| 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 correctly?
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.
