What to Do With Old Gold Crowns: Your Options Explained

What to do with old gold crowns: the four options compared

Most people with this question have one or two removed gold crowns in a drawer, handed back by a dentist years ago, and no clear idea whether they are worth anything or where they could go. There are four realistic paths. Three are decisions you can make yourself; the fourth is a question for a dentist.

Option 1: keep your old gold crown

Keeping is the first answer to what to do with old gold crowns, and it is a legitimate one: selling is optional. People keep old dental gold for reasons that have nothing to do with metal prices: a crown that belonged to a parent or grandparent, a piece of their own dental history they are curious about, or the wish to wait until other pieces turn up and decide about all of them at once. All of those are sound reasons, and nobody at a metal buyer should talk you out of them.

If you keep it, a little practical care helps. A crown removed from a tooth may still carry cement and small amounts of tooth material, so store it in a sealed, labelled container rather than loose in a drawer, and keep it away from children. A labelled container also makes life easier later if you or a family member decide to have it evaluated, because you will know which piece came from where.

Two cautions. Keeping a crown is not a final decision, and it does not establish what the crown contains, so avoid building expectations around it. And if the real question is whether the crown belongs to you in the first place, that is a separate subject covered in who owns extracted dental gold; this guide assumes the crown is already yours.

Option 2: sell your old gold crown

Selling is the second answer to what to do with old gold crowns. An old crown may contain recoverable precious metal, but how much cannot be established from the way it looks. Dental crowns are cast from alloys, not from pure gold. The American Dental Association's materials for indirect restorations page groups these alloys as high noble, noble and predominantly base by their gold and platinum-group content. The categories are thresholds, not measurements: a high noble alloy must contain at least 40% gold, but the actual figure in a given crown can be anywhere above that. The Cleveland Clinic's overview of dental crowns lists gold, palladium, nickel and chromium among the metals technicians use, which is why two crowns of the same colour can have very different gold contents.

If value is what will decide it for you, keep five things in mind:

• Colour is not composition. Yellow alloys vary widely in gold, some white alloys contain gold, and some yellow-toned pieces contain very little.
• Non-metal material adds no gold. Porcelain, cement and tooth structure contribute nothing to the gold content of the lot.
• Weight and composition set the figure together. A small high-gold crown and a larger lower-gold piece can contain similar amounts of gold.
• A written evaluation is what you are buying. It should show the weight, the gold percentage, the gold spot price used, the payout rate and the calculation, so the offer can be checked.
• One crown is still worth evaluating. There is no minimum quantity at Dental Gold Experts; a single crown is welcome.

This guide deliberately does not publish typical crown weights, gold percentages or dollar figures, because none of them can be verified for the crown in your hand. For the full selling process, what decides the offer and a worked example, read how to sell gold crowns. If the question is whether a small amount is worth the trouble at all, is dental gold worth selling? answers it directly.

Option 3: recycle the metal

Recycling is the third answer to what to do with old gold crowns, and it means recovering the metal, not reusing the crown. Five words get mixed together here, and they describe different steps:

• Selling transfers the crown to a buyer, who pays for the metal it contains. For most individuals this is how recycling starts.
• Melting turns the crown, together with any other scrap in the lot, into a single mass of metal.
• Assaying measures what that melted metal contains, above all its gold content, so that it can be valued.
• Recovering is the broad term for getting usable metal out of scrap.
• Refining separates and purifies the individual metals so they can be used again in new products.

Dental scrap is a recognised part of the recycled-gold supply. The World Jewellery Confederation's March 2025 recommended definition of recycled gold describes post-consumer recycled gold as "gold obtained by refining products sourced from individuals, organisations or industrial facilities in their role as end-users" and lists "dental scrap" among the products it includes. In plain terms: once an old crown is melted and refined, its gold goes back into circulation rather than staying in a drawer.

There is more than one route in. An individual usually sells to a dental-gold buyer or a refiner. A dental practice or laboratory that collects removed restorations sends its accumulated scrap on in bulk, the route described in our dental office scrap gold SOP, and some patients choose to leave a crown with the practice for that reason. Either way the metal ends up melted, assayed and refined. At Dental Gold Experts the steps a customer sees are the evaluation ones: your material is melted, the melted material is analyzed by XRF to determine its gold content, and you receive a written report and an offer based on that gold content. Porcelain is ceramic, not metal; it is not recoverable gold.

Can an old gold crown be reused?

This is the most common misunderstanding behind what to do with old gold crowns, so it is worth being precise. "Reuse" can mean three different things:

1. Reusing the crown as a restoration. A crown is made for one prepared tooth. The Cleveland Clinic's overview describes the laboratory technician using your dentist's impressions "to create your custom dental crown". A removed crown, or one that belonged to someone else, is not a stock part that can be fitted to another tooth.
2. Recycling its metal. This is possible for any metal crown and is what Option 3 describes.
3. Having recovered metal used in another manufactured item. Refined metal from dental scrap re-enters the market as metal; it is not traced back to your crown, and Dental Gold Experts does not make jewelry or other items from a customer's crown. Dental alloys are not karat-graded jewelry alloys either; the jewelry-marking rules in 16 CFR § 23.3 apply to jewelry industry products, so a jeweler asked to work an unmarked dental alloy directly may reasonably decline.

