Explanation:
Answer:By the 1700s, dentistry had become a more defined profession. In 1723, Pierre Fauchard, a French surgeon credited as the Father of Modern Dentistry, published his influential book, The Surgeon Dentist, a Treatise on Teeth, which for the first time defined a comprehensive system for caring for and treating teeth. Additionally, Fauchard first introduced the idea of dental fillings and the use of dental prosthesis, and he identified that acids from sugar led to tooth decay.
Dentistry is one of the oldest medical professions, dating back to 7000 B.C. with the Indus Valley Civilization. However, it wasn’t until 5000 B.C. that descriptions related to dentistry and tooth decay were available. At the time, a Sumerian text described tooth worms as causing dental decay, an idea that wasn’t proven false until the 1700s!
In ancient Greece, Hippocrates and Aristotle wrote about dentistry, specifically about treating decaying teeth, but it wasn’t until 1530 that the first book entirely devoted to dentistry—The Little Medicinal Book for All Kinds of Diseases and Infirmities of the Teeth—was published.
