• Humans get 2 sets of teeth in their life span.
• The first set of teeth is called milk
  teeth/deciduous teeth/primary
• teeth/baby teeth.
• They are 20 in number, 10 in each arch.
• They start their development in the embryonic
  stage and erupt during
• infancy.
• The timing of eruption of teeth may vary from
  child to child.
• But by the time the child is 2 and half years of
  age he/she would have all
• primary teeth (20 in number) in their mouth.
• These teeth are spaced (making more space for
  bigger permanent teeth),
• more white in color (higher enamel content) and
  are small in size (to fit a
• small jaw).

• The child will be able to eat all solid food now.
• Maintaining a good oral hygiene is very important
  as there are permanent teeth underneath
  undergoing development.

• The next set of teeth to erupt in the oral cavity
  is called permanent teeth.
• The permanent tooth that erupts first is the
  first permanent molar at the age of around 6
  years. We totally have 32 permanent teeth.
• Therefore all primary teeth are replaced by
  permanent teeth. In addition, we get 3 permanent
  molars inside quadrant totaling 32 teeth.
