A cosmetic dentist details his experience with this powerful whitening gel that consistently delivers dramatic results
Dr. Kalmanovich is a general, cosmetic, and airway-focused dentist practicing in Laguna Beach and Los Angeles, CA. A diplomate of the American Academy of Dental Sleep Medicine, he treats obstructive sleep apnea with oral appliance therapy, airway evaluations, tongue-tie treatment, and laser-assisted procedures that support better breathing and sleep. He is also the founder of Solid Sleep (solid-sleep.com), which offers science-backed products and education that promote nasal breathing and overall wellness. Known for his compassionate approach and commitment to minimally invasive dentistry, Dr. Kalmanovich combines advanced technology with evidence-based care to deliver comfortable, exceptional results. He earned a BS in Biomedical Engineering from UC Irvine and his DDS from the University of the Pacific Arthur A. Dugoni School of Dentistry.
Before Dr. Alex Kalmanovich met Dr. Rod Kurthy, the dentist who founded KöR Whitening, he tried 4 or 5 different whitening brands at his practice—at one point even experimenting with over-the-counter options. The problem was, none of the products he tried gave him consistent results. Dr. Kalmanovich wanted whitening that was more predictable, with results he could stand behind. He found that with KöR, and now feels much more confident offering whitening to his patients. Here, he details his experience with KöR and the positive impact it’s had on his Laguna Beach, CA, general and cosmetic dental practice.

We also see a decrease in sensitivity compared to other systems. And the seal the trays provide allows the gel to work effectively.
Patients feel like they’re getting a much stronger value with KöR. They’re excited about their results, and often become more interested in other cosmetic or restorative treatments. It opens up conversations about smile improvements and gives patients confidence they'll get the results they want because they’ve seen such good results with a simple whitening procedure.
Whitening That Won’t Let You Down
KöR also helps me give patients a more conservative treatment option, especially if they can't afford a full-mouth treatment case. I can improve their smile without restoring every tooth in their mouth. I can do a combination of whitening and less restorative treatment. I can tell patients, "If we whiten first, we’ll get to a shade you’ll like and maybe need to do less dentistry." That gives me peace of mind.
With KöR, we have a system that's predictable and consistently delivers results that make our patients happy. And that's the ultimate goal. We want to make our patients happy and healthy, and KöR is a big part of that. It’s a product we can rely on.
