A dental whitening kit is used to apply a tooth whitening composition to a user's teeth. The kit includes a mouthpiece having a cavity for receiving the teeth and a separate and distinct thin sheet composed of a heat and pressure deformable plastic. The sheet is heated to a temperature and for a duration such that the sheet is sufficiently pliable to form a dental impression therein. The sheet is disposed over the cavity such that the user bites into the sheet and the cavity to form a tray having an impression of the user's teeth. The tray and the mouthpiece are disengaged from the teeth. The tray is then separated from the cavity of the mouthpiece and receives the tooth whitening composition. The user re-engages into the tray with the teeth to apply the whitening composition to the teeth.
