Wisdom tooth removal has become a rite of passage for most people. Most mouths cannot comfortably fit this third set of molars. They need to be removed to prevent crowded, crooked teeth. If they are allowed to come in, they may not be able to be cleaned properly, leading to tooth decay and gum disease. When wisdom teeth do not have room to come in, they become impacted in the jaw bone. These can lead to pain and infections. Impacted wisdom teeth that are not removed also increase the risk of certain types of oral cancers.
Not all of the wisdom teeth may need to be removed at the same time. This depends on a number of factors like mouth size and the age of the patient. However, it is usually better to have them removed before they grow longer roots for less complicated removal.
