Curasept Black Luxury Whitening Toothpaste is designed for whitening teeth in adults and contains several key components like bioactive carbon, substituted hydroxyapatite, chitosan, PVP-hydrogen peroxide complex & carbamide peroxide. Charcoal is sometimes used in toothpaste for its abrasive properties, which can help remove surface stains from teeth. Hydroxyapatite is a naturally occurring mineral in teeth and bones. In toothpaste, it can help strengthen enamel and reduce sensitivity. Peroxidase is an enzyme that can break down certain compounds, including those responsible for tooth discoloration. Carbamide peroxide is a common ingredient in teeth whitening products. It breaks down into hydrogen peroxide, which can whiten teeth by removing stains. PVP (polyvinylpyrrolidone) can help stabilize and deliver hydrogen peroxide, a common whitening agent, to the teeth. Chitosan is a biopolymer derived from chitin and is used in some oral care products for its potential antimicrobial and plaque-reducing properties. The combination of these ingredients suggests that the toothpaste is designed to not only whiten teeth but also strengthen enamel and potentially reduce sensitivity. The use of bioactive charcoal and other whitening agents suggests it may help remove surface stains and whiten teeth over time. The toothbrush contains active charcoal. Additionally, the toothbrush comes with medium hard bristles, which can be effective for cleaning teeth but should be used with care to avoid damaging tooth enamel or gums. The included charcoal toothbrush likely complements the toothpaste by providing additional mechanical cleaning action and potentially aiding in stain removal.
