Gum damage?

[gfxrelay]

Hi, I hope someone here can give me some advice. Can someone please explain to me the anatomy of gums in general? Now my problem is as follow a while a go i went to the dentist for a deep cleaning. Since then I have noticed that the gum area between my teeth that used to be pink has turned red. For a lack of a better explanation there is the normal pink layer with the area between my teeth almost seeming like the gum has been bruised or whatever pink was on it scraped of. The gums between my teeth are still in tact, it just looks bruised or scraped. Will this correct it self and if so how long before it gets back to normal. I apologize for my long post. I am freaking out here.
