Andrew, that is an interesting comment. I have been getting standard cleanings every 4 to 6 months for 8 years. I have never heard this. It would be interesting to know if this is her/his own opinion or something new in the field. I too would assume it to be out of concern for infection and then Osteoradionecrosis ORN which might follow the infection.

Would you be able to ask this prosthodontist for more detail and references to any study?

Mark, 21 Year survivor, SCC right tonsil, 3 nodes positive, one with extra-capsular spread. I never asked what stage (would have scared me anyway) Right side tonsillectomy, radical neck dissection right side, maximum radiation to both sides, no chemo, no PEG, age 40 when diagnosed.
