What are realistic expectations with whitening?
No one can really predict how much lighter your teeth will become. Every case is different. Typically, there is a two-shade improvement as seen on a dentist’s shade guide. The success rate depends upon the type of stain involved and your compliance. Whitening can only provide a shift in color from gray to a lighter shade of gray, for example. Whitening does not lighten artificial materials such as resin, composite, or porcelain.
