question: My friend has a problem - he thinks he has gum disease, and he's going to the Dentists' office ASAP. He wants to know what he has before though; here is the message he sent me.I think I'm going to loss my tooth. My gum has to be infected ( I didn't get it checked ) but there is a lump in the inside and I woke up fine and went to brush my teeth and there was pus on my tooth and my tooth is loose. I think I have gum disease.
