Had my 2nd one out 3 weeks ago (only had bottom 2). First one popped out no bother last November. Second one was a complete farse. Gum had to be cut, took 20 mins to get it out and then took the guy another 20 mins to do the stitches. He right messed them up as my gum has formed into a bit of a weird bump! The stitches were the worst part though, constantly feeling like there was food stuck in my mouth for 2 weeks.
