An aerosol spray-on composition of matter comprising essentially of powdered calcium carbonate in a compatible aerosol propellant such as freon. Additional compatible agents such as an adhesive (benzoin), food-dye, and flavoring (peppermint) may also be added to the powder before suspension in the freon. In use, the powder in suspension is deposited in a thin film on the occluding surfaces of the teeth, the propellant evaporating in the air during propulsion. The broken film indicates the areas of occlusion after the mouth is naturally closed until the teeth meet, and high points in the fitting of dental work.
