Hi, I m 18 years old and I ve had this soft, moveable lump on the floor of my mouth behind my front teeth for about 6 months now. I don t believe it has grown in size and I kind of forgot about it until recently and now I ve started worrying about it. I also have this hard lump on the gums at the top of my mouth after a bad ulcer that is now painless. I m a non-smoker, never even smoked a toke of a cigarette in my life, and am not a particularly heavy drinker. I was wondering if there s anyway you could put my mind at rest until I manage to get to the dentist next week. Thanks.
