Wisdom teeth- doctor said i will have no swelling. so why take them out?

Future problems : Many people just don't have enough room in their jaws for proper erruption or maintenance of wisdom teeth. Sometimes they can form cysts, or damage the other teeth. As a result, we often recommend removing the wisdom teeth before there is pain or swelling. A common time to consider this is around age 15-17, as the roots are not completely formed yet, and the surgery is easiest.

Trust your doctor.: Wisdom teeth, or third molars, can damage the second molars if you do not have enough room for them. Impacted third molars have caused patients in my practice to lose the second molars. The third molars can damage the roots of these second molars which you need to chew correctly. If your dentist advised removal of your wisdom teeth, trust him, or her. It is unwise to ignore this advise.

Not always necessary: Can monitor as an alternative. Impacted wisdom teeth can lead to possible infection, and/or cyst formation in the future.

Prevention: There are many factors that go into the decision as to whether or not it is wise to remove wisdom teeth. If straight and enough room to erupt fully- probably let them. If unlikely they will come in straight and insufficient room, usually best to remove when roots are not fully formed and easily removed, rather than waiting until pain, swelling and difficult to remove. Early intervention is best.
