Why are the edges of my teeth not perfectly smooth?

Question

My teeth are perfectly straight but the bottom (where you chew) are not smooth..is this so you can bite into things better? or whats the reason?

Answer 1

HELLO BELLA,
THE REASON HAS TO DO WITH TOOTH MORPHOLOGY IN THE HUMAN DIET.
WHAT DO I MEAN?
WE ARE NOT LIKE DOGS OR LIONS THAT HAVE CANINE TEETH DESIGNED TO TEAR INTO MEAT AND CRUSH BONE.
HUMAN TEETH ARE ALSO NOT LIKE THOSE OF HERBIVORES, LIKE COWS OR HORSES, THAT HAVE FLAT TEETH MADE TO EAT GRASS AND HAY.
HUMANS ARE OMNIVORES, AND WE EAT A VARIETY OF FOODS. THEREFORE, OUR TEETH HAVE COMBINED MORPHOLOGY.
