Extractions, which remove teeth at the root, are a common treatment for a variety of reasons. In children with baby teeth that are slow to fall out, extractions may be necessary to make room for erupting adult teeth or to accommodate orthodontic treatment.
Wisdom teeth are a third set of molars that generally erupt in young adulthood. If not removed, they can often lead to a number of problems like misalignment, headaches and jaw pain. Wisdom teeth are commonly extracted as a preventative measure and, while the procedure itself requires both local anesthesia and often a sedative, the side effects are relatively minimal.
In more serious cases, teeth may require extraction because they are too badly damaged, decayed or diseased to be restored.
