• What's the difference between "baby" teeth
and permanent teeth? At between six and
ten months of age, most infants begin to
get their "baby" teeth.
• The Central Incisors (front middle teeth)
usually come in first, and then teeth begin
appearing on either side and work their
way back to the second molars. By the
time a child has reached three years old,
most of the "baby" teeth should be present.
• The process begins to repeat itself when
the child is about seven years old. The
Central Incisors fall out first and are
replaced by permanent teeth. By the age
of 21, most people have all of their
permanent teeth. link

roots lie beneath the surface.
• The roots of your teeth extend
into your gums and beyond into
the jaw bones. Your tooth has
many layers. The outer layer
(enamel) is made of hard
• The next layer (dentin) is
softer. The pulp in the middle of
the tooth contains nerves that
conduct sensations of hot, cold
and pain. The pulp also
contains blood vessels. link
