Wisdom teeth are the third and final set of molars that start to form in your late teens to early twenties. Sometimes these teeth can be a valuable asset to the mouth when they grow properly aligned. Unfortunately, these teeth are often misaligned and require removal. When wisdom teeth are misaligned, they may position themselves horizontally, be angled toward or away from the second molars, or be angled inward or outward. Poor alignment of wisdom teeth can crowd or damage adjacent teeth, the jawbone, or nerves.
