Editing Crest Whitestrips (section)

==Description==
[[Crest toothpaste|Crest]] Whitestrips were introduced in 2001.<ref name="LA">[http://landor.com/#!/work/case-studies/crest Landor Associates, 2009, Crest]</ref> The product is used by placing a disposable plastic strip directly onto the teeth that contains an enamel-safe whitening gel. It is reported to be most effective on yellow and heavily stained teeth.<ref name="wp" />

In 2010, the "3D" range of Whitestrips was introduced. The new "Advanced Seal" was a technological advancement from the older Crest Whitestrips. The strips are now non-slip, and also whiten more teeth because each strip is longer. These are available with the strongest retail 3D Advanced Vivid and 3D Professional Effects Whitestrips.{{Citation needed|date=August 2020}}

U.S. dentists also offer a specialized Crest Whitestrips called "Supreme", which is more effective than retail versions due to the higher concentration of [[hydrogen peroxide]].{{Citation needed|date=August 2020}}

Possible side effects from Whitestrips usage include gum irritation and [[white]] spots on the [[teeth]] for a few hours after use. Sensitivity can also temporarily occur. Whitestrips can also have a bleaching effect if they come in contact with [[clothing]] or [[skin]]. Whitestrips are not for use by children under the age of 12, while Crest Whitestrips Supreme should not be used in persons under the age of 18.<ref>{{Cite web|title=Can Whitestrips be Used by Children?|url=https://crest.com/en-us/oral-care-tips/teeth-whitening/can-whitestrips-be-used-children#:~:text=No%20Crest%203D%20White%20Whitestrips%20product%20is%20intended%20for%20use%20in%20children%20under%20the%20age%20of%2012.%20NOTE%3A%20Crest%20Whitestrips%20Supreme%20should%20NOT%20be%20used%20in%20persons%20under%20age%2018).|access-date=2024-06-30|website=crest.com|language=en-US}}</ref> The active ingredient is [[hydrogen peroxide]]. {{Citation needed|date=August 2020}}
