Dear Linda & Todd,
I would assume that your family dentist is probably apprehensive in providing follow-up care, rather than being apathetic. Most general dentists have very little training in this area, especially if they have been out of school for a long time or dont't take continuing ed courses in this area.
In general, most oral cancer patients are followed by the treating surgeon, oncologist, radiologist, etc. and not their family dentist. However, he or she should be able to provide you with regular oral cancer screenings, fluoride treatments and general dental care. If this is a problem, than I agree with Dragan, find another dentist.
I wish both of you good luck with the treatment and please continue to post.
Jerry
