About Mertens Diane
Devils Lake keeps its smile bright with a few trusted dental practices, one of them tucked along the quiet stretch of 4th Street. Mertens Diane sits at 310 4th St NW, a low-slung brick building that blends into the neighborhood without fanfare. Routine cleanings, fillings, and preventive care are the backbone of what they offer, along with restorative work like crowns and bridges for patients needing more than a quick polish.
Dental visits don’t have to feel like a chore when the office is just blocks from the courthouse and a short walk from local cafes. Those needing a check-up or a new set of X-rays can reach the front desk at (701) 662-8980 to schedule an appointment. The practice also handles emergency visits, so a sudden toothache doesn’t have to wait until Monday.
For anyone unfamiliar with the area, the map to Mertens Diane is straightforward—directions can be pulled up here. The building’s sign is small, so keeping an eye out for the 310 marker helps. It’s the kind of place where the door is always open during business hours, no pretense needed.
