if you can read medical jargon there is a great site that is a library of veterinary articles called www.ivis.org it's free to sign up
search key words like "overshot jaw" (sounds weird but overshot is the correct term for an under bite it means the lower JAW over shot the skull)
"corrective dentistry" things like that.
Before getting surgery i would go to a few vets that specialize in dentistry. I would think the overshot would have to be very severe and at risk of impairing eating later in life for a vet to recommend surgery.
