Thanks so much for your reply Bryanna - I have only just come to look back at this site (I thought I would be emailed if an answer was posted to me}.

The tooth was my second last molar on the bottom. (they labelled it 46???)

The pain that I had seemed to go away after about a week and a half (I think I must have had dry socket). Following this, I ended up with pus oozing out of a soft lumpy area on the extraction site. My dentist put me on Amoxil which made it all look better (less red and less pus) but now I am on my second course and still there is a small amount of pus. I need to go back and I am worried that he did not actually remove the cyst. He told me it would just go away (I can't see or feel the lump where it was anymore but is it possible this is the source of the pus I am seeing?)
