An old-fashioned device or apparatus designed to transmit sound through the teeth or related to dental sound transmission.
From Latin 'dentalis' (dental, relating to teeth) combined with 'phone' (from Greek 'phonē,' meaning sound). A rare historical term from early acoustic technology.
The dentaphone is one of those bizarre Victorian-era inventions that shows people were obsessed with transmitting sound through body parts—there were even bone-conduction hearing devices that worked on similar principles!
