From reading these posts, one can relate that physicians or dentists sometimes can miss an oral lesion entirely. Not to be biased but you should have or request your dentist to do a complete oral examination on you. Family physicians are not very familiar with oral lesions because they are not trained in indentifying them in the oral cavity. Don't be afraid to questions if you feel that the answer does not make sense. Seek second opinion or even a third. I have heard some many familiar stories of antibiotics rounds after rounds before cancer is diagnosed. If a doc cannot give you a definitive diagnosis of a lesion, time to get the answer from someone else. DP
