worried about brownish line located on my check in my mouth.

I am wondering if anyone has had this before. In inner part of my check closer to my lips is a brownish scar or line. I just noticed it and am kinding of freaking out about it. I rember biting the inside of check several times. Could it be scarring or bruising from that happening?

Usually nothing serious, probably from where your teeth come together.  If it hurts or is irritated have it examined by your dentist.

if you are young, nonsmoker it is probably cheekbiting--- pretty common. but get it checked out by a dentist or oral surgeon to be sure.