A crown that has just come off is a different situation from an old crown already released for disposal. The Cleveland Clinic lists "a loose crown" among the reasons to call your dentist, and the NHS 111 Wales advice is to see a dentist and, if you have the crown, keep it safe and take it with you. Whether it can be re-cemented is the dentist's call. Only once a dentist has confirmed a crown is finished with does the question of what to do with old gold crowns arise.

How can you tell whether your old crown contains gold?

Honestly, not by looking. Before deciding what to do with old gold crowns on the strength of their appearance, be aware that the usual clues are preliminary at best:

• A yellow appearance suggests a gold-coloured alloy, but says nothing about the percentage, and a gold-toned surface can sit over a very different metal.
• A white or silver appearance does not rule gold out. Some white alloys are noble alloys containing gold; others are base metals with none. Our guide to white dental gold covers these.
• A porcelain exterior hides the metal entirely. Porcelain has been fused to metal substructures since the 1950s, according to the ADA's materials page, and the metal underneath may be a gold alloy or a base alloy.
• Weight in the hand is a weak guide. Gold alloys are dense, but a porcelain-covered crown or a thick base-metal crown can feel substantial too.
• Dental records or an alloy name can tell you the alloy as sold and are worth keeping, but they describe a product, not the measured metal in your piece. The guide to what gold crowns are made of explains where to find them.

Those clues help you judge whether a piece is worth sending; they do not replace measurement. Avoid acid tests, filing, grinding or other home methods on a dental crown; they damage the piece, can remove metal, and still do not give you a percentage. How to identify dental gold goes through the safe visual signals, and what karat is dental gold explains why a crown has no karat in the jewelry sense. You do not have to be sure before you send: pieces you are unsure about are welcome, and base metal pieces add no gold.

What to do with old gold crowns that still have a tooth or porcelain attached

This question stops a surprising number of people from asking for an evaluation, so here is the plain answer: send it as it is. Dental Gold Experts accepts crowns still attached to extracted teeth, and porcelain-fused-to-metal crowns are accepted with the porcelain in place. The material is sorted, and non-metal material is removed as part of the melting process. Tooth structure, cement and porcelain contribute no gold, and payout calculations use the post-melt weight.

Do not cut, grind, burn, chemically strip or force apart dental material yourself. The non-metal parts never counted toward the gold content, so separating them gains you nothing, and rough handling can lose or damage metal or hurt you. If the crown is on an extracted tooth, contact Dental Gold Experts before you ship, because no handling or mailing instructions for teeth are published. Our guide to gold crowns on extracted teeth covers that case in full.

How Dental Gold Experts evaluates old gold crowns

If your answer to what to do with old gold crowns is to sell, this is the sequence, in the order it happens:

1. You request a free prepaid, insured USPS shipping label, then send your eligible dental material.
2. Your prepaid USPS package is received, and the material is sorted.
3. Everything you submit is melted together as one lot, and non-metal material is removed as part of the melting process.
4. Blake analyzes multiple spots on the melted material by XRF to determine its gold content.
5. You receive a written report showing the weight, the gold percentage, the gold spot price used, the payout rate and the payout calculation.
6. You receive an offer based on the gold content shown in your report. If you accept, payment is issued within 24 hours, usually immediately, by Zelle, PayPal, check or ACH bank transfer.

Two points follow. XRF readings are taken on the melted lot, not on each crown individually, so the report describes what you sent as a whole. And melting is irreversible, which is why keeping a crown you are unsure about parting with is the right call until you are sure. The step-by-step detail is in the dental gold assay process. Material is usually processed the day your package arrives or the next day; packages received on a weekend are processed the next business day.

What to do with old gold crowns before you send them

If you have decided to sell, these steps keep it simple:

• Confirm the crown is removed and that you own it or are authorized to sell it. Dental Gold Experts buys from sellers who own the material or are authorized to sell it. Never attempt to remove a crown from anyone's mouth; that is dental work.
• Leave porcelain and tooth material alone. Do not separate, clean, file or polish anything. Contact us first if a crown is on an extracted tooth.
• Gather other old dental gold at the same time if you have it. Fillings, bridges, inlays and partial-denture frameworks can go in the same lot, and everything is melted together as one lot.
• Keep a simple record if practical. A note of what you are sending, a photo and a weight are recommended preparation; Dental Gold Experts does not require them before you ship.
• Follow the packing instructions emailed with your label. Use a USPS Small Flat Rate Box, available free at the post office, securely tape the outside edges, attach the prepaid label and drop it at any USPS location. For larger shipments, contact us before shipping to arrange additional coverage.
