I've noticed that my gums are receding, and I know that that can be a sign of gum disease. However, my gums only bleed when I brush too hard on them and I don't have tooth aches. I searched it and I read that gum receding can also be caused by brushing to harshly. I don't know what is going on. Should I tell my mom about it? Or is it nothing serious and I'm just overreacting.
