Wisdom
teeth, or third molars, do not always erupt properly when
they decide to make an appearance. It's wise to get an
early opinion from your dentist on getting wisdom teeth
pulled before they become impacted, causing pain, swelling,
infection, caries and gum disease.
Why don't wisdom teeth grow in right?
The shape of the modern human mouth is often too small
to accommodate wisdom teeth which make their first appearance
in young adults 17 to 26. Over the course of time, humans
have developed smaller jaws. When humans learned to harness
fire for cooking foods and developed blade tools to better
process food before consumption, they reduced the need
for strong jaws to chew food. According to studies of
ancient skull specimens, over time, a full set of teeth
in a smaller jaw caused crowding in permanent teeth because
of lack of space.
What does impacted mean?
When wisdom teeth don't have room to grow or they haven't
reached their final position by age 25, they are considered
impacted - no place to go and no plans to grow. Third
molar impaction is the most prevalent medical developmental
disorder. A full set of healthy teeth sometimes doesn't
leave much room for wisdom teeth to grow.
What kind of problems can impacted third molars cause?
Partially erupted wisdom teeth are breeding grounds for
organisms that may cause infection, and cysts and tumors
may grow on a trapped wisdom tooth. Jaw pain and gum disease
may occur. Not all wisdom teeth cause problems, however.
Can't I just use an antibiotic?
Antibiotics only soothe infected wisdom teeth for a short
time. Since people frequently use a wide variety of antibiotics,
the infection may be resistant to such medication and
doesn't solve the real problem: The tooth can't fit in
your mouth.
When is removal necessary?
It isn't wise to wait until wisdom teeth bother you.
Early removal, as advised by your dentist, is generally
recommended to avoid problems, such as an impacted tooth
that destroys the second molar. People younger than 16
heal easier too. At an early age, people should be evaluated
by their dentist who can track third molar development
with the help of X-rays. Second molars should be visible
to lessen the chance of damaging them during surgery.
This occurs at age I I or 12, so wisdom teeth should be
removed when the decision has been made that they cannot
erupt into an acceptable position.
What if I don't have any symptoms?
People with symptoms of impaction, such as pain, swelling
and infection should have their wisdom teeth removed immediately.
However, those with no symptoms can avoid the chance of
ever suffering from impacted wisdom teeth or achieve better
orthodontic treatment results by having them removed.
Asymptornatic impacted wisdom teeth also should be removed
to reduce unexplained pain, accommodate prostehetic appliances,
or avoid cavities, periodontal disease, bone shrinkage
and tumor development.
How is the tooth removed?
Surgery for impacted wisdom teeth consists of removing
gum tissue over the tooth, gently stripping connective
tissue away from the tooth and bone, removing the tooth
and sewing the gum back up.
