How to draw tooth diagram labeled.

Teeth are structures useful for biting, tearing, chewing and grinding. All mammals have more or less same construction of tooth.A vertical section of a tooth shows three parts viz the crown, the neck and the root. Crown is the part lying above the gum, the neck is the part in level with the gum and the root is the part buried in the sockets of the jaw bones.  The white part of the tooth is known as the enamel. This is the hardest substance present in the body.  The enamel is the non living substance containing calcium salts, and forms an hard biting surface.

Inner to enamel, is another solid tissue, the dentine. Dentine is not as hard as enamel. It contains fine strands of cytoplasm passing through it. Dentine encloses a cavity known as the pulp cavity. This cavity is supplied with blood capillaries and nerves. At the root of the tooth, dentine is covered by a thin layer of bone-like material called cement. The tooth is firmly held in the sockets of the jaw with the help of cement. Now lets start drawing a typical molar tooth.

 Draw outline of tooth as shown.

 Draw the sockets in the bone and the gum region as shown along the tooth.

 Draw the pulp cavity  and root canal with in the tooth.

Give depth to the crown of the tooth by showing flat surface on top.

Put neat dots in dentin region and draw Nerves and blood vessels in the root canal and pulp cavity.

Draw few blocks in bone region to represent the trabiculae in bone.

Label the parts neatly as shown.
