Hello, Thank you for your inquiry. I understand that you are worried and anxious waiting for test results. You can consider asking more questions about the initial diagnosis. You can always ask for your records and get a second opinion. If I had difficulty with a procedure, I most likely would have referred you to a specialist such as an oral surgeon. Your dentist has an opinion based on your current health and clinical exam. Try your best to be patient and have your diagnosis confirmed. This is the necessary step that will allow you to follow with proper treatment to best treat your confirmed diagnosis. You are right that there are usually multiple possibilities when it comes to a diagnosis. I am glad to answer any additional questions or comment on any other details that you can provide concerning your health.
