Glass box is normally only needed for ones that don't do well in office visits and the techs that work with the cat would be injured if they tried to restrain it.
I would suggest anesthesia (make sure they are blood tested to make sure nothing else is wrong prior to surgery) that way if they have to make an extraction of a tooth (mine did) that they are already under to make the process easier and less painful on the cat.
