One comment - I don't think it's just dentists that are getting it wrong. My first visit was to my physicians office, and even though I was very worried about the ulcer on my tongue they did bloodwork and gave me diflucan (I had recently had a bowel resection and as a result of all the antibiotics, a yeast infection in my mouth that had previously been treated with the same) .... and said wait and see how it looks in a few weeks. I had a very bad feeling about it, though, and called back within 2 weeks to ask about the best ENT to see - had a hard time getting an appt with one (Most could not see me for at least a month) and finally got in to see one who again did some more lab work and gave me steroids and said let's wait and see the test results and how the steroids work... Finally he agreed it was time to do a biopsy...
