The oral microbiome - the unique cohort of bacteria that live in our mouths - don't just cause cavities and canker sores. Diabetes, obesity, Alzheimers Disease, and many more conditions beyond the mouth and even the digestive system have been found to be related to the balance of good and bad bugs coating our teeth, tongue, and cheeks. What if a combination of dental care, genomics, custom probiotic toothpaste, and even light could help optimize it? The Biome Brush artifact explores the science and user habits that could ensue.
