These home teeth whitening trays give you a custom fit, just like at the dentist, even though when you order them, they come in one-size-fits-all. The special material conforms to your teeth for more even and effective application of the teeth whitening gel.
They are molded by dipping them in hot water and then placing them in the mouth to form a precise mold of the teeth. For this reason, these whitening trays are referred to as “boil-in-bite” mouth trays. The special blend of polymers has a very low molding temperature so there is no need to use extremely hot boiling water.
Boil-n-bite, or thermo-forming, trays such as these can be a little tricky form. If you don’t follow the instructions very carefully, you could end up with an unusable lump of material.
ATTENTION: One of our most common customer service requests is for replacement trays from people who messed up on their first try. So PLEASE READ THE DIRECTIONS VERY CAREFULLY before attempting to custom-form your trays.
