5 years ago or so, University of Pennsylvania had a department of Onco-Dentistry, because cancer and the drugs used to treat it usually decimate the teeth and gums of the patients. I don't know if they still do, stopped going there.
My Mrs went from happily going to the dentist every six months for checkups on her outstanding teeth to now five years of root canals, root canal failure(s), multiple opening up of root canals and getting infections out, caps that won't stay on/in, gum infections that nobody can explain. Her teeth and gums have really, really suffered.
Nobody will talk about it because CML is the same as diatetes, just take the pills and everything is cool.
