I am using the "brilliant" tooth whitening kit right now and was just wondering if the results are permanent or not?

Bleaching teeth: Nothing in this world is permanent. Foods and drinks will continue to stain teeth. Avoiding coffee, tea, blueberrys, cherries, colas, curry, etc. Will help to keep your teeth brighter for longer.

Not: Your teeth will continue to stain from the foods you eat after the whitening process.

Tooth whitening: As with all whitening products, the results are not permanent. If you don't periodically do a touch up whitening, your teeth will darken/stain again.
