The Maya are probably the best-known of the classical civilizations of Central America. Their civilisation was renowned for its many great achievements before Spain conquered its lands. The Mayas made great strides in the fields of astronomy and mathematics. They built massive pyramids with no modern tools. The Mayas also invented the field of cosmetic dentistry, but it was much different from what you might imagine.
The Mayas often went to their dentists, but not for fillings or to get a new crown put on. They went to have their teeth beautified with gemstones. From what anthropologists have found, Maya citizens from all levels of society had their teeth decorated, regardless of class.
