FAQ
Reader questions
Will white strips damage my enamel if I use them too often?
Overuse can weaken enamel and increase sensitivity, so it is important to follow recommended intervals and avoid longer application times than instructed.
Can I use white strips on crowns, veneers, or fillings?
These products only lighten natural tooth structure, so restorations will not change shade and may stand out more after whitening.
Why do my teeth feel sensitive right after using white strips?
Peroxide temporarily opens microscopic pores in enamel, which can cause short term sensitivity that usually fades after treatment ends.
How long will the results last once I finish a course of white strips?
With careful maintenance and limited staining habits, many people see results for six to twelve months before considering a touch up.
