Thank you PaulB for responding, especially while you are dealing with your own treatment challenges. I will check out these suggestions.

Regarding ENTs, not sure if that is a better option for an extraction, (certainly more experienced with cancer). I think someone once asked on the forum - do ENTs or oral surgeons have more experience with teeth...

A dentist working in a H&N cancer center (we could go to NYC or Boston for a consult) must refer to certain skilled oral surgeons/dentists in the area - how to get that info???

Maybe I need to go back and inquire about oral surgeons at Dana-Farber.
