Hydroxyapatite makes up roughly 97% of your natural tooth enamel. Nano-Hydroxyapatite (n-HAp) is a lab-synthesized version of that same mineral, engineered small enough to bond directly with the microscopic pores and grooves on the tooth surface. It's been studied extensively in toothpaste and gel form, including in clinical trials with young children, and is consistently found well tolerated with a strong safety profile — it's biomimetic, meaning your enamel recognizes it as the same material it's already made of, rather than something foreign being layered on top.
Yes — Noudent is a foaming fluoridated toothpaste with up to 1000 ppm available fluoride, alongside n-HAp and Potassium Nitrate. Fluoride has decades of clinical evidence behind it for strengthening enamel and preventing decay: it helps form fluorapatite on the tooth surface, a mineral more resistant to acid attack than natural hydroxyapatite alone. Pairing it with n-HAp means you get fluoride's long-proven cavity protection working alongside n-HAp's enamel-surface repair, in the same routine.
Sodium Lauryl Sulfate is a foaming agent, not an active ingredient — it doesn't remineralize enamel or relieve sensitivity, it just helps toothpaste lather. It's also known to irritate the mouths of people prone to ulcers or dryness. Noudent uses gentler foaming agents instead (sodium lauroyl sarcosinate, cocamidopropyl betaine), so you still get a proper foaming clean, minus that irritation risk — making it comfortable for daily use across the whole family.
Potassium Nitrate works directly on the nerve inside the tooth. With twice-daily use, potassium ions travel through exposed dentin tubules to calm the nerve's response to hot, cold, sweet, and acidic triggers. It's one of the most well-studied desensitizing ingredients available, with clinical trials showing steady, building relief over consistent use — exactly the kind of dependable, cumulative comfort a daily toothpaste is meant to deliver.
Remineralization and sensitivity relief are usually sold as two separate problems needing two separate products. Noudent's dual-action formula brings both into one tube: n-HAp works on rebuilding the enamel surface, Potassium Nitrate works on calming the nerve underneath it, and fluoride reinforces both. One routine, twice a day, covering the full picture of enamel health.
Apply a pea-sized amount, brush thoroughly for two minutes, morning and night. Consistency is what activates the science here — both the remineralization and the sensitivity relief are designed to build with regular use.
Yes. It's SLS-free, formulated to be gentle on gums and enamel alike, and designed to be safe as part of a daily routine rather than an occasional treatment — the kind of toothpaste your whole household can share.
Yes — Potassium Nitrate is commonly used specifically to manage the sensitivity that whitening treatments can cause, making Noudent a natural pairing for anyone whitening at home or with a dentist.
Keep it in a cool, dry place, away from freezing temperatures, and use within 24 months of manufacture as printed on the batch.
