Dental Office Scrap Gold SOP: Standard Operating Procedure for Precious Metal Scrap

Blake Plummer has more than 15 years of experience evaluating precious metals and dental scrap, and this guide reflects the procedures he recommends to dental practices and labs nationwide.

If you run a dental practice of any size, there is a high probability that precious metal is leaving your office in the trash right now. Not because your team is careless — but because no one has ever written down what to do with a removed crown. That is exactly what a dental office scrap gold SOP solves.

This guide gives you the complete procedure: what materials qualify, how to collect and log them, how to store them securely, how to train staff, what records to keep, and how to convert accumulated scrap into a predictable additional revenue stream. Every section of this document is designed to be actionable — not theoretical. You can take what's here and implement your dental office scrap gold SOP within a single afternoon.

Why Every Dental Office Needs a Scrap Gold SOP

The reason most dental offices don't have a dental office scrap gold SOP is simple: it never seemed worth formalizing. A removed crown here, a failed bridge there — it doesn't feel like a system problem until you start doing the math.

A moderately busy restorative practice that places and replaces 10–20 crowns per month is generating meaningful precious metal scrap on a regular basis. At current gold and palladium prices, each high-noble gold crown removed during a replacement procedure is worth $75 to $200 in recoverable value. A practice doing that volume without a scrap collection system is, conservatively, leaving $1,000 to $4,000 on the table every year — often more.

Beyond the financial case, there are operational reasons to have a written dental office scrap gold SOP:

• Staff accountability: When there's no documented procedure, there's no clear ownership. A written SOP assigns specific responsibilities to specific roles, which eliminates the ambiguity that causes valuable pieces to be discarded or misplaced.
• Chain of custody protection: If a piece ever goes missing — or if a patient asks what happened to their crown — a documented chain of custody gives you a defensible record.
• Consistency across staff changes: When an assistant leaves and a new one joins, the procedure shouldn't leave with them. A written dental office scrap gold SOP survives turnover.
• Audit readiness: For practices that track scrap income, documented procedures and records are essential if you're ever audited or need to reconcile your precious metal income line.

Types of Dental Precious Metal Scrap Your SOP Should Cover

Before you can collect consistently, your team needs to know what to collect. One of the most common failures in dental precious metal handling procedures is that they don't clearly define scope — which leads to some staff collecting everything and others discarding pieces that have real value.

Your dental office scrap gold SOP should explicitly cover the following material categories:

• Full-cast gold crowns: High-noble or noble alloy cast crowns with visible yellow or white metal. These are the highest-value individual pieces in any dental scrap lot.
• Gold dental bridges: Multi-unit fixed restorations cast from precious metal alloys. A three-unit gold bridge can be worth $150–$450 depending on alloy composition and current spot prices.
• Porcelain-fused-to-metal (PFM) restorations: These have a ceramic exterior, but the metal coping underneath is frequently cast from a gold-palladium alloy. PFM pieces are regularly discarded because staff assume they're worthless. They are not.
• Gold inlays and onlays: Smaller restorations, but cast from the same high-noble alloys as crowns. Include everything.
• Partial denture frameworks: Gold alloy partial frameworks are recoverable and worth submitting with the rest of your lot.
• Failed castings returned from the dental lab: Any failed or rejected castings the lab returns to you contain the same precious metal as a finished restoration. These should go directly into the collection container.
• Sprue buttons and casting remnants: If your practice has in-house casting equipment — or if a lab returns casting remnants with failed pieces — these contain recoverable precious metal.

Collection Procedures: The First Step in Any Dental Office Scrap Gold SOP

Collection is where most dental offices fail — and it's the first stage where a well-written dental office scrap gold SOP pays for itself. The problem isn't malice — it's the absence of a single, visible, designated collection point combined with a clear instruction to use it. Here is the procedure that works.

