Scientists may have debunked one of humanity's oldest habits

Scientists have reevaluated the notion that ancient humans regularly picked their teeth, suggesting that grooves on fossilized teeth may be the result of natural wear instead. A study of wild primates supports this theory, offering an alternative explanation for the long-held assumption about human behavior. The research also found that a common modern dental defect is unique to humans, implying that modern lifestyles may be altering the shape of human teeth. This discovery sheds new light on the evolution of human dental health and its potential connection to contemporary habits.
