What kind of doctor would operate on my mouth but not my teeth?

I have a cyst or something on the inside of my mouth, on the inside of my cheek. Thanks to my insurance plan I can skip the primary care physician and go straight to the specialist to take care of this. What kind of doctor would do this? Would a general practitioner be able to take care of this?|||Usually a ENT does this sort of thing. I had a like a lump on my gum,and my doctor referred me to an Ear,nose and throat doctor.|||An oral surgeon.