1. Designate a single collection container per operatory. Use a small, lidded container — a labeled specimen cup, a small metal tin, or a designated plastic container. Label it clearly: "DENTAL SCRAP — PRECIOUS METAL ONLY." Place it within reach of the chairside assistant at every operatory where restorations are removed. The container should not be shared with anything else and should not move around.
2. Assign collection responsibility to the chairside assistant. At the moment a precious metal restoration is removed from the patient, the chairside assistant places it in the collection container. This step should be immediate — not "after the appointment" or "at the end of the day." The piece goes directly into the container, not onto a tray where it may be discarded during cleanup.
3. Brief the patient at time of removal. Some patients ask what happens to their removed crown. Your team should be prepared to explain that it is retained as precious metal scrap and will be recycled through a specialist buyer. This prevents confusion and sets expectations clearly.
4. Transfer operatory containers to the master collection container weekly. At a designated time each week — Friday afternoon works for most practices — the office manager or designated staff member consolidates all operatory collection containers into a single, centrally stored master collection container. This is the container that accumulates material until it is sufficient for a submission to your dental scrap buyer.
5. Log each piece at the time of transfer. When moving from operatory containers to the master container, the staff member performing the transfer logs each piece in the practice's dental gold scrap log. See the inventory tracking and recordkeeping sections below for log format details.

These five steps form the collection backbone of your dental office scrap gold SOP. Post a laminated summary of steps 1–3 inside every operatory cabinet door where dental assistants can reference it during any removal procedure.

Chain of Custody Procedures for Dental Precious Metal Scrap

In any well-designed dental office scrap gold SOP, chain of custody documentation answers a simple question: where has each piece been, and who was responsible for it at each stage? For dental practices, a complete chain of custody for precious metal scrap runs from the chairside collection moment through storage, inventory logging, submission to the buyer, and receipt of payment.

Why does this matter? Two scenarios:

First, if a piece cannot be located — whether due to a staff error, a miscommunication, or theft — a documented chain of custody tells you exactly where the breakdown occurred. Without documentation, you have no way to identify the failure point or assign accountability.

Second, if a patient ever disputes what happened to their removed restoration, your chain of custody provides a verifiable record. This is unlikely but not unheard of, particularly with high-value pieces that patients believe may have significant monetary value.

Chain of Custody Documentation Requirements

Your dental office scrap gold SOP should capture the following at each custody transfer point:

This does not require sophisticated software. A simple paper log or a shared spreadsheet managed by the office manager is entirely sufficient for most practices. The key is consistency — every transfer, every time, without exception.

Storage Procedures for Dental Scrap Gold

Dental precious metal scrap has real monetary value, and a complete dental office scrap gold SOP addresses storage with the same specificity as collection. Leaving it in an unlocked drawer in the break room or in an open container at the front desk creates unnecessary risk and sends the wrong signal to your team about how seriously the practice takes this asset.

Storage Standards by Practice Volume

Regardless of volume, the storage location should never be in a patient-accessible area. It should never be co-located with regular trash or waste. The master collection container should be clearly labeled and distinct from everything else in the area where it is stored.

Inventory Tracking Procedures: The Dental Gold Scrap Log

The core document of any dental office scrap gold SOP is the scrap log — the running record that makes your dental gold inventory procedure auditable. This is the record of every piece of precious metal scrap that enters your collection system, from removal through sale.

Your scrap log does not need to be elaborate. It needs to be consistent. Here is the recommended format.

As you log pieces throughout the month, you can use our free Dental Gold Calculator to estimate dental gold value for individual entries based on alloy type and current spot prices — useful for getting a running sense of your lot's worth before you submit. When the accumulated lot is submitted to your dental scrap buyer, add a submission row to the log noting the date, the buyer, the shipment tracking number, and the date payment was received. This closes the chain for that lot and gives you a complete audit trail. If your practice accumulates scrap across multiple operatories or over extended periods, our free dental scrap inventory log is a ready-to-use template built specifically for this purpose.

Security Best Practices for Dental Precious Metal Scrap

Security in the context of a dental office scrap gold SOP isn't about treating your staff as suspects. It's about putting reasonable controls in place that protect the practice's assets and eliminate ambiguity about accountability.

Recordkeeping Requirements for Dental Gold Scrap

The question of dental gold recordkeeping has two dimensions: what you need for internal practice management, and what you may need for tax or audit purposes.

