A device is provided which includes a cavity containing teeth whitening gel. The device can be attached to a tooth so that the tooth lies inside the cavity and the teeth whitening gel comes in contact with the tooth. The device may includes a plurality of sections, each of which may be designed to attach onto a corresponding single tooth. Each of the plurality of sections may have a width and a length which are about the same as the width and the length, respectively, of its corresponding single tooth. The device can be compressed, expanded, or flexed, so that the device can fit different sets of teeth for different individuals. The apparatus may further include a protective covering for sealing the gel inside the cavity.
