Abstract
A tooth whitening apparatus which includes a container having a cavity containing a tooth whitening composition and an applicator assembly which includes a cap, a rod member coupled to the cap and protruding from a bottom end of the cap and having a longitudinal axis, an outer surface, and a distal portion, and an applicator tip coupled to the distal portion of the rod member. The applicator assembly is alterable between: (1) an attached state whereby the cavity of the container is sealed; and (2) a detached state whereby the applicator assembly is separated from the container to apply the tooth whitening composition onto a user's teeth. The outer surface of the rod member includes at least one vent groove that is elongated in a direction of the longitudinal axis to reduce a pressure in the cavity of the container when altering the applicator assembly into the attached state.
