Owners selling equipment usually ask "what is it worth?" The better question is "what will I net, how soon, and with how much work?" A dealer trade-in and a private sale to another dentist can involve the same chair and produce very different outcomes once you subtract fees, removal, freight, your time, and the risk that the deal falls through.
This guide compares the real channels for selling used dental equipment, what each costs you, and how to combine them. For setting prices, see our companion guide on how to price your equipment when selling a practice. For a look at the buyer's side of a bulk sale, see inside a real liquidation deal.
Key takeaways
- Speed and net proceeds pull in opposite directions. Trade-ins and liquidators are fast and easy; private sales usually net more but take time and effort.
- Small, portable items (handpieces, sensors, sterilizers, curing lights) are worth selling yourself. Heavy, installed items often net more through a liquidator once removal and freight are counted.
- Marketplace fees are only part of the cost. Removal, freight, returns, and scam risk matter just as much.
- X-ray equipment, patient data on devices, and leased items (including some gas cylinders) need special handling before anything is sold.
- If you expensed the equipment when you bought it, the sale can create taxable income. Talk to your CPA before you set prices.
The channels at a glance
Costs below are described in general terms because they vary by company, region, and deal. Where a platform publishes its fees, we note it.
| Channel | Speed | What it costs you | Your effort | Main risks | Best for |
|---|---|---|---|---|---|
| Dealer trade-in | Fast, tied to a new purchase | Usually the lowest value; credit instead of cash | Very low | Credit locks you into that dealer's pricing | Owners already buying new from that dealer |
| Liquidator or used equipment buyer | Fast (days to weeks) | A wholesale price that reflects the buyer's removal, storage, and resale costs | Low | Low offers if you have one bidder | Full offices, heavy items, deadlines |
| Consignment with a used dealer | Slow (weeks to months) | A commission or split on the eventual sale | Low to moderate | Unsold items, unclear accounting | Higher-value items you can wait on |
| Auction | Scheduled; fast once set | Seller commission and fees; price set by who shows up | Moderate | Low prices at a thin auction; reserves may not be allowed | Large lots, estates, closures |
| eBay | Days to weeks | Final value fees (eBay lists 13.6 percent on the first $7,500 for most categories at the time of writing, plus a per-order fee), payment and shipping costs | High | Freight damage, returns, disputes, scams | Small, shippable items with broad demand |
| Facebook Marketplace | Days to weeks, local | No fee for local pickup sales; shipped sales carry a selling fee | High (messages, no-shows) | Scams, no-shows, policy limits on medical items | Local sales of common items |
| Dental classifieds sites | Weeks | Listing fees or subscriptions vary by site | Moderate | Smaller audience; you handle the deal | Equipment only dentists want |
| ChairsideSource marketplace | Weeks | Free to list, no commission | Moderate | You handle the deal directly | Dental-specific buyers, especially regional |
| Direct to colleagues or new grads | Varies | None beyond your time | Moderate | Friendships and awkward warranty expectations | Matched operatories, local buyers |
| Included in a practice sale | Tied to the sale | Built into the practice price | Low | Allocation of price affects taxes | Going-concern sales |
| Donation | Varies | No cash; possible deduction | Moderate | Recipients often have strict requirements | Working items with low resale value |
Fast, low-effort channels: trade-in, liquidators, and auctions
Dealer trade-in
Full-service dealers sometimes offer trade-in credit when you buy new equipment from them. It is the easiest option: the dealer removes the old equipment when installing the new, and you never deal with a buyer. The cost is value. Trade-in credit is typically well below what the same equipment brings in a private sale, and it is credit against a new purchase, not cash. It can also blur the price of the new equipment. Always get the new equipment price with and without the trade-in so you know what the credit is really worth.
Use it when: you are already buying new from that dealer, the old equipment is low value or hard to remove, and your time is worth more than the difference.
Liquidators and used equipment buyers
A liquidator buys equipment outright, usually handles removal, and resells it. You get a firm number and a date. The offer will be wholesale because the buyer is taking on disconnection labor, freight, storage, refurbishment, and the risk that some items will not sell. Our liquidation deal walkthrough explains those costs in detail.
Get more than one offer, and make each one specific: which items, who pays for disconnection and capping utilities, who restores the space, what happens to items the buyer does not want, and when payment arrives relative to removal. Some liquidators also offer consignment for higher-value pieces.
Use it when: you have a whole office or heavy installed equipment, a lease end date, or no time to manage buyers.
Auctions
Auction houses that handle medical and dental equipment run online or on-site sales, often for practice closures and estates. You pay a seller commission and sometimes fees for cataloging, photography, or removal. Buyers typically pay a buyer's premium on top of the hammer price, which tends to push bids down. Results depend entirely on who bids. A well-marketed auction with many dental buyers can do well; a thin one can sell a good chair for very little.
Use it when: you have a large lot and a firm deadline, and you can accept price uncertainty. Ask whether reserves are allowed and how removal is handled and scheduled.
Selling it yourself: eBay, Facebook, and dental marketplaces
eBay
eBay reaches the widest audience and works well for small, shippable items with clear model numbers: handpieces, sensors, scanners, curing lights, tabletop sterilizers, and parts. At the time of writing, eBay's fee page lists a final value fee of 13.6 percent on the first $7,500 of a sale for most categories (with a lower rate above that) plus a per-order fee. Check the current fee page for your category before listing.
The hidden costs are shipping, packing, returns, and disputes. Buyers can open cases for items "not as described," and heavy freight shipments add damage risk. Read eBay's current policies on medical devices before listing anything clinical, since some categories of devices are restricted.
Use it when: the item is small, in demand, and easy to describe precisely. Photograph serial numbers and function tests.
