I recently went to the dentist and she took a full x-ray of my mouth and said there was nothing except my wisdom's and a RC to be done... but I have a tooth on the right side 4 teeth from the back which feels like there is pressure! or when I eat it feels like its moving but when I touch it with my hand or tongue its fine.... and its not sore just annoying.

I was eating a nut bar and i thought this tooth moved side ways but it hadn't and ever since then I've been having this pressure? I've had a lot of issues with my teeth and I hope this is not bad please help! I've also had this sour taste in my mouth before I go to bed, after I've brushed and flossed. I don't know if Im just paranoid?
