if you do not get your wisdom teeth out, they can cause permanent damage. you can get very ill, some have even died. it is nothing to mess around with. they are impacted. try to go to a biologic dentist so you don't get cavitations. http://www.animated-teeth.com/wisdom_teeth/t1_wisdom_tooth.htm
A wisdom tooth is extracted to correct an actual problem or to prevent problems that may come up in the future. Wisdom teeth are extracted for two general reasons: either the wisdom teeth have already become impacted, or the wisdom teeth could potentially become problematic if not extracted. Potential problems caused by the presence of properly grown-in wisdom teeth include infections caused by food particles easily trapped in the jaw area behind the wisdom teeth where regular brushing and flossing is difficult and not effective. Such infections may be frequent, and cause considerable pain and medical danger. Another reason to have a wisdom tooth removed is if the tooth has grown in improperly, causing the tongue to brush up against it. The tongue can tolerate it for a limited time, until it causes a painful sensation, to the point where the sheer pain can numb the tongue affected, and the area around it (part of the lips, and the cheek). The numbness feels similar to the feeling of anesthesia, possibly meaning a nerve can be affected by the wisdom tooth improperly growing in. Also, it is a wise choice to have them removed if undergoing extensive orthodontic work because once the teeth have come in they could inflict some damage on expensive straightening.
