Back to you again, girls, with a question. My gums and teeth are bleeding a lot. There’s even blood left on the bread when I eat. Even when I’m just lying down and not doing anything, there’s always a metallic taste of blood in my mouth. Is this normal? What causes this? Has this happened to any of you? How did you deal with it?
