    • The present invention relates to a tooth whitening strip of material having a shape adapted to fit a user's teeth. Each user has four front teeth, two canine teeth and additional back teeth, such as molars. Each tooth has a front side, a tip, and a back side. The strip of material is of a shape so that the strip will substantially cover the front side of at least the user's front four teeth and two canine teeth. The front sides of additional teeth may be covered. The tooth whitening strip will then fold over the tips and onto the back side of one or more of the front four teeth. However, the strip of material will not cover the tips of the two canine teeth. The strip of material may be of any shape that allows for the canines to protrude. Possible shapes include substantially trapezoidal with or without stair stepped sides or notches, and rectangular with notches, stair stepped sides, or recesses.
