MarketplaceInner Mouth SoresPosted on January 2, 2010. I had a small open sores, one on each side of my inner mouth (cheek) for several months. They are located almost at the level of my upper teeth. I thought they were the sores, but they will not disappear. They do not hurt and are not inflated. Ideas? Could the opening of the parotid gland (saliva) glands? They are near the top molars. Maybe they were there all the time and you just noticed them? CommentsThere are no comments.Leave a Comment | Popular My Friends |
