Becky,

On the Oral Cancer Foundation Main Site, there is a rather detailed article on trismus. The link is here

https://oralcancerfoundation.org/complications/trismus/

I have so far not read about the experience of anyone who has had success being treated on this forum for trismus. I would strongly recommend that you bring your husband back to the radiation oncologist and ask him/her to refer you to the specialist. If you go to a comprehensive cancer centre, it’s likely that you will be referred to the dental department. My husband’s dentist at the hospital was the one who was most concerned about his jaw opening.
