A wisdom tooth, in humans, is any of the usual four third molars. Wisdom teeth usually appear between the ages of 16 and 25. Most adults have four wisdom teeth, but it is possible to have fewer (hypodontia), or more, in which case they are called supernumerary teeth. Wisdom teeth commonly affect other teeth as they develop, becoming impacted or "coming in sideways." They are often extracted when this occurs.

Famous quotes containing the words wisdom and/or tooth:
“And wisdom is a butterfly
And not a gloomy bird of prey....”
—William Butler Yeats (18651939)
“With a new familiarity and a flesh-creeping homeliness entirely of this unreal, materialistic world, where all sentiment is coarsely manufactured and advertised in colossal sickly captions, disguised for the sweet tooth of a monstrous baby called the Public, the family as it is, broken up on all hands by the agency of feminist and economic propaganda, reconstitutes itself in the image of the state.”
—Percy Wyndham Lewis (18821957)
