An extraction is an oral surgery treatment to remove a tooth and it may be necessary for several reasons. An extraction may be needed if a tooth is beyond the point of repair due to decay or damage.
Wisdom Teeth extractions are one of the more common oral surgeries. Wisdom teeth are the last set of teeth to grow. If they align correctly and the gum tissue is healthy, they may not have to be removed. However, this is not very common. In most cases, wisdom teeth fail to emerge with the correct alignment. They may grow sideways, only partially emerge, and even remain trapped under the gum.
Wisdom teeth that grow improperly can put pressure on other teeth and may affect the natural alignment. Partially erupted teeth can result in a growth in bacteria. Removing wisdom teeth can prevent these issues from developing.
