First off, my snake is about 6 months old and has mouth rot. I think it may have been due to stress, I had to move her from her 30 gallon to a 10 to treat her for mites(mites are gone now and yes I know sounds terrible, got her from a friend who had mites on almost all of his snakes) and I think it may have stressed her out to much. Anyways I am pretty sure she has mouth rot in early stages, her mouth remains slightly open, her mouth looks a tad bit inflamed and is drooling with no pus. Is there a medicine at the pet store I can get for her like an antibiotic? I would like to try a couple things before I go to the vet and get a hefty bill but I will if I need to.

Basically to sum it up, I think my snake has mouth rot what do I do?
