I'm seeing a dentist tomorrow who is insisting on full mouth x-rays as part of the initial consultation. Since I've just gone through 6 weeks of radiation, including head/neck x-rays once a week, I'm wondering what are the risks for ORN or other bad effects from the additional radiation? What is the lifetime max? Where can I find out?

Many thanks,
Riley
