Dr. Kourosh Maddahi, DDS
WHEN I STARTED MY FORMAL EDUCATION, I MADE A COMMITMENT TO EXCELLENCE AND I CONTINUE THAT COMMITMENT TODAY WITH EVERY PATIENT I SEE.
A Commitment to Excellence in Every patient Experience
After decades of restoring damaged smiles, many caused by harsh whitening products, abrasive toothpastes, and alcohol-based mouthwashes, I knew the oral-care industry needed a different answer. The products most people use every day were stripping away not just stains, but the beneficial bacteria the mouth depends on to stay healthy.
I had seen it thousands of times: patients using popular products faithfully, doing exactly what they were told, and still developing sensitivity, enamel erosion, and gum issues that brought them to my office. The problem was not their habits. The problem was in their products.
Lumineux was built to change that. Every formula is certified non-toxic, microbiome-safe, and backed by more than 60 clinical and laboratory studies. Because I believe your smile should last a lifetime, and the products you use should help it get there. The high-end technology available today enables me to give patients an amazing, healthy, natural smile without pain or discomfort. The same standard shaped every product in the Lumineux line.
