TEETH The human teeth are calcified,
bone-like structures embedded in
the alveolar processes of the
maxilla above, and the mandible
below. There are 32 permanent
teeth in the adult human, and
they function to tear and break
down food in a process known as
The hardened alveolar processes
of the maxilla and the mandible
form the sockets that hold 16
teeth each. Each row of 16 teeth
is made up of 2 incisor, 1
canine, 2 premolar and 3 molar
teeth on each side of the face.
Anterior View Teeth are made up of several
connective tissues of varying
hardness, and are supplied by
nerves and vessels. The outermost
layer of the teeth is the enamel,
which is highly mineralized with
hydroxyapatite, and is the
hardest substance in the human
Posterior View Deep to the enamel is the more
bone-like substance called the
dentin. Dentin makes up the bulk
of the tooth and it is calcified
to support the structure of the
Lateral View Permeating the dentin are
microscopic channels called
dentinal tubules that extend from
the pulp cavity throughout the
dentin and supply the tooth with
The innermost part of the tooth
is a nerve and blood vessel
filled cavity called the pulp
cavity. The pulp cavity is made
up of odontoblasts that produce
dentin, and the nerves and
vessels that occupy a 'cell free
zone' in the cavity. R. Lateral View
