LO fell and gums look bruised

Casey

So my 11 month old isn't the best at moving around, as in he's really clumsy about it. Today my SO and I were painting/putting up drywall in the next room (we were right by the very big doorway though and we can see EVERYTHING that goes on where the kids play). However, at this moment neither of us were watching and our son fell somehow (he doesn't even walk, we don't know how the heck he fell or from what height). I feel awful as is because I know I should've been watching more closely, but aside from that, his upper gums where his front right tooth hasn't come out yet looks bruised. His front left is just barely poking through the gums and looks fine, but it's that right one where the gums looks dark and bruised. We made an app. with the dentist for noon tomorrow, but I wanted to ask if anyone had this happen to their LO?
