I had this done a month or so back, second time around, first time was a breeze, this time was a little bit uncomfortable, initial numbing injection, then s little subsequent pain as she worked on it, but I then asked for another injection and felt nothing at all until much later one it had been done, initial tenderness mainly around the injection site(s), and as it was the bottom jaw it felt a little bruised for a few days. I would say the most notably unpleasant bit (if you can even call it that) was when she put a long thin thing down into my gum, but it was only cos I saw the thing I wouldn't have if I had just closed my eyes and thought if my holidays, the last bit I found the hardest was clenching down on the x-ray panel - my bag reflex goes haywire, but all in all apart from these two VERY minor things, this time round was also a breeze. You will be absolutely fine, and btw I usually hate going to the dentist, hence why I hadn't been for nigh on 8 years and was the main reason I ended up needing this type of dental surgery!!!!!! Always worth going, and I will now. Regularly x