From a practice operations standpoint, your scrap records should document every piece collected, every submission made, every offer received, and every payment accepted. These records are the evidence base for your chain of custody and your revenue tracking.

From a financial standpoint, proceeds from dental scrap sales are income. They should be reported as such. The exact treatment depends on your practice's accounting structure, which is a question for your CPA — but the records your dental office scrap gold SOP already generates are exactly what you need: buyer assay reports, payment confirmations, and your internal scrap log. Our How We Assay Dental Gold guide explains exactly how each offer and written assay report is calculated, which makes reconciling these records straightforward. For current gold and palladium spot prices used in assay calculations, Kitco's live precious metal spot prices are the industry reference standard. The World Gold Council's overview of recycled gold provides useful background on how dental scrap fits into the broader precious metal recovery market. For dental-specific alloy standards and composition guidance, the ADA's dental alloys resource page is the authoritative clinical reference. Assay calculations at the refining level are benchmarked against LBMA precious metal prices, the global settlement standard for gold and platinum group metals.

Staff Training Guidelines for Your Dental Office Scrap Gold SOP

A written dental office scrap gold SOP is only as good as the staff training that supports it. The most common reason dental office scrap procedures break down isn't the procedure itself — it's that the team was never properly trained on it, or the training happened once and was never reinforced.

Initial Training Requirements

Every staff member who may handle dental restorations — primarily chairside dental assistants and treatment coordinators — should receive explicit training on the dental office scrap gold SOP at the time of onboarding. Training should cover:

• What materials qualify for collection and what do not
• Where the operatory collection containers are located and what goes in them
• The immediate collection protocol: the piece goes in the container at the moment of removal
• Who is responsible for weekly transfers and log entries
• What to do with a piece if they are unsure whether it qualifies (hold it for office manager review, do not discard)
• Basic security protocols: who has access, what not to discuss with patients

Training Sign-Off and Documentation

After initial training, each staff member should sign a brief acknowledgment confirming they received training on the dental office scrap gold SOP. Keep these sign-offs in the staff member's HR file. This provides a defensible record that the procedure was communicated — not just assumed.

Annual Refresher Protocol

Include a 10-minute SOP review in your annual staff meeting agenda. Review any changes to the procedure, address any operational questions that have come up over the past year, and confirm that collection containers are properly placed and maintained. For practices with high staff turnover, consider quarterly reminders.

Recommended Audit Schedule for Dental Precious Metal Scrap

Your dental office scrap gold SOP should include a defined audit schedule. Audits in this context aren't financial audits — they are operational checks that confirm the procedure is working as designed.

Weekly Scrap Review Process

The office manager or designated staff member should perform the following at the end of each week:

1. Consolidate all operatory containers into the master container. Check each operatory collection container. Transfer any new pieces to the master container. Return empty operatory containers to their designated positions.
2. Log each transferred piece in the scrap log. Enter every piece by date, brief description, and staff member who collected it. Note any pieces that appear to be non-precious material and set them aside for review before returning to the patient waste stream.
3. Confirm the master container is secured. Confirm the lockbox or storage location is properly secured before end of day.
4. Note any irregularities. If the log entries don't match what's in the master container, document the discrepancy and investigate before the following week. Don't let gaps accumulate.

Monthly Precious Metal Audit

Once per month, the office manager should perform a slightly deeper review:

1. Review the month's scrap log entries. Confirm that the number of pieces logged matches expectations based on your procedure volume that month. If your practice performed 15 crown replacement procedures and the log shows 4 entries, something is missing.
2. Visually verify the master container contents against the log. Count and describe what's physically in the container. It should correspond to the cumulative log entries since the last submission.
3. Assess whether a submission to the buyer is warranted. If you've accumulated a meaningful lot — general guideline: 10+ grams of material, or any time more than 90 days have passed since the last submission — plan your next shipment.
4. Record the monthly audit result. A simple one-line note in the scrap log is sufficient: "Monthly audit — [date] — [number of pieces] in container — no discrepancies / [note any discrepancies]."

