Abstract: Disclosed is a method of forming a uniform coating onto a tooth surface, which method includes: forming droplets by spraying an orally acceptable coating material through a spray nozzle, wherein the droplets have a volume-averaged droplet size of about 1 μm to about 100 μm, wherein a spray including the droplets travels from a tip of the spray nozzle towards the tooth surface at a spray rate of less than about 10 milliliters/minute and wherein the droplets include a film-forming polymer, a therapeutic agent and/or a cosmetic agent; and depositing the droplets onto the tooth surface to thereby form a uniform coating.
