Extracted wisdom teeth: Preserve or discard???

Wisdom teeth are a valuable asset to the mouth when they are healthy and properly positioned. Often, however, problems develop that require their removal. When the jaw is not large enough to accommodate wisdom teeth, they can become impacted. Wisdom teeth may grow sideways, emerge only part way through the gum or remain trapped beneath the gum and bone. Approximately, 65% of the population has atleast one impacted third molar until 20 years of age.
