REGENERATE Enamel Science Serum should be used every month, for three consecutive days, preferably before going to bed. Used in combination with the daily Advanced Toothpaste, the boosting serum actually increases the effectiveness of the toothpaste! This was demonstrated in a 3 day in vitro test, after which enamel micro hardness was measured. A combination of the Advanced Toothpaste and serum lead to a 43% boost in results compared to using just the toothpaste. The serum maximises the power of enamel mineral regeneration, even in interdental spaces that are hard to reach, by acting on early, invisible stages of enamel erosion. With regular use, it has been clinically proven to help regenerate enamel by restoring its mineral content and micro hardness. Thanks to the NR-5 technology and the fluoride in its formulation, the boosting serum helps provide focused protection for your teeth and when combined with the Activator Gel, the NR-5 serum unleashes a concentrated boost of the formula, helping to reverse the early enamel erosion process.
