Brush thoroughly with a toothbrush to remove any remaining paste. 2. When applying the strips, air bubbles or saliva may prevent complete adhesion, resulting in uneven whitening. The color will become more uniform with continued use, but it is recommended to wipe your teeth with a tissue before applying the strip to remove moisture and prevent air bubbles. 3. The sheets are for single use only. Please do not reuse them. 【Safe 12-Free Formulation】A 12-free formulation designed with your teeth in mind.
