Refer to the given conversation among three friends.
All of our teeth have same basic structure of root, neck and crown and are made of a tough material called dentine.
If small intestine is removed from the body, digestion of food will take place but absorption of water from food will not occur.
The teeth at the back of jaw are premolars and molars. They both are found in milk teeth set as well as permanent teeth set.
