Dentistry Is One of the Oldest Professions, Dating Back to 7000 B.C.

The next time you avoid visiting the dentist, consider that people have been getting their teeth checked for millennia. Humans have always had dental issues, which is why the history of dentistry can be traced all the way back to 7000 B.C. By 5000 B.C., dentists had written texts about how they believed tooth worms caused dental decay—an idea that wasn’t proven false until the 1700s.
