[|Human|] I woke up this morning and my gum around one tooth is a dark purple color. It doesnt hurt but feels swollen and a little tender. The discoloration is only on the outer gum the roof of my mouth and the gum surrounding the tooth toward the inside of my mouth is a normal color. When I brush it it does not bleed or anything and I dont think I cut it. I have an appointment with the dentist but not for another 2 days. Do you have any ideas what this could be?
[|AI|]  Hello! Thank you for posting here. This discoloration can be calculus or a piece of food struck which can be causing pain and discomfort. Do not try poking it. Do warm saline water gargle thrice daily. Brush gently. Do not panic. Your dentist will remove it with a scale or a curette. Avoid this area for chewing if possible till you see your dentist. Your dentist will be suggesting you a floss or interdental brush after clinical examination. Take a OTC painkiller if necessary. Regards.
