Bill:
Yes, my RO explained all of the issues/concerns and sent me to my dentist for x-rays, a thorough cleaning, a checkup, flouride treatments to use during my TX period, etc. He also instructed me on what to let them know about my future treatments and that if there were any questions to page him and he would respond while I was there for my appointment to answer questions.
It was one of those "moments of fate" when my regular dentist was on vacation and due to needing this completed immediately I was sent to another location in the metro area. Once in the office, the attending dentist knew so much about what I was going through (and the journey I was embarking on) as her uncle had been an oral cancer patient while she was in dental school. She was well versed and very, very helpful making me feel very positive about going forward with TX and maintaining healthy teeth. I went back post TX and she had relocated back to her hometown which is a real bummer!! Both pre and post TX my RO has been all over the dental thing (My ENT has as well) both explaining as well as following up on my dental care and what I need to do in order to keep my teeth healthy. My speech therapist thought that a missing tooth on the side of my surgery (Lost it the spring prior to getting sick, probably due to the tumor, but we didn't realize it at the time), might help my chewing and swallowing if it was bridged. My RO has been involved in this process to the point of phone conversations with the dentist regarding exactly what he wants to do (Drilling, setting, bridging, etc).
Maybe I'm just fortunate with regards to my medical team being so involved with the dental aspect but it has truly been helpful to me. Both my RO & ENT look at my teeth and comment on them during every checkup!! Anyone reading this that is starting their treatments should be asking questions if they aren't given any information or insight on dental care and treatment. I hope this is what you were looking for and helps.

Steve
