My gums at the top.of my front teeth not my first 2 but just next to them has looked swollen for a few months it looks a bit cracked! ! There's a tiny part what's really sore when I brush it but other than that no pain really. .. I'm sure it's sertraline what's causing it but I know the doctor will say it's not. Has anyone had this and will it go down?? I'm scared my teeth are guna fall out!
