Porcelain veneers can be used to whiten your teeth, among many other benefits.., but keep in mind that the final color you will be achieving, 70% of it comes from your existing tooth color and about 30% comes from Porcelain Dental Veneers.
Having said that, the whiter you can achieve your existing color via teeth bleaching, power or laxer bleaching, the less tooth structure is removed from your precious teeth, to get you the whiter color. That is the reason, why the best cosmetic dentists recommend you first to do bleaching prior to having porcelain veneers,so less tooth structure is removed and your dental veneers last a long time!  After practicing cosmetic and reconstructive dentistry for over 20 years, I have come to the conclusion that the least invasive dentistry, is the BEST Dentistry.Porcelain veneers are also a great way to change the shape of your teeth, to match your lip line, or close the buccal corridors( the space between your teeth and cheek) to give you a fuller, younger looking smile.The alignment of teeth are extremely crucial in designing a spectacular smile, porcelain veneers can correct the alignment of your teeth, to a more pleasing and natural white smile.

When you are seeking to have dental veneers done it is critical that if you are thinking to have your teeth whiter and brighter, do not just do the 6 front teeth, since if you turn your head to the side, your veneers will be sticking out and do show unnatural. It is vital that your dentist evaluates your smile line, and guide you as far as how many veneers is needed to be done! Keep in mind that veneers is a great way to enhance and beautify the individuals smile. Porcelain veneers is an irreversible procedure, know that there is possibility of redoing veneers sometime in the future, hopefully a long long time after they have been placed in your mouth, so that is why it is critical by your cosmetic dentist, to remove the least amount of tooth structure necessary, so the results are long lasting.

Veneers are considered an irreversible cosmetic dental procedure, since minimal tooth structure must be removed in order to substitute it with porcelain.
