Joe, I've had four during the last several years.
The procedures done on me were done using Novocaine...which deadened my mouth to the point where he could have cut my tongue out without me protesting.
Keeping your mouth open wide for the required time can be arduous, but it can be handled. Once the nerve is killed (which is the root canal) there is no pain there at all...and a post is inserted to anchor a cap.
Good you are going to a specialist. Regular doctors do root canals, but a specialist is a better bet.
Shouldn't be a hygienist involved...and no tip would normally be required.
The thing will most likely be done in two stage...with casts being made before the root canal...then the root canal. Then you come back in a week or so to have the cap put on.
Mine cost about $900 for the root canal...and another $800 for the cap.
