Utsuka and Jigyasa were thinking about the day they had loads of chocolates. Jigyasa rightly pointed out that eating too much chocolate causes cavities; that’s why we brush our teeth. This made them wonder: “How does brushing help stop cavities?”
Listen to the episode as they both explore teeth up close. They learn about the microbial community living on tooth surfaces, how they function, and what role the microbes and food you eat play in causing cavities.
They also talk with Dr. Karishma Kaushik from Savitribai Phule Pune University (SPPU), a scientist who studies microbes, about how researchers study microbes of teeth in labs. As a clinician turned scientist, Dr. Kaushik shares how her unique background allows her to see her research from a unique perspective.
