How many days do i use crest 3d white strips

Use whitening strips only for the course stated on the package, stopping sooner if pain or marked sensitivity develops.

Whitening strips are flexible plastic carriers coated with a peroxide gel. The peroxide enters enamel and dentin and changes some stain molecules, while excess gel can irritate the gingiva or temporarily increase dentin sensitivity.

Check the product leaflet for the wear time, frequency, and maximum course, and apply strips to clean, dry teeth without covering the gums. Do not extend the course, sleep in the strips, or combine them with another peroxide product unless a dental professional has advised it.

Arrange a dental examination if sensitivity persists after stopping, the gums become sore or pale where gel touched them, or one tooth remains dark. Seek urgent care for facial swelling, fever, or trouble swallowing.

Ask whether your enamel, fillings, crowns, or gum margins are suitable for whitening and which schedule fits your product. Also ask how existing restorations may differ in color after natural teeth lighten.
