Different Kinds of Teeth:
|
 |
| Your teeth look different from one another because they are
designed to do different things.
The Incisors are the teeth in the very front. They're the sharpest
teeth, built to cut food and shaped to shovel the food inward.
The Canine teeth are in the corners of your mouth. Because they're
meant for grasping and tearing food, they have very long roots.
Premolars are located just behind your Canine teeth. Premolars
have a more flat chewing surface because they're meant for crushing food.
The Molars are the last teeth towards the back of your mouth.
Molars are much bigger than the Premolars and have bigger, flatter chewing
surfaces because their job is to chew and grind the food into smaller
pieces.

Parts of a Tooth:
|
|
| A tooth is basically made up of two parts: the
crown and the root.
The crown is what you see when you smile or open your mouth. It's
the part that sits above your gumline.
The root is below the gumline. It makes up about 2/3rds of the
tooth's total length. |

|
The enamel is the durable, white covering. Enamel
protects the tooth from the wear and tear of chewing. Dentin
supports the enamel on your teeth. It's a yellow bone-like material that's
softer than enamel and carries some of the nerve fibres that tell you when
something is going wrong inside your tooth.
The Pulp is the centre of the tooth. It's a soft tissue that contains
blood and lymph vessels, and nerves. The pulp is how the tooth receives
nourishment and transmits signals to your brain.
