A delivery device (12) includes a source (16) of pressurized fluid, a nozzle (24, 16) which defines an outlet (22), a pathway (20) which fluidly connects the source of pressurized fluid with the nozzle outlet (22) for delivery of a spray of fluid from the nozzle outlet, and a receptacle (32), which receives a dose of particles (28). The receptacle is positioned in the pathway such that the dose of the particles is carried by the pressurized fluid and through the nozzle outlet, the particles including a tooth whitening agent.
