Wisdom teeth are the third molars,
at the back of the mouth. Sometimes, they can grow into place normally
and never cause a problem. However, often there is not enough room for
them in the mouth and they might crowd other teeth and even push sideways
through the gums.
The signs & symptoms when a wisdom tooth is
problematic







Why do they need to be extracted?
This may be necessary for a few
reasons:
1.
The wisdom tooth may be partially erupted and infected or
decayed.
2. A poorly positioned
wisdom tooth may crowd or damage the tooth in front of it.
3. A cyst may have
formed around an unerupted wisdom tooth. This destroys the bone surrounding the
tooth.
