Step 1
Consult your dentist before using Crest Whitestrips. You should visit your dentist for a complete dental evaluation before using any tooth whitening system (especially if you have multiple fillings or crowns).
-
Step 2
Choose the appropriate whitening system that best suits your needs. Crest has five whitening systems and each one works in a different way. Your five choices includes Classic (provides whiter teeth for 12 months); Premium (whitens teeth for 12 months and provides two times more whitening than Classic); Premium Plus (whitens teeth for 18 months); Renewal (removes up to 20 years of stains from teeth); and the Daily Care (protects teeth from stains and removes surface stains).

Step 3
Purchase the Crest whitening system of your choice. You can buy Crest Whitestrips at a variety of stores such as Wal-Mart, Target and local drugstores.
-
Step 4
Read the directions before using the whitening strips. There are specific instructions on the back of the box that tells you how to use the strips and how many days you need to use them.
-
Step 5
Apply the strips to your teeth. Remove the whitening strips from the box and peel off the backing. Securely apply the strip to your upper row of teeth and align the top of the strip with your gumline. Next, fold the remaining part of the strip behind the teeth. Repeat this same process for your bottom row of teeth. You must wear the strips on your upper and lower teeth for 30 minutes, twice a day (except for the daily care strips which are worn for 5 minutes).
