Aqueous dental preparation containing fluoride ions and having a pH of maximum about 2. The preparation is suitably based on aqueous hydrofluoric acid (HF), particularly with a concentration of 0.5-5% (w/v). The aqueous fluoride-containing solution, particularly dilute hydrofluoric acid, having a pH of maximum about 2 for the treatment of teeth, is employed particularly by direct application, if desired, before or after the application of a solution containing calcium ions to the teeth.
