Every time I wake up from the night or a nap, the gum in the front of my back teeth is big with blood, that usually gets released when I brush my teeth. In other words, almost every morning I bleed in between my front teeth. It's really irritating and I'm wondering why it does this. Ps, I got braces a year and a bit ago, and before I got braces this didn't happen. My two front teeth were apart and when they got pushed together it began happening.
