I had one wisdom tooth erupt, perfectly straight, but lost it b/c it was so difficult to keep clean, floss b/c of the way it was tucked next to the molar. It abcessed, gave me a hell of a toothache and had to be pulled. Even when wisdom teeth come in straight, they can cause problems. Partly, b/c often there is no opposing tooth below or above them. Or they might come in as 'soft' teeth(which I think is what happened with mine) So if the dentist wants to pull it, it might be for a very good reason. Maybe you should talk it over and ask all your questions about the tooth and see what happens.
