I'm at day 3 and I can't tell you how many people have said "oh you wasted your money that isn't going to work". I was really starting to second guess myself! I only have 12 upper and 7 lower so they weren't too bad but enough to make me smile with my mouth closed. My dentist didn't warn me about these buttons. I have 3- max. left lateral incisor, max. right lateral incisor, and max right canine. I imagine they would be a lot easier to remove without them. On the up-side they're one heck of a diet aid! I haven't been able to sit around snacking while I stress about my husband over seas. Does anyone have any ideas how to round the edges or something? Thanks!
