The hardest part of it all is getting used to the big gap in your gums the first few days.
heh, it was the same issue for me. after i was healed enough to eat solids without any real care, i kept mashing down on food back there in the gap. it felt.. odd.
otherwise, my recovery was pretty much a breeze. none were impacted and all 4 came out at the same time. some blood to soak up on the first day, but after that it was just keeping them clean.
