This is a controversial subject. I did not have mine pulled. My dentist checked them out and replaced 3 caps prior to my radiation and chemotherapy. I was also fitted with dental trays and did the fluoride treatment every night. I'm now a 1.5 years out of treatment and haven't had any major problems. I do have to take more care, floss and Gel-Kam every night, because of having so much less saliva.
