A process of whitening a tooth provided by the invention includes the steps of providing a delivery device for mechanical dispensing of a predetermined amount of a whitening composition to an applicator tip; dispensing the amount of whitening composition to the applicator tip; applying the amount of whitening composition disposed on the applicator tip to the tooth to be whitened; and allowing the whitening composition to remain in contact with the tooth for a period of time sufficient to whiten the tooth. Optionally, the process further includes the step of exposing the whitening composition to light. A gum or candy for tooth bleaching is detailed along with methods of use. A device adapted to dispense an amount of a dental whitening composition optionally includes a light source for activating the whitener.