Annual SOP Review

Once per year, the practice owner and office manager should review the complete dental office scrap gold SOP together and ask: is this procedure working? Are there operatory or staff situations that the current procedure doesn't address? Have there been any discrepancies in the past year that suggest a gap in the chain of custody? Update the written SOP accordingly and redistribute to staff.

Common Mistakes Dental Offices Make Without a Scrap Gold SOP

After working with dental practices across the country, the failure modes for practices without a dental office scrap gold SOP are consistent and predictable. Here are the most common ones — and how your SOP prevents each of them.

Choosing and Vetting Your Dental Scrap Buyer

Your dental office scrap gold SOP is only as strong as the buyer relationship at the end of it. An SOP that captures every piece and documents every transfer but then routes the material to a general gold buyer that ignores palladium content is still leaving money behind — just at a different stage of the process.

Your SOP should name a vetted specialist buyer and include the criteria for that vetting decision. For detailed guidance on how to evaluate dental scrap buyers, including the seven questions to ask before sending a single piece, see our complete buyer evaluation guide. Before you submit your first lot, you can also use our dental gold value calculator to calculate dental crown value and get a ballpark figure to compare against any offer you receive.

At minimum, your named buyer should meet the following criteria:

Dental Gold Experts meets all of these criteria. Blake's 15+ years in precious metals evaluation, combined with deep familiarity with dental alloy classifications and current commodity pricing, makes Dental Gold Experts the specialist buyer your dental office scrap gold SOP should name by default. Our dental gold assay process walks through exactly how each submission is tested and valued, so there's no guesswork about how your offer is calculated. Learn more about the process and get answers to common questions before your first submission.

Dental Scrap Gold SOP for Dental Labs

Everything in this guide applies to dental labs — and in most cases, labs have even more to gain from a written dental office scrap gold SOP than clinical practices do. Labs generate precious metal recoverable material at multiple stages of the workflow: casting sprues and buttons, failed castings, grinding and polishing waste that contains precious metal particles, and any returned or rejected restorations from clinicians.

Lab-specific additions to the core SOP framework:

• Casting waste collection: Every casting session generates sprues, buttons, and overflow material. These should go into a designated casting waste container immediately — never into general waste.
• Grinding and polishing waste: This is a category that many labs overlook entirely. Grinding wheels, polishing cloths, and suction filters that have accumulated precious metal particles are recoverable. Many specialist dental refining programs include procedures for collecting and processing this category of material.
• Client-returned failed units: When a clinician returns a failed restoration to the lab, that piece has the same precious metal value it had before the failure. It should go directly into the collection container, not into a parts drawer or a trash bin.
• Alloy lot documentation: Labs should maintain records of the specific alloy brands and compositions they use. This documentation gives the buyer additional context for accurate valuation and eliminates guesswork on alloy identification.

For labs that serve multiple clinics, or for multi-location and group practices coordinating scrap collection across several offices, our Dental Gold Referral Program can streamline submissions and rewards across locations — worth reviewing alongside your SOP rollout. For high-volume labs, the financial impact of a well-run dental office scrap gold SOP is substantial.

Dental Office Scrap Gold SOP Implementation Checklist

Use this checklist to roll out your dental office scrap gold SOP in a single afternoon. It condenses the procedures above into the sequence an office manager can work through step by step.

Conclusion: Your Dental Office Scrap Gold SOP Starts Today

A dental office scrap gold SOP is not a complex undertaking. It is a written procedure, a designated container, a simple log, a trained team, and a vetted buyer. Most practices can have all of these in place within a single afternoon.

The practices that benefit most from a written dental office scrap gold SOP aren't the ones with the most material — they're the ones that are most consistent about collecting and submitting it. A solo practitioner who removes four gold crowns a month and submits quarterly is recovering real money that previously went in the trash. A high-volume restorative practice with the same system might be recovering $3,000–$8,000 per year that was previously invisible.

The first step is the same in both cases: implement your dental office scrap gold SOP — designate the container, write the procedure, assign the roles, and request your first free shipping kit from Dental Gold Experts. Everything else follows from there.
