Abstract
A method of whitening teeth that decreases the amount of time that the whitening composition is in contact with the teeth. Specifically, by pretreating the whitening composition with light before contacting the teeth with the whitening composition, the amount of time that the whitening composition needs to be in contact with the teeth can be reduced. In one aspect, the method may include dispensing a tooth whitening composition from a reservoir device into a channel of a mouth tray; activating an electromagnetic radiation source to emit light onto the tooth whitening composition in the channel of the mouth tray for a first period of time to pretreat the tooth whitening composition; and inserting the mouth tray into the oral cavity of the user so that the user's teeth are in contact with the tooth whitening composition in the channel for a second period of time to whiten the teeth.
