The Benefits of Nano-Hydroxyapatite Gum for Enamel Restoration

Nano-hydroxyapatite is a synthetically made instance of the same mineral that composes 97% of tooth enamel and 70% of dentin. n-HAp was developed by NASA in the 1970s to assist astronauts in rebuilding bone and tooth density they lost in outer space, but since then has become a popular and studied fluoride alternative for tooth remineralization.

Fluoride triggers mineral absorption from saliva, but n-HAp [nano-hydroxylapatite] creates actual chemical and physical bond with as well as fills in the inorganic matrix surface to make n-HAp, essentially mimicking and restructuring the natural structure of teeth..

NATHAN&SONS

Why Nano-Hydroxyapatite Gum Is Effective for Enamel Restoration

1. Longer Contact with Enamel
Saliva plays a crucial role in neutralizing acid and transporting minerals to your teeth. When you chew gum, you stimulate saliva production. Nathan and Sons’ gum uses this process to naturally deliver n-HAp to weakened enamel areas over an extended period.
2. Non-Acidic, Sugar-Free, and All-Natural
Many gums contain artificial sweeteners or acids that can wear down enamel. Our formula uses xylitol, a naturally derived sweetener that has been shown to reduce cavity-causing bacteria. It’s also safe for people with diabetes and doesn’t cause blood sugar

NATHAN&SONS

Nathan and Sons chewing gum includes:

  • Nano-Hydroxyapatite: The active ingredient for enamel remineralization and reduced sensitivity.
  • Xylitol: A sugar alcohol that helps inhibit Streptococcus mutans, the bacteria most responsible for cavities.
  • Natural Flavors: Mint and other essential oils for fresh breath and a pleasant chewing experience.
  • Gum Base: Plant-based and free of synthetic chemicals, ensuring longer chew time without toxins.
  • No Artificial Sweeteners, Dyes, or Preservatives

This formulation is designed for safety and efficacy across a broad age range—from young children learning to care for their teeth to older adults preserving theirs.

Comparing Nano-Hydroxyapatite vs. Fluoride

For decades, fluoride has been the standard for enamel remineralization. However, emerging research shows that n-HAp may offer similar—or even superior—benefits without the potential risks of overexposure (especially in children).

Because n-HAp is biomimetic (meaning it mimics the natural structure of enamel), it's particularly suitable for children, pregnant women, and individuals seeking fluoride-free dental care.

Fills in Microscopic Enamel LesionsNano-hydroxyapatite particles are small enough to penetrate the surface of damaged enamel and begin repairing tiny imperfections. Over time, this can lead to smoother, stronger teeth and a visible reduction in sensitivity.

    Long lasting and pleasant!

    This is the real deal. Expensive, but probably worth it. As others note, the initial flavour disappears quickly, but you can chew for hours which is great for mewing and dental health in general. If I take the gum out to eat or drink something, when I pop it back in, there is a pleasant but subtle flavor.

    I've only chewed two or three pieces, but my teeth feel better already! Thank you Nathan & Sons!

    Love these, 2-3 a day and both my mouth and mind feel better

    I love these, it's like getting in another brushing of the teeth mid-day without actually having to brush your teeth. Like my mouth actually feels cleaner after chewing these. Thank you for embracing what our ancestors spent thousands of years perfecting.

    Highly recommended! I’ve bought twice! Use everyday!

    I struggle with bad breath despite good oral hygiene. normally gum gives you instant fresh breath but in the long run, the sugar and chemicals seem to make it worse. Since i’ve switched out for this my breath is better and my mouth even feels better. highly recommend. just one complaint though, please make a bulk value pack or set!

    Great Natural Gum!

    Was my first time ordering natural gum. Was initially skeptical but it was a great experience. Shipping was quick. The gum is very pleasant. The flavor doesn’t last long but the gum sure does. Most gum melts the longer you chew it. This one last for quite a while. Definitely enjoyed it. Will be ordering again!

    Love it! Tasty and makes

    Love it! Tasty and makes my teeth feel nice and clean afterchewing. One piece at a time is definitely enough. Obviouslythe flavor goes away quickly but that's not the point of thisgum. Unsure if it's improved my oral health yet but it makesme feel like l'm doing something healthy.

    This gum changed what I’ll buy forever

    Absolutely love this gum! I got the mint flavor and the first few chews are packed with a delicious, clean minty burst. While the flavor fades after a few minutes, the chewing experience stays solid — firm but not too hard, and it doesn’t stick to my teeth. I’ve tried Tide, 5 Gum, and Orbit before, but this blows them all away. Even after the flavor fades, it still tastes better than most gums out there.

    How does this gum remineralize my teeth?

    Your teeth are in a constant state of demineralization and remineralization.

    Our gum is packed with the vital minerals our teeth need to effectively remineralize and repair. In addition to phosphorus, iron, copper and zinc, our gum contains hydroxyapatite which is the same compound our teeth are made of. This combination of minerals helps to rebuild tooth enamel and combat decay.

    What does it taste like?

    We flavor our gum with a combination of organic mint essential oils and natural and organic mint flavors. Our gum uses three primary types of tree sap (Mastic, Spruce, and Chicle), each adding its own flavor. Mastic adds a subtle piney and herbal flavor, while spruce adds minor notes of fresh pine and earth. Overall, most people say our gum tastes like a sweet mint with a subtle and pleasant herbal undertone.

    How long before l start seeing results?

    While results may vary, chewing the gum for at least 30 minutes will result in teeth that are smoother. Most food particles and other debris will have also been removed. (You should still floss!) For best results, a consistent daily chewing routine is recommended. Most people notice a healthier smile, a reduction in bad breath, and less sensitive teeth and gums after 30 days. The longer you chew, the better the gum works and the more noticeable the results will be.

    Why is Underbrush gum more expensive than regular gum?

    Plastic and artificial sweeteners are the primary ingredients used in store-bought gums. The mysterious "gum base" ingredient you see on the back of every pack of gum is often a mix of synthetic plastics, rubbers, softeners, emulsifiers, and flavor modifiers. These ingredients cost just tiny fractions of a penny. In fact, the most expensive piece of store-bought gum is often the packaging. These gums serve no real purpose and offer no benefit to our mouths or the planet.

    Our chewing gum is made of natural ingredients like chicle, mastic, and spruce saps. These natural saps can only be harvested at specific times throughout the year. Only a small amount of these potent saps are taken to prevent damage to the tree. However, nurturing these trees is a year-round effort that requires immense manual labor. High-quality ingredients and the labor associated with obtaining them add to the final cost of the gum.

    While big gum brands have the luxury of fully automated processing, our production process requires a large human component. Much of our production must be done by hand and relies on the experience of farmers, foragers, and crew dedicated to making the best gum in the world.

    Each one of our ingredients serves a purpose and was selected for its beneficial properties.

    You will not find any filler ingredients used simply because they are cheap to source. We only use real ingredients.

    Our gum is made with the very best natural ingredients for people who value alternatives to the disturbing amount of artificial products in our lives.

    How many pieces of gum should I chew per day?

    What will the gum texture feel like in my mouth?

    The texture is nearly identical to most store-bought gums but slightly stiffer.

    How chewy is your chewing gum?

    Our gum base is made of natural tree saps which means that our gum is slightly more stiff at the start and maintains a stronger shape throughout your chew. This increases the amount of food, gunk, and plaque that our gum can scape off your teeth. As a bonus, chewing on this gum will strengthen your jaw for a more defined jaw line.

    Is Underbrush Gum Gluten-Free?
