...another thought... have you seen a doctor?

Other things, unrelated, could be causing the sores... like a virus... although I think that would be limited in time to run its course. How long have you been getting the sores?

You could also check with your doctor or local pharmacist on what might help you to be more comfortable in the meantime. My daughter gets mouth sores from time to time, and I know she has found one product over the counter that she swears by... for pain relief and speedy healing. But... I don't know what it was ;(.

Checked with my daughter, and she doesn't remember the name of the product either... but she said they were little press on tabs that you placed over the sores every 8 hours. She even remembered they are gluten free... must have been labeled as such because she is not actually gluten free herself. A pharmacist can probably help you find the product based upon the "press on tabs". I don't imagine there are too many that fit that description.
