Our teeth are made of a hard, bone-like substance.
They are held by small sockets in our upper and lower jawbones called dental alveoli.
Strong fibers anchor them in place.
The upper and lower sets of teeth form two arches..
The teeth on the upper jaw usually erupt 1 to 2 months after the same tooth on the lower jaw.
There are a total of 20 primary teeth.
Usually, about 1 tooth erupts per month once the teeth have started coming in.
There is normally a space between all the baby teeth..
The teeth are connected with the walls of the tooth sockets and anchored in the jaws by the periodontal ligament and the cementum.
The ligament is made up of connective tissue and contains collagen fibers.
These fibers are especially strong so that the teeth can withstand the great pressure put on them while we chew..
The root of the tooth extends down into the jawbone.
The root contains blood vessels and nerves, which supply blood and feeling to the whole tooth.
This area is known as the "pulp" of the tooth.
The jawbone is attached to all of the teeth..
The incisors cut the food, the canines tear the food and the molars and premolars crush the food
The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums
