Not Medical Advice: It is not advisable to leave Crest Whitestrips overnight or while sleeping. Because longer wear time can result in tooth sensitivity and/or gum discomfort.
Crest 3D White Whitestrips are thin, flexible strips that are coated with a tooth whitening gel containing peroxide.
Designed to conform to the shape of your teeth, they work by keeping the whitening gel in place against your teeth to get at stain build-up on and below the tooth's surface.
Please note that Crest 3D White Whitestrips will only whiten natural teeth. The strips will not whiten caps, crowns, veneers, fillings or dentures.
It should not be applied to teeth with braces because Crest 3D White Whitestrips will whiten only the portion of the teeth with which the whitening gel comes in contact.
Because braces cover some areas of the tooth surface only parts of the tooth will whiten, leaving unevenly colored teeth when the braces are removed. In addition, metal in the braces could oxidize and change color.
Your teeth are one of the first things people notice. They are a sign of health as well as confidence. When making a first impression, having teeth that look like you don’t brush them can send a signal that you don’t really care about yourself.
