About Kourosh Nakhaei, DDS

Dental care isn’t just about routine checkups—it’s about finding a provider who handles everything from fillings to more specialized treatments without the usual hassle. Along Highway K in O’Fallon, there’s a practice that covers the basics and then some, whether you’re due for a cleaning or need something like crowns or extractions. No frills, just the kind of place where you can get preventative care or cosmetic work done without the back-and-forth of referrals.

Kourosh Nakhaei, DDS operates out of 2990 State Hwy K, O’Fallon, MO 63368, a stretch that’s easy to reach whether you’re coming from the newer subdivisions or the older parts of town. The practice holds a perfect 5.0 rating from 7 reviews, which, while not a massive sample, suggests a consistency that’s hard to argue with. People don’t usually leave glowing feedback for something as mundane as a filling unless the experience was at least painless in every sense.

If you’re the type who puts off calling until the last minute, the phone line—(636) 978-7816—is there for when you finally cave and decide to schedule that overdue appointment. No lectures, no upselling, just the practical stuff: exams, X-rays, maybe a discussion about implants if you’re missing a tooth. The area’s grown a lot over the years, but the need for straightforward dental work hasn’t changed.

O’Fallon’s spread out enough that “convenient” depends on where you’re starting, but the office sits in a spot that’s central to both the residential pockets and the main drags. For the exact location or to double-check the route, the map lays it out clearly. No surprises, just directions—and, if you’re lucky, a slot open sooner than you’d expect.
