Porcelain veneers are the fastest way to straighten teeth without traditional braces.  The only difference is, your natural teeth will have to be prepped to fit the veneers.  This is a permanent solution that many celebrities elect to proceed with because of the great results you can achieve with your smile.  Different than with braces with instant orthodontics "porcelain veneers" you can choose the shade of white you want for your teeth. LM1 is a really white shade that will also look natural.

Instant ortho usually takes place in approx 2 visits, so it should really be named almost instant orthodontics, still much better than waiting 1-3 years to have straight teeth.  The key to great veneers is a great cosmetic dentist with years of experience and continuing education courses relating to aesthetic dentistry.  If you have really bad malocclusion instant ortho may not be the best solution as in some cases too much tooth structure would have to be removed so the veneers could fit properly.
