My entire life I've had a hard bump on the roof of my mouth, in the center, just before the hard palate meets the soft palate. It's about even with my 12 year molars. As a kid, I could make brain freezes go away just by touching this bump.
I mentioned this to someone and they swear up and down that they don't have that bump. My mom doesn't think she has one either.
Is this bump normal?
