Many people face issues with wisdom teeth due to limited jaw space or improper eruption angles, often requiring extraction. But what purpose do these third molars serve?
Our ancestors depended on wisdom teeth to grind rougher, tougher foods common in prehistoric diets. One leading theory posits they acted as vital 'spare teeth,' stepping in to replace earlier molars lost to injury or decay.
Today, with softer modern diets and progressively smaller jaws shaped by evolution, wisdom teeth are frequently redundant and problematic for millions.
