I think my smile is ugly. Its crooked, is there a way to have a better one without surgery? My teeth are straight

Hi, you can transform your smile into one that you love by getting porcelain veneers!
Veneers are thin shells of porcelain that are permanently bonded to the front surface of your teeth. We use them for many types of cosmetic enhancement, including fixing crooked smiles.
Seek out an expert cosmetic dentist in your area who has experience treating cases similar to yours. 

HI:Your smile is not ugly, however with the use of porcelain veneers you can improve the symmetry of your smile.Best,Dr. Maddahi

I don't see the teeth being the issue here. I would find someone who does good work with botox and facial fillers to see if they can improve your smile.

Your teeth are indeed straight and white. However your smile looks crooked because your muscles around the mouth are not working in symmetry. You show more of your teeth on your RHS. Muscle action can be asymmetrical and perfectly natural. Sometimes one can use Botox to even out muscle action and improve the symmetry. I would not recommend surgery.
