A child's first set of teeth, called primary teeth, usually begin
erupting at about 6 months of age, although
teething can begin as early as 3 months of age. Some
babies do not get their first tooth until after 12 months of age. In rare
cases, the first tooth erupts as late as 16 months of age. It is extremely rare
for a baby to have congenitally missing teeth, which is when primary teeth fail
to develop at all.
Sometimes a baby will have a tooth at birth. This tooth usually
does not have a root system and may fall out by itself. If the tooth doesn't fall out, the doctor will check to see if it needs to come out or not.
A baby can sometimes develop an extra primary tooth, most often an
extra third bicuspid or fourth molar. An extra tooth may interfere with
eruption of the permanent one underneath and should be removed.
