Why do we have wisdom teeth? I hear that itís a remnant of evolution. Is that correct?
Victoria: Yes, as far as I understand it, thatís the case. Our ancestors needed wisdom teeth. They are, as many people will know through suffering, teeth that come through much later (between the ages of 18 and 25). Thatís why theyíre called wisdom teeth. Youíre older and wiser when you get them. Allegedly. Our ancestors, when they used to eat raw meat and grub around and eat lots of roughage would grind down their existing teeth. They had to use very powerful jaws and chew a lot more. They then had a spare set of teeth that came in later on.
