Unstoppable | A Conversation With Change Makers

On today’s episode, we welcome Lucia Smigel, CEO & Co-Founder of Supersmile — the pioneering oral care brand she built alongside her late husband, Dr. Irwin Smigel, known as the “Father of Aesthetic Dentistry.” What began with a clinical breakthrough in tooth bonding evolved into a global brand built on one core belief: the mouth is the gateway to total health. Lucia shares how a personal observation — that traditional toothpaste was too abrasive for bonded teeth — led to the creation of Calprox®, a patented, non-abrasive whitening formula that changed the category. We talk about building a brand from science, leading in a male-dominated industry, stepping fully into CEO after loss, and carrying forward a multi-generational, women-led legacy. A powerful conversation about resilience, innovation, and building something meant to last.   Are you interested in sponsoring and advertising on The Kara Goldin Show, which is now in the Top 1% of Entrepreneur podcasts in the world?
