The third molars are not able to grow properly in many patients because their mouths and jaws are too small. There is a possibility of overcrowding if these teeth erupt. You will begin to notice that your teeth are shifting or overlapping. A wisdom tooth that emerges after orthodontic treatment can cause the teeth to shift and negate the results. Under your gum line, wisdom teeth are trapped when they are impacted. It is possible to suffer from abscesses and infections from wisdom teeth that are impacted. Dental decay and resorption can be caused by impaction.
