Researchers have known for years that cold tooth pain arises from damage to the tooth's protective outer layer. But exactly how the message goes from the outside of the tooth to the nerves within it has been a bit of a cold case. 

But this week biologists published a study in Science Advances identifying a potential reason why: a protein embedded on the surface of cells inside the teeth. Scientists think the discovery could potentially lead to the development of treatments for tooth pain.
