Your story sounds all too familiar. My mom went through the same thing in August 2008 when she went from DENTIST to DENTIST until finally she was referred over to an oral surgeon who determined she had SCC.

A few weeks later she was in the Operating room under-going jaw reconstuction. The mandible from her leg was used to rebuild the jaw. I believe it was about a 10 hour surgery which included six days in the hospital. After a few weeks she began radiation + chemo-therapy. I remember she lost 90% of her hair and had a great deal of difficulty during the chemo.

Surprised your mom was not operated on immediately..

Let me know if you have any questions.
