Thanks Cathy,

Not sure what to tell you except that David had 3-4 fillings out of the 9 teeth out. Maybe I should have not said they were ALL healthy teeth and confuse you. The fillings were in between healthy teeth. Included in the 9 teeth out, 2 were healthy wisdom teeth. The RO and hospital dentist explained to us the risks of osteonecrosis and the extraction was a way to prevent that. I am not sure if they considered the fact that David took tetracycline when he was a kid and a consequence of that as an adult is that his teeth have been badly stained. Apparently the integrity of the teeth is ok but the "tetracycline generation" was short lived as it was pulled out of the market in the 70s and there is no data on tetracycline treatment and radiotherapy or should I say "I haven't found anything". Is he more at risk? perhaps. I think they didn't take the risk.

At first the RO had recommended all his front teeth be extracted as well because of the high radiation dosage he would use at the front. At the end he has decided on 52Gy and save the front teeth.

I must say that there was not a lot of time to digest all the info. I have done so much reading and I feel I'm constantly on the internet seeking for more data on the SCC of the base of tongue, its cause, treatmentetc...my head is about to explode.

You're right it is a bit late to think about the teeth issue BUT I will make sure that I learn from your input and make sure that I do all my homework b4 the next step. Thanks for your posting.
