Abstract: The invention relates to a solution with a concentration of 6N of HCl, citric acid (C6O7H8) and water demineralised by reverse osmosis and bacterially purified by ozonisation and lemon-flavored artificial liquid essence or anise-flavored artificial liquid essence and water demineralised by reverse osmosis and bacterially purified by ozonisation, and to a method for using same to dissolve the brown pigmentation of teeth affected by problems of mottled enamel or chronic endemic dental fluorosis, as well as teeth with white, opaque or yellow stains. The composition is applied to the surface of the part to be treated using a small cotton swab secured with snap clamps, which performs a firm circular rubbing motion until the stains have been removed. Subsequently, a paste comprising calcium hydroxide and water is applied to the part to be treated in order to neutralize any surplus solution and, finally, the mouth is washed with simple water in order to remove any calcium hydroxide residue.
