Why get my
wisdom teeth out?
Wisdom
teeth, especially those that are stuck down in the bone or gums
(impacted), can cause some major complications. The typical
symptoms are usually just soreness in the area as the tooth
comes in. But a majority of wisdom teeth don't come into the
mouth nice and straight. Most people have at least one wisdom
tooth that is heading towards problems such as:

Infection
A tooth that is stuck or
impacted in the bone can leave a space under the gums and
into the bone where bacteria, food,
and other irritants can get lodged. When this happens,
an
infection grows in the area. It can be very painful and in some
cases can lead to infections of the face and throat. In extreme
cases this can result in major surgery or death.

Crowding and damage to other
teeth
Wisdom teeth that are coming
into the mouth at the wrong angle will tend to lean against the
tooth in front of it. This added pressure will push the other
teeth forward in the mouth and usually shows up as crowding of
the bottom front teeth.
If the wisdom teeth get stuck up
under the tooth in front, it will slowly damage the roots of
that tooth to the extent where we sometimes need to take both
teeth out due to the extent of the damage.
Cyst
Formation
A
cyst is similar to a tumor that forms in the bone around an
impacted wisdom tooth. The cyst destroys the bone around the
tooth and can sometimes continue to grow and destroy a large
portion of the jaw. If left too long, these cysts may require
major surgery and removal of a portion of the lower jaw.
My wisdom teeth came in straight,
why should I remove them?
A recent study finds that third
molars which have broken through the tissue and erupted into the
mouth in a normal, upright position may be as prone to disease
as those third molars that remain impacted.
I had the wisdom teeth on my
left side extracted because they were impacted. The teeth on my
right side came in straight so we allowed them to stay. Sure
enough, later in life I started having problems back there
because I was having a tough time brushing way back there.
Eventually my tooth broke in half and after a couple days of
pain, I had it removed. Sometimes its best not to wait for
something horrible to happen.
Must the Tooth Come Out if it Hasn't Caused Any Problems Yet?
Not all problems related to
third molars are painful or visible. Damage can occur without
your being aware of it. As wisdom teeth grow, their roots become
longer, the teeth become more difficult to remove and
complications become more likely. In addition, impacted wisdom
teeth are more likely to cause problems as patients age.
No
one can predict when third molar complications will occur, but
when they do, the circumstances can be much more painful and the
teeth more difficult to treat. It is estimated that about 85% of
third molars will eventually need to be removed.
When Should I Have My Wisdom
Teeth Removed?
Wisdom Teeth Growth by Age

14 years 17
years 25 years
Wisdom teeth are easier to remove when the patient is younger,
since their roots are not completely formed, the surrounding
bone is softer, and there is less chance of damaging nearby
nerves or other structures. Removal of wisdom teeth at a later
age becomes more complicated as the roots have fully developed
(may involve the nerve), and the jawbone is denser.
It
isn't wise to wait until your wisdom teeth start to bother you.
In general, earlier removal of wisdom teeth results in a less
complicated healing process. We strongly recommend that wisdom
teeth be removed by the time the patient is a young adult in
order to prevent future problems and to ensure optimal healing.
The research has found that older patients may be at greater
risk for disease, including periodontitis, in the tissues
surrounding the third molars and adjacent teeth.
