How to Choose a Dental Lab: A Practical Guide for Dentists

Picking a dental lab is one of the most consequential vendor decisions a private practice makes. The lab you work with affects chair time, patient experience, remake rates, and ultimately the reputation of your restorations. Yet most dentists choose a lab the same way they choose a coffee shop near the office, convenience, a recommendation from a colleague, or whoever happened to call last week.

Here's a more deliberate framework, drawn from what actually separates a great lab partnership from a frustrating one.

1. Look at consistency, not just one nice crown

Any lab can make a beautiful single anterior e.max under ideal conditions. The real question is what their average looks like across 50 posterior zirconia units when the prep was tight, the bite was hard to read, and the case had to ship Friday. Ask for a test case on something routine. Seat it. Note the contacts, the occlusion, the margin, and how much chair time it took you to deliver. That's the lab's real quality.

2. Turnaround that fits your schedule

Industry standard for a single-unit crown is 7–10 working days in-lab. Implant cases and full-arch work run longer. What matters more than the headline number is predictability, does the lab hit the ship date they quoted you, or does "Friday" routinely become next Tuesday?

3. A real technician on the phone

When a case has a shade question, a margin issue, or an occlusal scheme that needs discussing, you want to talk to the technician working on your case, not a customer service rep reading from a queue. Smaller and mid-sized labs almost always win on this dimension. Ask during your first call: "If I have a question on a case, who picks up?"

4. Digital workflow support

If you scan with iTero, TRIOS, Medit, Primescan, or any modern intraoral scanner, your lab needs to ingest STL or proprietary files cleanly and route them into design without manual rework. Ask which scanners they're connected to directly, what file formats they accept, and whether they print models or design model-free. A lab that's still primarily impression-driven will slow you down.

5. Materials transparency

Reputable labs will tell you exactly which zirconia, which lithium disilicate, which denture teeth, and which alloy they use, and they'll have it written on the lab slip. "We use a premium zirconia" is not an answer. "We use Katana STML for posterior monolithic and Katana YML for anteriors" is.

6. Remake policy

Things will go wrong. The right question isn't "do you remake?", every lab says yes. The right question is: "What's your remake rate, and what counts as a no-charge remake?" A lab confident in their work will answer specifically and won't try to charge you when the issue is on their side.

7. Local matters more than you'd think

Offshore and out-of-state labs can be cheaper, but you lose same-day shipping, fast remakes, and a technician you can actually reach. For most New England practices, a local lab within 1–2 day shipping radius pays for itself in saved chair time.

What to do next

Pick two or three labs that look credible on the criteria above, send each of them a single test case, ideally the same type of case, and compare the results side by side. Six weeks of real cases will tell you more than any sales pitch.
