What's actually in an enamel-care toothpaste: reading the Regenerate Advanced Toothpaste label
Upolife editorial — updated 29 October 2026. This article is general information only and is not a substitute for professional dental or medical advice.
Toothpaste labels are dense, and the ingredient names on a tube of Regenerate Enamel Science™ Advanced Toothpaste 75ml can look intimidating at first glance. This guide works through the full ingredient list published by the manufacturer, explains what each component does, and puts the brand's NR-5™ technology claims in context using only manufacturer-sourced and authoritative evidence.
The full ingredient list
According to the manufacturer's product page, the complete ingredient list for Regenerate Enamel Science™ Advanced Toothpaste 75ml is: Glycerin, Calcium Silicate, PEG-8, Hydrated Silica, Trisodium Phosphate, Sodium Phosphate, Aqua, PE-60, Sodium Lauryl Sulfate, Sodium Monofluorophosphate, Aroma/Flavour, Synthetic Fluorphlogopite, Sodium Saccharin, Polyacrylic Acid, Tin Oxide, Limonene, CI 77891. Ingredients are listed in descending order of concentration, so glycerin and the silicate minerals dominate the formula.
The NR-5™ minerals: calcium silicate and sodium phosphate
The manufacturer identifies Calcium Silicate and Sodium Phosphate as the two active minerals behind its proprietary NR-5™ technology. According to Regenerate's technology page, the system is clinically proven to restore lost enamel mineral content by forming hydroxyapatite — the mineral that makes up tooth enamel. An in-vitro (laboratory) study cited by the manufacturer found that 82% of enamel mineral was regenerated after three days' use. The manufacturer is explicit that this figure comes from an in-vitro study, not a clinical trial in human mouths, and that distinction matters when weighing the evidence.
The manufacturer also describes the system as acting on early invisible stages of enamel erosion by restoring mineral content and micro-hardness, and as helping to restore natural whiteness while strengthening teeth against cavities. These are manufacturer-attributed cosmetic and supportive claims; they are reproduced here with that attribution and should not be read as independent clinical endorsements.
Sodium monofluorophosphate: the fluoride source
Sodium Monofluorophosphate is the fluoride-delivering ingredient in this formula. The manufacturer confirms the product contains fluoride. The US National Institute of Dental and Craniofacial Research (NIDCR) explains that fluoride works by strengthening the tooth's hard outer surface — enamel — and helps reverse early decay by replenishing lost minerals. The NIDCR recommends brushing with fluoride toothpaste twice a day as important for preventing cavities.
Hydrated silica: the abrasive
Hydrated Silica is a mild abrasive used in most modern toothpastes to help remove surface stains and plaque during brushing. It appears alongside Tin Oxide, which can also serve a mild polishing function. The manufacturer notes the formula helps restore natural whiteness, which is consistent with the mechanical cleaning action of these abrasive components.
Glycerin: the humectant
Glycerin is the first-listed ingredient, meaning it is present in the highest proportion. It functions as a humectant — retaining moisture in the paste to keep it workable and prevent it drying out. The manufacturer's FAQ notes that the glycerin used in Regenerate™ is vegetable-derived, not from animal sources.
PEG-8 and polyacrylic acid: texture and stability
PEG-8 (polyethylene glycol 8) is a solvent and consistency agent that helps bind the formula's water-soluble and oil-soluble components together. Polyacrylic Acid is a thickener and stabiliser, giving the paste its characteristic gel-like texture and helping to keep the active minerals in suspension throughout the tube's shelf life.
Sodium lauryl sulfate: the foaming agent
Sodium Lauryl Sulfate (SLS) is a surfactant responsible for the lather produced during brushing. It helps distribute the paste across tooth surfaces and assists in lifting debris. Some people with sensitive oral tissue find SLS causes irritation; the manufacturer's warning to stop use in cases of persistent discomfort is relevant here.
Trisodium phosphate and sodium phosphate: pH buffers
Trisodium Phosphate and Sodium Phosphate serve as pH-adjusting agents that help maintain a stable alkaline environment in the paste. This stability is important for preserving the reactivity of the NR-5™ minerals and the fluoride compound.
Synthetic fluorphlogopite: the shimmer
Synthetic Fluorphlogopite is a synthetic mica used to impart a pearlescent or shimmering appearance to the paste. It is a cosmetic ingredient with no known active oral-health function.
Aroma/flavour, sodium saccharin, and limonene
Aroma/Flavour and Sodium Saccharin provide the taste profile — a mild, sweet mint character typical of toothpastes. Limonene is a naturally occurring citrus-derived fragrance component, listed separately as required by EU cosmetics regulation because it is a known potential allergen at higher concentrations.
CI 77891: the colourant
CI 77891 is titanium dioxide, a white pigment that gives the paste its bright white appearance. It has no active dental function.
Aqua and PE-60
Aqua (water) is the primary solvent in the formula. PE-60 is a polyethylene-based wax or binder that contributes to the paste's rheology — how it flows and holds its shape when dispensed.
How to use the toothpaste correctly
The manufacturer directs users to use Regenerate Enamel Science™ Advanced Toothpaste twice daily, in place of your regular toothpaste. The manufacturer's FAQ adds that it should be used at least twice a day, or as recommended by your dentist. This aligns with NIDCR guidance that brushing with fluoride toothpaste twice a day is important for preventing cavities.
Children and fluoride considerations
The manufacturer states that children of 6 years and younger should use a pea-sized amount and minimise swallowing. If children are taking supplements containing fluoride, or if you live in a region with fluoridated water, the manufacturer recommends consulting a dentist or doctor before use. The NIDCR separately advises that fluoride toothpaste should not be used for children younger than age 2 unless advised by a dentist or doctor, and recommends only a pea-sized amount for young children.
Manufacturer warning
The manufacturer states: in case of persistent discomfort or pain please stop using the product, report it through the careline and consult your dentist as this can be the sign of an underlying oral health problem. The manufacturer also notes that some users may experience an unusual warming sensation while brushing, which it describes as nothing to be worried about.
