Unknown Mouth Sores

[jetsetjosh]

Had these painful sores come up in my mouth a couple weeks ago. Were painful to the point that I couldn’t eat, so I went to take a look. Read that canker sores don’t occur on the hard palate and they didn’t even look like canker sores anyway. What were these things?

I'm not a dentist but I'm pretty sure canker sores can occur anywhere in the mouth.

It looks like gingivostomatitis. It can be treated with oral acyclovir prescribed by your dentist. Canker sores (apthous ulcers) usually occur in non-keratinized (movable) oral tissue unlike in that area which is attached keratinized tissue.

That's almost certainly herpes. Quite typically appear on inner palatal surface of upper molars. Google "palatal herpes" for images.
