Our teeth whitening trays come in one size that can be customized with hot water and trimmed to fit your mouth.
We have designed our teeth whitening trays to be a one-size-fits-all solution. This means that they are made to fit the mouths of most people. However, we understand that no single product will fit everyone perfectly.
That's why we have made our trays customizable. To fit your trays, simply follow the steps above.
Please note that our teeth whitening trays are made with a thermoplastic material that is designed to be soft and pliable when heated, but it will harden and become firm once it cools.
Based on research, we believe that our one-size-fits-all trays will be a good fit for 90% of people.
However, we acknowledge that no single product will fit all.
