Tooth Whitening Product - Why is Crest Night Effects so effective at tooth whitening? The secret is our patented Liquid Strip Technology coating that stays on your teeth overnight. No other tooth whitening kit, products or systems use it. It whitens teeth at home, while you sleep. Crest Night Effects will give you whiter teeth for at least 6 months. If desired, you can use up to two kits in a row for increased whitening benefit

Q1. How does Crest Night Effects tooth whitening product work?
Crest Night Effects stays on overnight to whiten while you sleep. This is because the Crest Night Effects whitening kit works in two ways:

1) Immediately after you apply Crest Night Effects tooth whitening gel, it forms a LiquidStrip™ coating that stays on your teeth overnight.

2) This coating slowly releases the whitening ingredient to whiten while you sleep. It works to remove stains and loosen stain causing buildup so when you wake up in the morning, you can simply brush the LiquidStrip and stains away.
