Regional Dental Laboratory

The stretch of West 39th Street near Phillips Avenue holds more than just storefronts—it’s where Regional Dental Laboratory operates, tucked between the quiet rhythm of downtown Sioux Falls and the hum of nearby traffic. A dental lab doesn’t always draw attention, but this one sits at an address that’s easy to spot: 207 W 39th St, a location that’s as central as it gets without being flashy. No signs promise miracles; the work here speaks through precision, not promotion.

Dental laboratories are the unsung backstage of dentistry—where impressions become crowns, bridges, or dentures, all crafted to specs that dentists rely on. This isn’t a clinic with chairs and drills; it’s where materials like porcelain, acrylic, and alloys take shape under exacting standards. Some labs specialize in aesthetics, others in durability; this one handles the spectrum, from single-tooth restorations to full-arch prosthetics. No patient walks in off the street, but every dentist in the region knows the role a place like this plays in their practice.

Questions about cases or timelines? The lab’s direct line—(605) 332-6685—connects dentists to the technicians who’ll turn a scan or mold into a functional piece. There’s no front-desk small talk here; the interaction is purely professional, a back-and-forth of measurements and materials. It’s the kind of number saved in a dentist’s phone under “lab,” not advertised on billboards or bus benches.

The building itself is unassuming, a detail that fits Sioux Falls’ no-nonsense character—no neon, no grand marquee, just a address that’s easy to find via directions if you’re dropping off a case. Around here, the best recommendations come from dentists who’ve seen the lab’s work firsthand—not from flashy ads, but from results that hold up under the pressure of daily use. That’s how it’s always been in this part of town.
