I am a dentist and the founder of dende, a dental clinic specializing in teeth whitening. Through daily clinical practice, I see firsthand how difficult it is for patients to maintain consistent, effective plaque control with conventional toothbrushing, and how this affects both oral health and whitening results. I am now developing a brush-free oral cleaning system that combines suction-based cleaning with QLF-guided plaque targeting. I bring clinical insight into patient needs and oral hygiene behavior, and I am looking for technical partners to turn this concept into a working prototype and, ultimately, a consumer product.
