Diamond Dental Lab

Off the main drag of San Dimas, up in a second-floor suite, Diamond Dental Lab handles the kind of precision work that keeps dental practices running smoothly. This isn’t a patient-facing clinic but a laboratory—specializing in crowns, bridges, and dentures, along with the kind of custom fabrications that require both technical skill and meticulous attention to detail. The address, 1305 W Arrow Hwy STE 203, places it in that stretch of San Dimas where the foothills start to rise, just east of the 57 freeway. Feedback so far is sparse but flawless: a 5.0 rating based on two Google reviews, which, for a lab, suggests the dentists relying on it aren’t finding much to complain about.

Most patients won’t ever step inside, but the work done here affects just about every dental restoration in the area. If you’re a practitioner coordinating with them, the direct line is (626) 594-4171—no frills, just the number. For anyone mapping out the location, the directions pin it near the intersection where Arrow Highway meets the quiet industrial pockets of the city. This part of San Dimas has always been more about function than fanfare, a place where the real work happens behind unmarked doors.
