A dentist in Mundelein who takes the time to get it right
At Lumina Dental, we built our practice around one idea: that great dental care starts with a real relationship. From the moment you walk into our bright, nature-inspired office and someone offers you a coffee, you'll feel the difference. Dr. Sandra Szef leads every exam and every treatment conversation personally, so you always know exactly what's going on, what your options are, and what makes sense for your long-term health. No pressure, no hand-offs to a coordinator, just honest, high-quality care.

Dr. Sandra Szef
Dr. Szef is a compassionate general dentist who earned her Doctor of Dental Medicine degree from the University of Louisville School of Dentistry. Originally from Poland, she immigrated to the U.S. as a teenager and built her career on a simple belief: going to the dentist should feel like catching up with a friend. Known for her gentle touch and special gift for putting anxious patients at ease, she brings advanced training in general, cosmetic, and restorative dentistry to every patient interaction, whether she's treating kids, grandparents, or anyone in between. A firm believer in lifelong learning and a proud member of the American Dental Association, Dr. Szef stays at the forefront of her field to ensure every patient feels heard, cared for, and proud of their smile.
What we do best
Dental implants
Missing a tooth doesn't have to mean living with a gap. Lumina Dental offers the full implant process, from preparation and placement to restoration, so you can get a natural-looking, long-lasting result without bouncing between offices.
Crowns and bridges
Whether you're repairing a damaged tooth or replacing one that's missing, our white zirconia crowns and bridges deliver a strong, beautiful result that blends seamlessly with your smile. Dr. Szef walks you through every step so you know exactly what to expect.
Clear aligners
Straighten your smile on your schedule with SureSmile clear aligners, a discreet, comfortable alternative to traditional braces. Dr. Szef will map out a plan that fits your goals and your life, with no pressure and no guesswork.
What Sets Us Apart
A dental experience designed around you
Lumina Dental was built from the ground up to feel different from every other dental office you've walked into. The technology is more advanced, the conversations are more honest, and the experience from the front door to your follow-up appointment is more personal. Here's what that actually looks like in practice.
Doctor-led care, every time
Dr. Szef personally leads your exam and every treatment discussion, with no hygienists or coordinators in the middle. That direct connection is how trust gets built, and it's what makes patients recommend us to everyone they know.
AI x-rays and CBCT imaging
Lumina Dental uses AI-powered x-ray analysis with Pearl and CBCT imaging to catch what traditional x-rays can miss. Dr. Szef reviews the findings with you directly so you can see exactly what's going on and make informed decisions about your care.
Online scheduling and weekend hours
Life doesn't pause for dental appointments, so we don't make you pause yours. Book online anytime, and take advantage of our Saturday hours when weekday visits just aren't possible.
A modern, nature-inspired office
From the earthy green and brown tones to the marble front counter and warm hospitality touches like coffee and water, our office is designed to feel calm, bright, and genuinely welcoming from the moment you walk in.

Rooted in Mundelein, growing with our community
Proud to support the families who make this community great
At Lumina Dental, community isn't a marketing word; it's the reason we're here. We're proud partners of the D73 school district, the Ice Dogs Hockey Club, and the Mundelein Lions soccer club, because we believe showing up for local kids and families is part of what it means to be a trusted neighbor. When you choose Lumina Dental, you're supporting a practice that's invested in the same community you're raising your family in, and that's something we don't take lightly.
