Ideally, when you use over-the-counter whitening products, you want to use them until you've attained the whiteness you're looking for. So you want to use over the counter whitening products for however long it's going to take, and this will vary with how nicely you've made the trays, how strong the material is, and how white you want your teeth to be, and how white your teeth were when you began using the over-the-counter whitening product. So you will use the over the counter whitening product for a longer time if your teeth are dark and you want them to get lighter, or less time if your teeth are already white and you want them to be just a little bit lighter.
