Wisdom teeth: interesting facts
It is hard to say why, who, and when they were called "wisdom" teeth. Probably, this is because they erupt after the age of 20, and as people get older, they get wiser. Apparently, this is why they got their name. Anatomically, a wisdom tooth is the third molar. Teeth are divided into incisors, with which we bite, canines, with which we tear the food away, and premolars and molars, with which we grind the food.
