White sore on hard palate

[jetsetjosh]

Felt a sore in my mouth and thought I might have burned my palate on some hot food. Looked in and saw this white sore on the right side of the palate. Second pic is a day after the first pic, seems to have broken up. Doesn’t hurt as much anymore but still a pain to eat. Is this part of a burn or something else?

Looks like burn or simple trauma. Should heal in a week or less.
