Benco and Darby is the most instructive comparison in dental distribution, because the two companies are not trying to be the same thing. Benco sells full service. Darby sells efficiency. Practices that understand that pick correctly, and practices that do not end up disappointed by whichever one they chose.

Two different business models, not two versions of one
Benco carries cost on purpose. Fifty showrooms, a field sales force, equipment specialists and a service technician organization are expensive, and they exist because a meaningful set of practices will pay for them. When you buy a chair, someone brings it, installs it, and comes back when it fails. When you are not sure which composite to standardize on, someone comes and talks it through.
Darby removes cost on purpose. No reps, no showrooms, no service trucks. All selling happens by phone and web. It has run this way since 1948, which makes it one of the oldest low-touch models in dentistry rather than a recent price play. It maintains regional warehouses across six states with the national hub in Tennessee, and the whole operation is built around a practice that already knows what it wants and just needs it to arrive.
Neither model is better. They are priced for different customers, and the pricing difference is not a discount — it is a cost structure.
Where Darby wins
Consumables pricing. This is the point of the model. No field sales overhead means lower cost to serve, and it shows in the numbers on standard reorder items.
Speed for a practice that knows its list. If your reorder is stable and you are not seeking advice, a rep visit is friction rather than service. Web and phone ordering with no sales layer is genuinely faster.
No relationship management. Some practices want a partner. Others want a supplier. Darby is unapologetically the second, and there is nothing wrong with wanting that.
Catalog depth in consumables. 40,000+ products is not a full-service catalog, but it covers routine practice needs well. That is where the model is aimed.
Where Benco wins
Anything involving equipment. This is not a close call. Benco sells, installs and services equipment with its own technicians. Darby does not have a service organization. If your sterilizer fails, Darby is not who you call. For a practice buying or maintaining capital equipment, this alone decides it. See Autoclave Selection Guide for Dental Offices for what service coverage should factor into that purchase.
Showrooms. Being able to evaluate a chair or an imaging unit in person before a six-figure commitment is a real advantage, and Darby offers no equivalent.
A named person who knows your practice. For a newer practice, a practice standardizing materials, or a practice managing a clinical transition, a good rep earns their cost. For an established practice with a settled formulary, they may not.
Catalog breadth for specialty items. Benco's full line covers unusual and specialty needs that a consumables-weighted catalog will not.
What the availability data says about splitting
The reason "use both" is the usual right answer is not diplomacy, it is arithmetic. Across 148,952 dental products with live distributor pricing in our catalog, only 31.5% are available from more than one distributor — and the split is sharply category-dependent.
| Category | Products | Available from 2+ distributors |
|---|---|---|
| Extraction Forceps & Elevators | 1,706 | 55.0% |
| Diamond Burs | 11,393 | 54.4% |
| Composite Resins | 5,619 | 50.6% |
| Prophy Angles & Cups | 926 | 49.0% |
| Dental Cements | 1,211 | 48.8% |
| Impression Materials | 1,918 | 40.8% |
| Sterilizer & Autoclave Parts | 1,689 | 2.4% |
| Implant Fixtures & Abutments | 1,196 | 1.4% |
Read the top of that table as the Darby column and the bottom as the Benco column.
Around half of your rotary, restorative and hygiene consumables are genuinely portable, which means a low-overhead distributor can compete for them and win. Sterilizer parts at 2.4% and implant fixtures at 1.4% are effectively single-channel, and no mail-order distributor is going to change that — those come through the equipment channel or the manufacturer.
A practice running Benco for equipment, service and sole-source clinical lines, and Darby for the portable consumables, is not hedging. It is matching each distributor to the part of the catalog its model actually fits. More on the mechanics in Switching Dental Distributors: What Is Actually Portable.
When to pick just one
Darby only makes sense for an established practice with a stable formulary, no near-term equipment needs, existing service relationships for its installed equipment, and an office manager comfortable ordering without support. That is a real profile and it is well served.
Benco only makes sense for a startup or a practice mid-buildout, where equipment, layout and materials decisions are all happening at once and the support is worth more than the consumables margin. Revisit it in two years, once the formulary settles.
Both is right for most established practices with ongoing equipment needs — which is most practices.
A regional full-service independent is the option that gets left out of this comparison and often wins it. Atlanta Dental Supply (1868, employee-owned, Southeast), Amtouch Dental Supply (1991, west coast) and Midwest Dental Equipment & Supply (1988, Texas and Oklahoma) all offer full service including equipment, at a cost structure closer to Darby's than to Benco's. Midwest even maintains showrooms in four cities, which is the one thing Darby structurally cannot offer. The catch is geography — each works inside its footprint and not outside it. See Regional Dental Distributors.
Frequently asked questions
Is Darby cheaper than Benco?
On standard consumables, generally yes, and it is structural rather than promotional. Darby carries no field sales or showroom overhead, so its cost to serve is lower and its pricing reflects that. The comparison does not extend to equipment, where Darby does not offer a service organization at all, or to sole-source clinical lines where neither has leverage.
Does Darby sell dental equipment?
Darby carries some equipment but has no field service technician organization. For capital equipment that needs installation, calibration, warranty work or ongoing maintenance, a full-service distributor such as Benco, Patterson or Henry Schein is the appropriate channel. Buying a chair from a distributor that cannot service it creates a problem you will meet later.
Is Darby Dental legitimate?
Yes. Darby Dental Supply has operated since 1948, is headquartered in Jericho, New York, and is owned by Darby Group Companies, which remains controlled by the founding Ashkin family. It is one of the longest-running dental distributors in the United States. The low-touch model is a deliberate cost choice, not a sign of a marginal operation.
Who owns Darby Dental?
Darby Dental Supply is owned by Darby Group Companies, a privately held holding company controlled and operated by members of the Ashkin family, which founded the business in 1948.
Can I run Benco and Darby at the same time?
Yes, and it is a common setup. There is no exclusivity in standard distributor relationships. The practical cost is administrative — two portals, two invoice streams, two approval paths — rather than contractual. Just make sure the volume actually moves to the cheaper channel for the categories where it belongs; a second account nobody orders from saves nothing.
Which is better for a new dental practice?
Benco, or another full-service distributor, for the first year or two. A startup is making equipment, layout and materials decisions simultaneously, and support during that period is worth more than the consumables savings. Once the formulary and the equipment are settled, adding Darby for the portable consumables is the natural next step. See Starting a Pediatric Dental Practice: Supply Cost Planning.
