The invention relates to a system and method for applying a removable dental fragrance device to improve the mouth's scent. The dental fragrance device locates above the gums of a wearer of the device and may comprise a pliable tooth-sized prosthesis which fits over the visible enamel of the tooth like a cap (figure 6), a strip or pad which attaches to the side of the teeth (figure 10), or a clip (figure 15). The device moulds to the enamel in the presence of oral body temperature. The device may be made of semi-permeable resin, gel and/or thermoplastic-type materials, and has a means of containing a fragrant liquid/solid fragrance composition. The present invention relates to disposable delivery systems that are inexpensive and unobtrusive.
