For best results, thoroughly brush your teeth first. Then, remove the largest strip from the film and apply it to your upper teeth. Fold the remaining part of the strip over the back of your teeth and press firmly. Repeat the same process with the smaller strip on your lower teeth. Leave the gel strips on overnight. In the morning, remove the strips and rinse your mouth thoroughly. Repeat as needed until you achieve the desired result.
