As long as you are not medically compromised, removal of wisdom teeth is generally safe.
To me your are asking the wrong question. Nothing you related in your history or symptoms would lead me to think that at your age the wisdom teeth would suddenly be responsible for your pain. It's possible but I suspect other issues. Since I don't have all the facts and can't exam you, my suggestion would be to see an orofacial/tmj specialist to determine the true cause of your pain(that's what we do). YOur dentist is correct about the sensitivity, and the root canal procedure should have eliminated the pain if its origin was that tooth. This just doesn't add up. You should be able to handle the oral surgery if you are in good health, but truthfully I would have the pain diagnosed before doing that, and then it may be elective if it is not the cause of your current symptoms.

Thank you. You are right but I am desperate for relief from the pain. This morning I woke up with a horrible earache, with loud noises in my ear. Thought I had sinus problems before and my MD gave me a 10 day course of Keflex, which I am on my last day of. The headaches have been relentless, and I never suffered from them before. I just figured it was my wisdom teeth because the one that came down just broke thru my gums about 5 months ago. Sinus x-ray was normal. Thanks for you advice. I have Kaiser for only a few more weeks, so we will see how this progresses Thanks again!.
