A bump on the roof of the mouth can have a number of causes, including canker sores,mucoceles, fungal infections, or bony growths. The lump may be a small blister, cyst, or hard lump you can feel with your tongue or finger. It may be painless or sore.
Most of the time, a bump on the roof of the mouth is harmless and will go away on its own, with or without treatment. A bump on the roof of the mouth that worsens or doesn’t go away after a few weeks may be a sign of a more serious condition, such as oral cancer, though this is rare.
