How Do I Make my Two Front Teeth Look Less 'Goofy'? (photo)

My teeth have always made me very self conscious - they are too big. I have had invasilign braces and now wear a fixed metal retainer. I recently went to a cosmetic dentist but she told me my teeth were absolutely fine - that she would never consider veneers (I don't want them!) and she would not want to file them down. However, she did suggest rounding off the edges - which she did and now I feel even more self concious than before as the front teeth now look even more prominent. Please Help!
