Nice name, Sarah,Based on your photos, I would highly recommend getting a consultation by a cosmetic dentist for porcelain veneers, if you are trying to have a more noticeable smile.  Veneers can make your teeth bigger, brighter white, and flawless.  In order to help you smile wider, I would also recommend that you consult a qualified speech therapist.  Good luck and I hope this helps.
