:: Wisdom Teeth

Wisdom
teeth are the third set of permanent
molars. The first and second molars
are often referred to as the 6 and
12 year molars respectively. Thus,
the terms wisdom teeth and third
molars are synonymous.
The most typical problem with
third molars is that there just
isn’t enough room for them
to erupt into the mouth. This lack
of room causes the impaction of
third molars. Impacted teeth have
many associated potential problems.
Cyst and benign tumor development
are occasional issues associated
with impacted wisdom teeth. These
conditions are usually asymptomatic,
meaning that they are not associated
with pain or other problems that
can be perceived by the patient.
Other common problems with impacted
wisdom teeth are associated with
exposure to the oral environment
through the gum attachment along
the back side of the next tooth,
or second molar. These issues take
the form of infective or inflammatory
conditions that may also be asymptomatic
for many years. Tooth decay can
also develop in the partially exposed
wisdom tooth or in the second molar.
Decay associated with an impacted
wisdom tooth that involves the
second molar may not be restorable
and could result in the premature
loss of the second molar. Early
removal of wisdom teeth can prevent
the development of some of these
problems.
It is best to evaluate wisdom
teeth prior to the development
of the root structure. The roots
of lower wisdom teeth can develop
near the nerve in the lower jaw
that gives the teeth and lip and
chin area feeling. If this nerve
is injured by the proximity of
the tooth root as the wisdom tooth
is removed, paresthesia, or numbness
of the lip and chin can result.
Early removal of wisdom teeth may
prevent the risk of injury to this
nerve.
