Why Do We Have Baby Teeth?

The video explores the concept of baby teeth, known as deciduous teeth, and their role in human development. Humans, like most mammals, are diaphyodonts, meaning they grow two sets of teeth in their lifetime. The video explains how deciduous teeth are replaced by permanent teeth as we grow, and discusses the evolutionary role of wisdom teeth. It also compares humans to polyphyodonts, species that can regenerate teeth multiple times, and emphasizes the importance of dental care.
