Brushing your teeth thoroughly with the preparation once a week. Just use elmex dental gel using a regular toothbrush for a period of 2-3 minutes, rinse normally. The total time of application (brushing and residence time) should not exceed five minutes.

The outer 50-100 mkm of the surface of freshly extracted human incisors was removed by grinding and polishing, thus removing not only the pellicle from the surface but also the outer mineral layer, which in general shows the greatest variation in chemical constituents. Amine fluoride 297 (AmF 297) were dissolved in distilled water. After adsorption of aminefluorides on the enamel for 2 min at a volume to area ratio of 25 cm3/cm2, the enamel surfaces were rinsed with distilled water and allowed to dry for several hours at room temperature in an enclosed chamber. Subsequently adsorbed layer thicknesses were determined by ellipsometry, and surface free energies were calculated from contact angle data.
