I have a loose molar. I just noticed it 2 weeks ago today. I was experiencing pain due to sinus pressure and was not sure if I was having a real dental problem. Then I noticed that my tooth was a little loose. I went out of town and the sinus problem went away, but my tooth was still loose and it was causing slight pain when I applied pressure to it. Could you tell me what is wrong with this tooth? Why is it all of a sudden loose and pained? When I had my last cleaning in October 2010, this was not a problem. I had my wisdon teeth removed in the summer of 2010 and I just don't know where this cam from.
