Consult with your dentist and physician before using bleach. All teeth will not whiten the same. Crowns, caps, fillings, dentures, cavities, or bridges will not bleach or change color. Do not use bleach if you are wearing braces. If swelling of the gums, pain, or other questionable symptoms occur while bleaching, stop treatment immediately and see your dentist. Do not use tobacco products or eat while bleaching. Do not use if pregnant or nursing. Do not freeze the material.

Use Crest Whitestrips every six months or as needed to maintain whiteness. If your teeth are significantly discolored, you may need to use 2 boxes of Crest Whitestrips initially to get the desired result. We recommend using a Crest whitening toothpaste to gently polish away surface stains daily.

1) Do NOT brush immediately before use. 2) Open pouch marked Upper and remove. 3) Separate zigzag slit to expose edge. SLOWLY peel strip off backing.
