Meet your new favorite way to brush. Nudge brings 10% nano-hydroxyapatite, the same type of calcium-phosphate mineral that makes up tooth enamel, into a carefully considered brushing formula.
Think that just-brushed smoothness you keep noticing. A fresh, polished finish. Enamel-conscious mineral care and a gentle, low-foam formula that makes the twice-daily ritual something to look forward to. Thoughtful ingredients, serious science, and four flavors worth coming back for.
Your enamel is made primarily of hydroxyapatite. Nudge delivers 10% nano-hydroxyapatite in a mineral-first formula inspired by research on enamel remineralization and early mineral repair. It is an intentional upgrade to your everyday brush.
Hot coffee, a cold drink, or an uncomfortable brushing experience can make you pay attention to your teeth. Hydroxyapatite is studied for sensitivity comfort and its interaction with exposed dentin surfaces, giving you one more reason to choose a mineral-focused routine.
Thoughtfully balanced polishing ingredients help remove everyday surface buildup. The reward is immediate: a refreshed mouth and teeth that feel beautifully clean after brushing.
Nudge is SLS-free and uses a coconut-derived cleanser. Enjoy a satisfying clean with a gentler-feeling, lighter foam and a smooth rinse, morning and night.
Refreshing Natural Mint. Bright Orange. Juicy Watermelon. Warm Cinnamon & Clove. A daily essential should be something you actually look forward to using.
10% nHA by weight. Rod-shaped, uncoated particles. Fluoride-free, SLS-free and independently screened for heavy metals. Meaningful details, clearly disclosed.
Tooth enamel is composed primarily of hydroxyapatite. That's why nano-hydroxyapatite has become such an interesting ingredient in modern oral care: it provides calcium-phosphate particles with a close chemical relationship to the mineral already present in your teeth.
Research has investigated hydroxyapatite toothpaste for remineralization, protection against early enamel mineral loss and support for tooth-sensitivity comfort. Nudge makes that science part of a simple routine you can enjoy twice a day.
The details behind your daily brush
10 grams of nano-hydroxyapatite per 100 grams of finished toothpaste—not 10% of a diluted premix.
A defined particle specification, rather than a generic ingredient description.
An SLS-free cleanser, mineral polishing ingredients and flavors designed to make your daily routine feel good.
Your enamel works hard every day. Food, drinks and bacterial acids continually influence the balance between mineral loss and remineralization at the tooth surface.
Hydroxyapatite particles are studied for how they interact with enamel and dentin, including their ability to deposit on tooth surfaces and support mineral repair in early lesions. Research on hydroxyapatite-containing toothpastes has also explored how they compare with conventional toothpaste approaches in clinical use.
Nudge brings this science into a fluoride-free, SLS-free paste that feels good to use. Our 10% rod-shaped nHA is uncoated and selected with attention to its physical characteristics. Great oral care should be both sophisticated in its formulation and effortless in your routine.
Know the concentration. Know the shape. Know what you're brushing with. Nudge is built for people who care about the ingredients they use every day, and want something more substantial than a beautiful box.

The details you deserve before choosing your everyday toothpaste.
Nano-hydroxyapatite toothpaste contains fine particles of hydroxyapatite, a calcium-phosphate mineral closely related to the mineral that forms natural tooth enamel. This ingredient has been studied for remineralization of early enamel changes, interaction with tooth surfaces and sensitivity comfort.
Nudge is formulated with 10% nano-hydroxyapatite by weight in the finished paste. That means 10 grams of nHA per 100 grams of toothpaste. Concentration is one detail we think customers should be able to verify; clinical research has investigated hydroxyapatite-containing toothpastes at various concentrations, including 10%.
Natural enamel contains organized hydroxyapatite crystals, and the physical characteristics of added hydroxyapatite are an important part of formulation science. Nudge uses rod-shaped, uncoated nHA and identifies the particle form rather than describing the ingredient only by name.
Researchers have explored how hydroxyapatite-containing formulations interact with enamel and dentin surfaces and support mineral deposition in early lesions. Its calcium-phosphate composition makes hydroxyapatite particularly relevant to enamel-focused brushing routines. You can read the linked clinical research above.
Hydroxyapatite toothpastes have been studied for dentin hypersensitivity, including the potential to cover exposed dentin and interact with microscopic tubules. If sensitivity is persistent or severe, a dentist can help identify its cause.
Yes. Nudge uses nano-hydroxyapatite in a fluoride-free formula and sodium cocoyl glutamate as its cleanser instead of sodium lauryl sulfate (SLS). The result is a gentle-feeling brushing experience with restrained foam.
Natural Mint, Orange, Watermelon, and Cinnamon & Clove. Each offers its own brushing experience, while sharing the same commitment to 10% nHA. You can view the flavor-specific ingredient lists on this page.
We commissioned testing through SGS North America for lead, arsenic, cadmium and mercury. In the March 2026 report (VEU3AP), mercury was not detected above the laboratory reporting limit of 0.005 ppm; the other tested elements have measured trace values disclosed in the report. Results apply to the sample tested, rather than guaranteeing that every tube is free of all trace elements. Read the full SGS report.
Nudge offers mint and fruit flavors that can make family brushing enjoyable. Follow age-appropriate toothpaste guidance, supervise young children and check with your dental professional for individualized recommendations, particularly for children under two.
