Many dentists and oral surgeons are advocating the removal of wisdom teeth early because it usually results in less trauma and complications for the patient
As a general rule, the ideal time to extract third molars is when the roots of the teeth are one-third formed, which translates to between the ages of 16 and 20. Our bones are softer and more resilient when we are young, and our bodies simply heal more quickly.
Even when wisdom teeth come in straight, the American Association of Oral and Maxillofacial Surgeons (AAOMS) reported in an October 2011 study that two-thirds of people who let their wisdom teeth come in will eventually experience problems such as infection, cysts, or even decay and damage to adjacent second molars.
