The Evolution of Dentistry: A Story of Innovation and Controversy

Dentistry, with a history dating back to the Indus Valley Civilization around 7000 BC, has undergone significant transformations over the centuries. The ancient Egyptians, for example, used ground pumice stone to clean teeth, while the Chinese developed a toothbrush with boar hair bristles around 1200 AD. Today, dentistry is a complex field that encompasses not only routine cleanings and fillings but also advanced procedures like dental implants and orthodontic treatments. However, despite these advancements, issues like access to care, the high cost of dental education, and the debate over the use of amalgam fillings continue to pose challenges. According to the World Health Organization (WHO), approximately 3.5 billion people worldwide suffer from oral diseases, with tooth decay being the most prevalent. The American Dental Association (ADA) reports that the average cost of dental school in the United States is around $250,000, making it one of the most expensive professional degrees to pursue.
