Hi there! I am 24 years old and I have been suffering from a bump on roof of mouth. It was not there two days before and it has emerged out of no where. Its hampering my mouth movements and I am unable to swallow food properly. I know its due to some kind of an infection which I am not aware of. Let me tell you that I am a non-smoker. I want to know the cure for bump on roof of my mouth?
