Crest

Crest is a United States brand that manufacturers a range of oral and dental healthcare products including toothbrushes, toothpaste, mouthwash, teeth whitening strips, and other products for adults and children.

Most Crest toothpaste products contain sodium fluoride, which is specifically made to protect your teeth against cavities and decay. Other ingredients might include baking soda and whitening ingredients depending on the type of Crest toothpaste you use. If you're unsure about what's in your Crest toothpaste, read the ingredients label carefully or talk with your dentist to find out more.

Do not brush your teeth just before applying Crest White Strips to help them adhere better. Remove the strip from the protective packaging and gently peel it from the liner. Place the strip gel-side down onto your teeth and align it with your gum line, pressing down against your teeth to keep it in place. Fold the remainder of the white strip behind your teeth. Leave the white strips on per the product packaging, however, times may vary between five to 45 minutes as needed and depending on the strength of the product.

The number of times you use Crest white strips daily will depend on the product, the instructions, and the level of whitening you need. Some white strip regimens may require you to apply them daily for one week, while others could last up to a full month.
