> Across 28,438 dental products available from three or more distributors, the typical SKU''s highest-priced distributor charges 26.5% more than the lowest. One in seven SKUs has a spread above 50%. Same product. Same manufacturer. Same pack size.
For most dental practices, "distributor pricing" is something that happens to them. The rep quotes a rate, the office manager places the order, and the line item lands on a P&L two weeks later. Whether that price was good, average, or top-of-market is a question almost nobody answers in real time.
We took a different look. Using the catalog and offer data inside the Trinity Group Purchasing (TGP) platform, we analyzed every dental SKU available from at least three distinct distributor sources — 28,438 products in total — and measured how far apart the highest and lowest distributor prices sat for the same item. The result is a clean view of how much "the market price" actually moves across a single SKU in 2026, and where the volatility concentrates.
Distributor names are anonymized throughout. Absolute prices are not disclosed — those belong to the practices and the contracts that earned them. Everything below is presented as relative spreads, ratios, and percentiles.

|---|---|
| SKUs analyzed | 28,438 |
| Distinct distributor sources | 35+ (top six cover the majority of volume) |
| Manufacturers represented | 1,700+ |
| Minimum distributors per SKU | 3 |
| Maximum distributors on a single SKU | 11 |
Every SKU in this dataset has been quoted by at least three distributors, ensuring the spread reflects real competition for the same product — not a one-off mismatch in pack size or unit of measure.
The headline numbers
Spread is calculated per SKU as `(highest distributor price − lowest distributor price) ÷ lowest distributor price`. Across all 28,438 SKUs:
| Percentile | Spread between high and low distributor |
|---|---|
| 50th (median) | 26.5% |
| 75th | 36.6% |
| 90th | 59.5% |
Translated: on a typical SKU, the highest-priced distributor charges roughly 1.27× what the lowest charges for the exact same item. On the worst quartile of SKUs, the ratio crosses 1.37×. And on roughly one in ten, it exceeds 1.60×.
How spreads are distributed
| Spread between high and low | Share of SKUs |
|---|---|
| Under 5% (essentially flat) | 0.5% |
| 5% – 15% | 11.2% |
| 15% – 25% | 32.8% |
| 25% – 50% | 41.5% |
| 50% – 100% | 8.6% |
| Over 100% | 5.4% |
Two facts stand out:
- Almost nothing is truly priced flat. Only one SKU in 200 has a spread below 5% — the "one fair market price" assumption is wrong.
- More than half of all dental SKUs (55.5%) carry a spread above 25%. That is not the long tail of edge cases; that is the body of the distribution.
Where the spreads are biggest
We aggregated spreads by manufacturer family and grouped them into broad category buckets. Manufacturer and distributor identities are anonymized. The pattern is consistent: the more commodity-like the category, the bigger the variance, because more distributors are willing to compete for it on price.
| Category (anonymized) | SKUs in sample | Median spread |
|---|---|---|
| Sterilization & barrier consumables | 279 | 51% |
| Direct restoratives & adhesives (group 1) | 1,191 | 50% |
| Hand instruments — pediatric & specialty | 376 | 47% |
| Hand instruments — general clinical | 275 | 36% |
| Direct restoratives & cements (group 2) | 1,003 | 35% |
| Burs & rotary instruments | 1,501 | 31% |
| Premium hand instruments | 3,677 | 27% |
| Restoratives & composite systems | 3,022 | 26% |
| Endodontic files & obturation | 366 | 25% |
| Cements & impression materials | 1,834 | 17% |
Sterilization and barrier products — gloves, sterilization pouches, evac tips, patient bibs — show the widest spreads in the dataset. The reasons are mechanical: low brand differentiation, high volume, and aggressive distributor promotions on private-label alternatives create a wide pricing band that practices either capture or pay through every month.
At the tight end, cements and impression materials show the narrowest spreads. These categories are protected by clinical lock-in: changing a heavy-body PVS or a luting cement requires a workflow change, so distributors price closer to manufacturer guidance and compete less aggressively on the SKU itself.
What this means in practice spend
A useful way to read these numbers: imagine a practice that buys every SKU from the highest-priced distributor available, then imagine the same practice buying every SKU from the lowest. The compounded difference, weighted by category mix, is large enough to move supply spend by roughly 2 to 4 percentage points of revenue for a typical pediatric or general practice.
In a benchmark where supply spend lands at 5% of revenue, that is the difference between supply being a 5% line item and a 3% line item — without changing a single SKU, manufacturer, or clinical protocol.
Nobody actually achieves the theoretical "buy every SKU from the cheapest distributor" floor, because the operational cost of placing forty separate orders every month is real. But almost every practice we benchmark sits closer to the highest end of the curve than to the lowest, because the path of least resistance is a single distributor account placed weekly.
Why the spread persists
Three structural reasons:
1. Distributors negotiate per-account, not per-market. Two practices ordering the same gauze pads from the same distributor on the same day can pay materially different prices, depending on rep relationship, contract age, and account volume. The "list price" most practices believe they are getting is rarely the floor.
2. Cross-distributor visibility is rare. Comparing the same SKU across distributor portals is a manual exercise — different SKU numbers, different pack sizes, different unit conventions. Without a normalized catalog, the comparison either does not happen or happens once a year.
3. Rebate timing hides the truth. A rebate that arrives two quarters later does not change the SKU-level price; it returns capital to the practice after the fact. The headline price paid stays high — and the rebate often gets quietly absorbed into general overhead rather than measured against the original line item.
What practices can do this week
1. Pull last month''s invoice for your top 20 SKUs by spend. Even without a comparison tool, the top 20 represent 60–70% of supply spend in most offices. That is the worth-an-hour list.
2. Look up each SKU at one alternate distributor. Even a single second-source quote will tell you, within five minutes, whether you are above or below the median spread in this dataset.
3. Refuse rebate-only pricing models. If the savings only arrive at year-end, the unit price on every order placed this year is by definition above what the market supports.
4. Use a GPO that normalizes the catalog. The reason TGP exists is that this comparison is operationally impossible to run on your own at any meaningful frequency. A normalized multi-distributor catalog turns a per-quarter audit project into a per-order decision.
The takeaway
Distributor pricing in dentistry is not a single number with normal noise around it. It is a wide band — with the median SKU showing a 26.5% gap between its cheapest and most expensive distributor and one in seven SKUs above 50%. The practices that recognize this and route their orders accordingly are the ones holding supply spend below 5% of revenue while their peers drift above it.
The arithmetic does not require a clinical change, a manufacturer change, or a workflow overhaul. It requires visibility.
