How do you know if you should get your wisdom tooth taken out?

See your dentist: There are multiple reasons for having them removed. Obviously if you are pain then you will automatically seek help. However, there are other reasons to have them removed that can only be determined by exam and x-ray. See your dentist.

Any pain?: Pain is a good indictor. But even in the absence of pain, many wisdom teeth should be removed while young to prevent problems later on. They are much easier to remove on a younger person, and the healing is much better than in older people. See your dentist for advise. Your dentist should be able to evaluate the position and the prognosis of the wisdom teeth via x-rays.
