My gums seem to be coming down further in between my teeth. A few days ago, I noticed a little blood in between my teeth. This morning, I realized it was from my gums. It doesn't hurt. What's going on with this?

As you grow older, gums recede, so what you are seeing is the gum staying the same between the teeth, but the rest is receding. If you have blood when you brush or floss it could be peridontal disease. Get checked by your dentist.
