This artist’s illustration depicts how, centuries ago, people believed that small worms living within the tooth caused excruciating pain via their cold breath. Proof of tooth worms came when an inflamed tooth was ripped out and small stringy structures -- the nerves and blood vessels -- were visible within the disintegrating pulp and dentin. The tooth worms are actually odontoblasts, cells that form the dentin layer of the tooth, which encases the soft tooth pulp. Bernal et al. demonstrated that the cold sensation in our teeth is mediated by the odontoblast (green structures) and transmitted to the brain via nerves (red), where pain is perceived.
