Tina --
Sounds like you are on the right track, and good for you for pushing for an answer.
On the main part of the OCF site there is a
Dental Lifesavers page -- the foundation has a program to honor dentists who do thorough oral cancer screenings and pick up on conditions at their earliest stages. As we all know, early detection is key. Sounds like your dentist would be a candidate.
I hope all continues well for you!
All the best --
Leslie
