Recently I have noticed a small black mark on the gum line between two teeth in the front of my mouth. I doesn't hurt at all but it does bleed when I brush or floss.
It is located between two teeth that are a slight bit crooked so it can be hard to brush in there. When it bleeds it is only a very small bit, not enough to even taste or anything. It almost looks like a small scab or something. It has been there about 2 months and has not healed or grown. I would just like to know if I should be concerned.
