How to
flash.

FLASH isn't suitable for children under 12, during pregnancy or while breastfeeding. Don't use it if you have gum problems or are allergic to any of the ingredients.

Wait two weeks after dental treatment such as crowns, fillings or implants. Don't use the strips while wearing dental braces.

FLASH is designed to be gentle — but if you experience pain or excessive sensitivity, stop using the strips.

No. The strip dissolves completely in under 10 minutes — no trays, no rinsing, nothing to remove.

Use the strips twice daily for 7 days — with a strip for your upper and one for your lower teeth each session, one pack of 28 is exactly one full course. Based on clinical and laboratory testing; individual results may vary.
