For a whiter smile, a model is made from an impression of the
upper and lower teeth. Custom trays are made that fit the model
leaving space for the tooth whitening material.
The patient is given the tooth whitening material to be
dispensed in the trays. The trays only cover the teeth and
avoid the gum tissue.
Because the tray fits the teeth precisely, the tooth whitening
material stays where it should be. Even while wearing both trays,
the patient can still function normally making this a very
functional and non-intrusive process.
