Michelle, four years ago I was the first head and neck patient to get IMRT from a very dedicated team. As the first one, I got extra special attention and care. The RO was very experienced so I was not worried. My treatment plan, explained to me in detail, was contained in a notebook three inches thick. There was never any question that I would receive radiation on both sides. The treatment, which included chemo, was not fun, but apparently was effective as I am here and very well today. Furthermore, because of the careful use of IMRT, I have salivary function that approaches pre-treatment levels and is more than adequate. In my case, being first was an advantage, but whether or not you choose that route, I stongly urge you to consider rad to both sides.
