Wisdom teeth are the upper and lower third molars, located at the very back of the mouth. They are called wisdom teeth because usually they come in when a person is between 17 and 21 years or older Old enough to have gained some wisdom. Wisdom teeth that are healthy and properly positioned do not Cause problems.
WHAT CAUSES PROBLEMS WITH WISDOM TEETH?
Wisdom teeth may break partway through your gums, causing a flap of gum tissue to grow over them where food can become trapped and a gum infection can develop. Wisdom teeth can also come in crooked or facing the wrong direction. Or, if your jaw is not large enough to give them room, they may become impacted and unable to break through your gums. You may have trouble properly cleaning around Wisdom teeth because they are so far in the back of your mouth and may be crowded.
Wisdom teeth often cause no symptoms. Symptoms that may mean your wisdom teeth need to be removed Include: .Pain or jaw stiffness near an impacted tooth. .Pain or irritation from a tooth coming in at an awkward angle and rubbing against your cheek, tongue, or top or bottom of the mouth. .An infected swelling in the flap of gum tissue that has formed on top of an impacted tooth that has partially broken through the gum. .Crowding of other teeth. .Tooth decay or gum disease if there's not enough room to properly care for the wisdom tooth and surrounding teeth.
