REGENERATE™ ENAMEL SCIENCE WITH NR-5™ TECHNOLOGY

REGENERATE™ ENAMEL SCIENCE WITH NR-5™ TECHNOLOGY

REGENERATE™ Enamel Science Advanced Toothpaste and Advanced Enamel Serum with breakthrough NR-5™ technology, contains calcium silicate and sodium phosphate salts, which combine to form a fresh supply of enamel minerals.

Clinically proven to restore lost enamel mineral content by forming hydroxyapatite¹, the same mineral as tooth enamel. Enamel is naturally 96% hydroxyapatite.

REGENERATE™ Advanced Toothpaste for twice daily brushing, protects and strengthens against caries, for 3 times stronger teeth².

In an in-vitro study 82% of enamel mineral was regenerated after 3 days’ use of Advanced Toothpaste and Advanced Enamel Serum³.

ADVANCED TOOTHPASTE

FLUORIDE-ONLY TOOTHPASTE

PROVEN TO FORM HYDROXYAPATITE, THE NATURAL MINERAL OF ENAMEL

After twice-daily brushing with Advanced Toothpaste for 4 weeks, scanning electron micrographs showed hydroxyapatite-mineral layers deposited onto the enamel surface. In contrast, when enamel samples were brushed with fluoride-only toothpaste no deposits were observed.

PROVEN IDENTICAL CRYSTAL STRUCTURE AND CHEMICAL COMPOSITION TO ENAMEL

Microscopy and spectroscopy data demonstrated that the new hydroxyapatite has identical crystal structure and chemical composition to the natural enamel mineral.

SUPERIOR PROTECTION AGAINST ENAMEL EROSION

superior-protection-against-enamel-erosion

After 7 days’ application and frequent acid challenges, the combined use of REGENERATE™ Advanced Toothpaste and Advanced Enamel Serum showed two times greater protection from erosion than a fluoride-only toothpaste.
