when will the teeth whitening wear off?

Doesn't "wear off": Professional teeth whitening works by "bleaching" the colors trapped within the tubular structure of enamel/dentin. That's why it won't change the intrinsic color of fillings or porcelain. The teeth can discolor again if the discoloring agents (tobacco, coffee, tea, red wine, etc.) are not decreased or eliminated. How long? = quantity+frequency. Once lighter though, they re-brightens quickly.

Please note: whitening can remove and/ or bleach plaque--but it will be back in 24 hours without thorough flossing and brushing.

It varies: It varies from person to person. I see some people that do not whiten often and the teeth still look good. And others require touch ups. All teeth naturally get darker with age and habits.

Several causes: The technical term is atrophic glossitis or bald tongue. It is caused by the absence of papilla which are the small bumps that cover the tongue. Diabetes, anemia, celiac disease and certain nutritional deficiencies are common causes as are anti-cancer drugs. It can also be caused by an inherited nerve disorder called riley-day syndrome.
