The short answer
Leave whitening strips on only for the duration printed for that specific product, because peroxide strength and strip design vary. Whitening strips hold a peroxide gel against the enamel surface to oxidize some chromogenic molecules. Longer contact can increase gum irritation or tooth sensitivity without making an unsuitable tooth healthy.

What should you do while using whitening strips safely?
Follow the package directions, keep gel off the gums, do not sleep in the strips, and stop if you develop significant irritation or pain. A dentist should check cavities, cracks, gum recession, and restorations before whitening.
When should strip-related pain or gum changes be checked?
Seek dental advice for severe sensitivity, a white or burned-looking gum area, uneven color, or pain that remains after removing the strips.
What should you ask before choosing a whitening strip schedule?
Ask whether your teeth and gums are suitable for whitening, what will happen to fillings or crowns, and which schedule matches the product you have.
