General Health Information

One of the Crest Tooth Whitening products is the Crest Night Effects.
This Crest tooth whitening product stays on overnight while you sleep.
This system requires the application of a whitening gel that forms a
coating that stays on the teeth. You must ensure that your teeth are
thoroughly dry before applying the gel so that it will firmly stick to
the teeth. The coating used releases the whitening ingredient to whiten
teeth while you sleep. The coating is simply brushed away in the
morning. In order to maximize the benefit of this system, you are
advised not to miss a treatment. A missed teeth whitening treatment
is made up at the end of the fourteen- day period recommended for the
procedure. The Crest tooth whitening is not intended for use by
children under twelve. Some people may experience tooth sensitivity
and/or gum irritation when using these products. If this happens they
are advised to stop using it for a few days and then resume using it.
If the condition persists, they are advised to discontinue the use of
the product.
