I agree with Brian and others here that an ounce of prevention is better than a pound of cure and that education of dentists for early detection of dysplasia would be a key to reduced morbidity and mortality from oral cancer. In my own case, my dental hygienist should have done more about looking for dysplasia. I had oral mucosal problems and brought them to her attention but she said that I should not worry when I should have. I suppose those lobbying for dentists to pay more attention to oral cancer expect that the dentist will guide the hygienist.
On the other hand, we have the problem indicated by Linda the hygienist on this board
