In brief: Canker sores

Canker sores, also known as mouth ulcers or mouth blisters, usually heal on its own in about a week or two.
You can use warm salt rinses directly on the sore to alleviate pain. If the sores continue to persist, or are large or painful, visit your dentist. Depending on the nature and severity of the sore, dentists can provide a prescription and antimicrobial mouth rinses to reduce the pain.

In brief: Laser treatment

A painless laser treatment sometimes can keep them from coming back in the same spot.
While they might recur in other spots, over time and with a few treatments, you can significantly reduce them. See an experienced laser dentist.

In brief: Can't

There's no way to prevent them, but you can help mitigate the discomfort by applying some topical medications that you can by at the drug store.
