11 CrownThe crown is the white part of a tooth you see when you look into someone’s mouth.
13 PulpThe pulp is the innnermost layer of a tooth. It contains nerves that feel pain, and blood vessels that carry food to the tooth.
14 DentinThe dentin is the yellow substance that surrounds the pulp. It is harder than bone and makes up most of the tooth.
15 EnamelEnamel is the hard covering on a tooth. It is the hardest tissue in the body and protects a tooth during chewing.
16 CementumThe cementum is about as hard as bone. It surrounds the dentin in the root of the tooth. The cementum and enamel usually meet where the root and crown join.

Now, brush the lumpy surface of your teeth. Be sure to remove any food that may be stuck in the grooves.
