Gaga's Surgery

I recently found a mass growing in my dogs mouth from the pallet inside her mouth and it wraps around a tooth causing her to bit it every  time she eats. This causes her tons of pain. When going to the doctor today they said she'd need surgery to remove the mass and possible the two teeth its affecting as well. On top of that they need to send the mass out to be tested just to make sure its not cancerous or something else entirely. Anything you can help with would be wonderful. Thank you in advance.
