The invention provides a method for the removal or reduction of tooth enamel stains due to fluorosis. The method includes a step of treating a surface of an isolated stained tooth with an abrasive-free solution of hydrochloric acid, having a concentration of from about 6-12N, for a period of time sufficient to significantly reduce staining of the tooth, without removal enamel from the treated surface. Thereafter, any residual acid on the tooth surface is neutralized.
