for a small handful of crowns and a bridge, payouts commonly land in the tens to low hundreds of dollars, depending entirely on weight and gold percentage. A single crown might weigh one to three grams total, and only part of that is recoverable precious metal. This is real money, but it is not the windfall that mail-in ads imply.
To get the strongest number, keep a few things in mind. Weigh your pieces at home first, even on a kitchen scale, so you know roughly what you are handing over. Ask the buyer to test in front of you and show you the composition reading. Ask specifically whether they are crediting palladium and platinum, not gold alone. And compare the per-gram offer against the tested gold content, not against a headline spot price that assumes pure metal.
Sell to a buyer who prices transparently: weight, tested percentage, and a clear per-gram figure you can check. Skip anyone who quotes you a flat price for the bag before touching a scale. Dental gold is small, easy to mail, and easy to undervalue, which makes it one of the more commonly underpaid categories in the scrap market. A little prep protects you.
One last note on the pieces themselves. If a crown has sentimental value, weigh that against a modest scrap figure before you sell; the metal is worth what it is worth, and it is rarely enough to justify parting with something you would regret losing. For everything else sitting in a drawer, testing and a fair per-gram offer will turn it into cash that is otherwise doing nothing.
