Teeth that hurt from exposure due to cold can occur for many reasons. Many people have experienced intense pain from cold when they have a hole in a tooth from an untreated cavity, for example. But teeth can also become very sensitive to cold from gum erosion due to aging.
Researchers report in Science Advances that they have uncovered a new function for odontoblasts, the cells that form dentin, the shell beneath the tooth's enamel that encases the soft dental pulp containing nerves and blood vessels.
