Dr. Kourosh Maddahi, DDS

The Beverly Hills Cosmetic Dentist Trusted by the Most-Famous Smiles.

Dr. Kourosh Maddahi has practiced dentistry in Beverly Hills for almost 40 years and is a celebrity dentist featured on Oprah. Throughout his career, he noticed a recurring concern: patients wanted a beautiful smile, but some solutions left them with other oral care problems.

He refused to accept the tradeoffs the category created and so he raised the standard himself, combining the clinical rigor of legacy brands with the better-for-you formulations of cleaner options, because your smile deserves both.

Results, Done Right.

I've spent my career helping patients achieve beautiful smiles, but I've always believed that what you can't see is just as important as what you can. A truly beautiful smile starts with a healthy foundation, and the products we use every day should protect that foundation, not compromise it.

That belief guides everything we create at Lumineux® .

We approach oral care with the same standards I bring to my dental practice: a commitment to proven results, thoughtful ingredients, and long-term oral health. Every formulation is developed with purpose, combining advanced dental science with ingredients selected to work in harmony with your mouth.

Because oral care shouldn't be about choosing between products that work and products you feel good about using. It should be about having confidence that you're doing something good for your smile, today and for years to come.

That's the standard I've spent my career pursuing. And it's the standard behind every Lumineux® product.

WHEN I STARTED MY FORMAL EDUCATION, I MADE A COMMITMENT TO EXCELLENCE AND I CONTINUE THAT COMMITMENT TODAY WITH EVERY PATIENT I SEE.

A Better Experience for Every Smile

In my practice, I use modern dental approach to help patients achieve healthy, natural-looking smiles, with an emphasis on comfort throughout treatment. The experience matters just as much as the outcome, and I want patients to feel confident about the care they receive. Creating Lumineux® was a way to extend that commitment beyond the dental chair and into patients’ everyday oral care. It connects my work as a dentist with a simple goal: helping people care for their smiles between visits through products they can use as part of their daily routine.
