I had three wisdom teeth taken out 20 years ago and they healed right up. But then, I was young then too.
But I just went in 2 weeks ago and had them reopened and the cavitations cleaned out. The stitches came out on day 5 and they were all healed over after about a week. I brush right over them now and it's only been 2 weeks. That's why to me it sounds like you're healing awfully slow.
If it was me, I'd go back to the dentist (sorry) and have him check them out just to be sure they're healing right and aren't getting infected or anything. Good luck, I feel for you!!
