I recently had a small bump on the roof of my mouth that was somewhat painfull. I got out a mirror to look at it and thats when I noticed two small black spots on the roof of my mouth. I have tried to search for information on what this could be but can not find anything that mentions black spots. The two spots are not painfull and I honestly do not know how long they have been there. I do not smoke or drink and I am pretty healthy. Any guesses as to what it could be?
