"We found that odontoblasts, which support the shape of the tooth, are also responsible for sensing cold," said Lennerz.
Teeth that hurt from exposure 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 the study, the team conducted experiments on mice whose molars were drilled under anesthesia.
Mice with dental injuries manifest pain with their behaviour; they drink up to 300 per cent more sugar water than their litter mates without dental injuries,...
