Hi doctor, I have a grayish patch above my teeth. I have attached some pictures here. Initially, there was a pink spot just above the teeth, and then it turned gray. Under my upper lip, it is dark pink or red. Is this a form of gingivitis? In the morning, I am getting brown saliva. Also, I am getting brownish froth when I brush my teeth. Why?
