Wisdom Teeth
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
the position of wisdom teeth before they become impacted, causing
pain, swelling, infection, cavities or gum disease.
Why don't wisdom teeth grow in right?
Although we have seen a reduction in the size of the human jaw
during the course of human evolution, we still retain the same number
of teeth. The change in jaw size of modern humans is related to the
discovery and use of fire to prepare food, and the development of
crude tools, such as blades, to process food. As the need for a
powerful jaw vanished, the jaw became smaller and the teeth became
crowded. The space required for the proper growth of wisdom teeth is
no longer available. (The modern human mouth is too small to
accommodate wisdom teeth, which make their appearance in young adults
between the ages of 17-20).
What does "impacted" mean?
When wisdom teeth don't have room to grow 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
erupt.
What kind of problems can impacted third molars cause?
Partially erupted wisdom teeth are breeding grounds for bacteria
and germs and may lead to infection. In addition to jaw pain and gum
disease, which may also develop, impacted third molars are ripe sites
for the growth of tumours and cysts. 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. At an early
age, people should be evaluated by their dentist who can track third
molar development with the help of X-rays. 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. A symptomatic
impacted wisdom teeth also should be removed to reduce the chance of
unexplained pain, cavities, periodontal disease, bone shrinkage and
tumour development.
How is the tooth removed?
Surgery for impacted wisdom teeth consists of removing of the gum
tissue over the tooth, gently stripping connective tissue away from
the tooth and bone, removing the tooth and sewing the gum back up.
