Should Wisdom Teeth be removed?
If they (wisdom teeth) erupt and align properly, and gum tissue is healthy, wisdom teeth do not have to be removed at all. Unfortunately, this does not generally happen because of crowding and malposition of the erupting wisdom teeth, due to lack of jaw space.
The extraction of wisdom teeth is necessary when they are prevented from properly erupting within the mouth. They may grow sideways, partially emerge from the gum, and even remain trapped beneath the gum and bone. Impacted teeth can take many positions in the bone as they attempt to find a pathway that will allow them to erupt successfully.
These poorly positioned impacted teeth can cause many problems. When they are partially erupted, the opening around the tooth allows bacteria to grow and will eventually cause an infection. The result: swelling, stiffness, pain and illness.
The pressure from the erupting wisdom tooth may move other teeth and disrupt the orthodontic (positioned achieved by your orthodontist) or natural alignment of teeth. Although rare, the most serious problems occur when tumors or cysts form around the impacted wisdom tooth, resulting in the destruction of the jawbone and healthy teeth. Removal of th offending impacted tooth or teeth usually resolves these problems.Early removal is recommended to avoid such future problems and to decrease the surgical risk involved with the procedure. Every year of your life, your bone gets more dense raising the technical aspects of the surgery and increasing the chances of having delayed healing or bone support defects post healing.
