how often should you use teeth whitening strips

Teeth whitening strips are generally used in an initial treatment course of about 7 to 14 days, with applications typically once daily for 30 minutes to 1 hour per day. After completing a course, you should pause before starting another to avoid overexposure and sensitivity, and you’ll often need a maintenance touch-up 1–2 times per year to keep the whitening effect. Individual products may vary, so always follow the directions on the package or consult your dentist if you have questions about your specific product or tooth sensitivity.
