Best option is go for Invisalign... Its like a disposable contact lenses and even not visible after wearing.... Its quite expensive but the best for esthetic purpose... The other option is crowns and veneers but for this treatment we need to reduce your tooth shape to fix the veneers or crowns... But for Invisalign no reduction of your tooth required, just you have to wear it...
