Hamsters don't normally need vet check-ups... is there any particular reason why you believe she needs her teeth trimming? If she is struggling to eat then yes she needs to see a vet ASAP, but otherwise, I'd move the vet appointment, or cancel it altogether. The stress a vet appointment can put a hamster through would far outweigh any benefits a check-up might provide; hamster vet appointments are usually only for illness/issues.

Taking her in a secure little carrier with some of her substrate from her cage and some soft nesting material to hide in will help her if she does need to go to the vets. Don't take her nest out though; it's best to leave the nest undisturbed in her cage for her to return to and destress in when she gets back.