Facebook Marketplace
Marketplace is strongest for local sales. Local pickup sales carry no selling fee; shipped sales carry a percentage fee. Expect lots of messages, low offers, and no-shows. Meta's commerce policies restrict some medical and healthcare products, so review the current rules before you list. Our guide to buying safely on eBay and Facebook explains the scams from the buyer's side; sellers face a mirror image of them.
Dental classifieds and the ChairsideSource marketplace
Dental-specific listing sites put your equipment in front of people who actually buy it: dentists, office managers, and dealers. Fees and features vary; some charge per listing or by subscription.
The ChairsideSource marketplace is free to list with no commission and no dealer markup. Buyers contact sellers directly, and ChairsideSource is not a party to the transaction and does not inspect or guarantee listed equipment, so you handle payment, removal, and freight arrangements yourself. That structure keeps more money in your pocket and puts the deal terms in your hands. Posting a listing takes a few minutes.
Other options worth considering
- Colleagues, study clubs, and new grads. A local dentist building out a startup may want a matched set of operatories. Word of mouth costs nothing and avoids freight. Put the terms in writing anyway, including "as-is."
- Your practice sale. If you are selling the practice as a going concern, the equipment is usually part of the deal. Confirm what is included before selling anything separately. See retiring or downsizing.
- Donation. Charitable clinics and mission programs sometimes accept working equipment. Recipients often have specific requirements. Ask your CPA what documentation and valuation rules apply before counting on a deduction.
- Scrap and recycling. For equipment with no resale value, metal recyclers may take some items. X-ray equipment and anything with regulated components or waste need proper handling.
Worked example: one office, three strategies
All numbers below are hypothetical, chosen to show how the math works rather than to predict what your equipment will bring.
Example: a retiring dentist has three operatories (chairs, delivery units, lights), two tabletop sterilizers, a compressor and vacuum, a set of handpieces, and two digital sensors. The office lease ends in 90 days.
| Strategy A: one liquidator takes everything | Strategy B: auction everything | Strategy C: hybrid | |
|---|---|---|---|
| Gross proceeds (hypothetical) | $11,000 firm offer | $18,000 in winning bids | $7,500 small items sold yourself; $8,000 liquidator offer for the rest |
| Fees and commissions | $0 | $2,700 (hypothetical 15% seller commission) | $800 in marketplace, payment, and shipping costs on small items |
| Removal and utility capping | Included by buyer | $2,500 paid by seller | Included in liquidator deal |
| Net to seller | $11,000 | $12,800 | $14,700 |
| Time and effort | One walkthrough, one removal day | Cataloging and a fixed auction date; outcome uncertain until it closes | Several weeks of listing, messaging, and shipping small items |
| Risk | Low | Moderate: thin bidding could lower gross | Moderate: small items may not all sell before the deadline |
In this made-up case, the hybrid nets the most because the small items sell well on their own and the liquidator takes the heavy, slow items off the seller's hands. That pattern matches the general principle in our pricing guide: sell the easy items yourself and package the rest. Change the assumptions (a short deadline, no time to ship, a very active auction) and the answer changes.
Before you sell anything: the prep list
Seller prep checklist
- Inventory with make, model, serial number, and year for every item
- Service records, manuals, and original invoices gathered
- Photos of each item, its serial plate, and any wear; short videos of chairs and delivery units running
- Honest condition notes, including known issues
- Confirm nothing is leased or financed with a lien (and that the lender allows the sale)
- Confirm gas cylinders and other supplier-owned items are not included if you do not own them
- Patient data wiped or drives removed from computers, imaging devices, sensors software, and scanners
- X-ray units: know your state's notice requirements for sale, transfer, or disposal
- Disconnection plan: who caps air, water, drains, and electrical, and who pays
- Bill of sale template stating "as-is" terms, payment method, and removal date
- CPA consulted on tax effects of the sale
Regulated and sensitive items
X-ray equipment
Many states require the registrant to notify the radiation control program when a unit is sold, transferred, stored, or disabled, and some also put reporting duties on dealers and service companies. Minnesota, for example, requires notice within 30 days of a sale or transfer. Check your state before the unit leaves. Our x-ray registration guide covers the details.
Patient information on devices
Operatory computers, imaging workstations, pans, CBCT units, and scanners can hold patient images and records. Protected health information on devices you sell is still your responsibility under HIPAA. Wipe or remove drives using a method your IT provider can document, and note it in your records.
Nitrous equipment and cylinders
Flowmeters and scavenging equipment can be sold, but gas cylinders are often owned by the gas supplier rather than the practice. Return supplier-owned cylinders to the supplier. See our nitrous equipment guide.
Taxes: the part sellers forget
If you deducted the equipment when you bought it through Section 179 or bonus depreciation, your tax basis may be zero. Proceeds from the sale up to the depreciation you took are generally taxed as ordinary income. That does not change which channel nets the most before tax, but it changes what you keep. Our Section 179 guide explains recapture. Talk to your CPA, especially if the equipment is part of a practice sale where the allocation of the price matters.
Getting paid safely
- For local pickups, accept payment you can verify before the equipment leaves: cleared funds in your account or another method you trust.
- For shipped sales, use the platform's payment system so both sides have a record.
- Do not release equipment on the strength of an email or screenshot.
- Put removal dates and responsibility in writing. A buyer who misses pickup should not leave you holding equipment past your lease end.
Next steps
Sort your equipment into items that sell easily, items with real value but slow turnover, and items that cost more to remove than they return. Sell the first group yourself, get competing offers on the rest, and start earlier than you think you need to. When you are ready, post your equipment on ChairsideSource for free.
