I think the comment "doesn't look good" coupled with the comment "see us again in 3 months" are indicative of one thing for certain.... you need a new dentist. Just think about it - the two comments are incongruous with each other. If it's something that is bad....why not get off your ass and see that the patient gets a referral to someone for a second opinion and biopsy? This is what gets dentists sued, and what gives patients later staging, which means more morbidity and worse outcomes. Freaking amazing. If they don't know what it is, it is their responsibiity to see that you get in the hands of someone who will.
