Finally got a vet, opened her mouth up and he seemed pretty certain it was an infection and not just iritation from rubbing as I had feared. Dosed her with 9ml of baytril, to be repeated every other day for a total of 5 doses, and suggested rinsing her mouth with clorhexidine. hopefully everything shakes out ok. She is a pretty hefty animal, and she is still alert, inquisitive, and moving well so I think things look good.
