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 now my work is done, which neither the anger of
Jove, nor fire, nor sword, nor the gnawing tooth of time
shall ever be able to undo.... Wherever Rome’s power
extends over the conquered world, I shall have mention
on men’s lips.”
—Ovid (Publius Ovidius Naso)
