So on my top, front tooth the gums moved up a little and I'm freaking out. They don't hurt, aren't discolored or anything but I'm still worried. I've Googled that this can happen from brushing too hard, so that's what I think the problem is. I just don't want it to get worse and don't know what to do to prevent that, besides brushing softer.

Should I see a dentist? Has this happened to anyone else? Am I over reacting? Pleaseeee leave any advice, experiences, anything.
