Hi - hoping someone can help me. I just got veneers done -\- and there's a large white "lesion" or spot right in the middle of the tooth. I went back to the dentist and she had no idea what it was and couldn't polish it off. Does anyone know what this could be? She told me that there are risks in doing it over -\- but I think I should do it over. Could the worst case scenario be that I could lose the tooth there altogether >???
