The evolution of tooth enamel has been a mystery for many years, but a new study by researchers at the University of Bristol has shed light on how this hard, protective tissue unfolded over time. The study, published in Nature Communications, shows that the outer layer of enamel evolved first, followed by its inner layers, and that this process was driven by the need for better protection against wear and tear. The findings provide insight into how enamel has been adapted over millions of years to withstand the forces of chewing. Furthermore, the research could help inform the development of new materials for dental protection.
