Empty Space on the Sides of My Smile
I am so glad you asked that question. The empty space is called a Deficient "Buccal Corridor". It does make the smile look esthetically incomplete. From your picture, you also appear to have protruded, large incisors. The esthetics of your smile can be improved with orthodontics to widen the arch and align the teeth for an esthetic smile consistent with your face. For someone else, Porcelain Veneers would be a better solution.
