Greg - When is your dentist appointment? Sometimes appointments can be moved up if you call and ask. When my son's oral surgeon's office made an apointment for him with the surgeon for a week later, I was such a basket case that my ex-daughter-in-law called for me and moved it up to 3 days later! It's good you are checking out Chapel Hill. If you do a search on OCF main page for Comprehensive Cancer Centers you will find the url for Chapel Hill at - http://cancer.med.unc.edu/ - and many others. The Chapel Hill website can give you lots of information about their cancer center that can help prepare you for making a decision or be able to ask questions of your dentist.
