Thanks for your post Vin and I hope your spouse is doing well.
What will it take some dentists before they know this can be deadly??? It has to hit them personally before they will care. It is really sad if they get nothing out of it (no extra pay or incentives) then to them an oral cancer screening is just a waste of their time.
Pity on them. I'm sorry your spouse had the same useless 2 visits to the dentists as my husband did.
