How long should i keep crest white strips on

Keep Crest whitening strips on only for the wear time printed for your exact product, because formulations and instructions differ.

The strip is a flexible carrier that holds peroxide gel against the labial surfaces of the teeth. Its label determines the contact time and schedule; leaving it on longer does not make it an appropriate substitute for a dental whitening plan.

Read the complete package instructions, apply the strip to clean, dry front teeth without pressing gel into the gum margin, and remove it at the stated time. Stop and rinse if marked irritation or strong sensitivity develops, and avoid swallowing the gel.

Ask a dentist before use if you have cavities, gum recession, exposed roots, cracks, untreated gum disease, or extensive restorations. Seek care for persistent pain, ulceration, swelling, or a dark tooth.

Ask which wear time applies to the exact box, whether your teeth and gums are suitable, and how to manage sensitivity. Ask whether restorations will remain a different shade after whitening.
