Before you start, dry your teeth thoroughly with a tissue or cloth. This is an important step—saliva on the tooth surface can cause the strips to slide around and reduces how well the whitening gel adheres, which affects results.
Step 1: Apply & Adjust
Peel the strip from its backing and press it onto your front teeth, gel-side down. Fold the edges back along the inside of your teeth and smooth it down so it sits flush against the tooth surface with no air bubbles.
Step 2: Wait 30 Minutes
Leave the strip on for the recommended time (usually around 30 minutes, but check your specific product's instructions). Avoid talking too much or drinking during this time so the strip stays in place.
Step 3: Peel & Admire
Gently peel the strip off and dispose of it. Rinse your mouth with water, and avoid eating or drinking anything with strong color (coffee, wine, etc.) for about 30 minutes afterward to let the whitening effect set.
