As with any beauty or health product, knowing how to properly use and apply it will give you the best results. If you've never used Crest Whitestrips before, they're very easy to use, but here's a quick overview of what to expect and how to use them.

Step 1: Step 1: Prep Your Teeth

Dry your teeth before opening and applying the strips, but DON'T brush. This helps avoid any irritation from your toothpaste when the strips containing the whitening gel is applied.

Step 2: Step 2: Open and Apply

Open 1 packet of the strips and remove from the plastic backing. The side that was attached to the plastic contains the whitening gel. Apply the gel side of the longer strip to your top teeth just along the gum line. Press and seal the strip onto your teeth and fold the rest of the strip behind your teeth. Repeat with the shorter strip for your lower teeth. Leave on for advised application time.

Step 3: Step 3: Remove Strips

Remove the strips and discard. Brush lightly after to remove the remaining whitening gel from your teeth. For more help and information or to purchase whitening strips, go to www.caliwhite.co.uk
