What Is Nano Hydroxyapatite Gum?

Nano hydroxyapatite chewing gum is a cutting-edge advancement in oral care that allows you to protect and strengthen your teeth naturally, just by chewing. Made with nano-sized particles of hydroxyapatite, the mineral your tooth enamel is made of, this gum supports the natural remineralization process your body is designed to do on its own.

Nano hydroxyapatite has been used for decades in Japan and Europe as a safe, effective alternative to fluoride. Originally created by NASA to protect astronauts’ teeth from decay in zero gravity, it has since become a trusted solution for restoring enamel, reducing sensitivity, and whitening teeth gently without harsh chemicals.

Now, Nathan & Sons brings this powerful ingredient to you in a convenient, clean, great-tasting chewing gum.

Why We Created Underbrush Gum With Nano Hydroxyapatite

To give you an easy, on-the-go way to care for and strengthen your teeth throughout the day!

Your enamel is under constant attack from acidic foods, sugary snacks, and environmental stressors. Traditional brushing alone often isn’t enough, and many fluoride products come with warnings or unwanted side effects.

Our chewing gum with nano hydroxyapatite is a natural, fluoride-free option that works in harmony with your body. It supports stronger enamel, fresher breath, and healthier teeth in a way that fits seamlessly into your daily routine.

What Makes Nano Hydroxyapatite Chewing Gum Different?

Unlike ordinary gum, which may freshen your breath but offers no real dental benefit, nano hydroxyapatite chewing gum is functional. It actively protects and repairs your teeth every time you chew. Here’s how:

Whitens Teeth

The smooth layer it forms reflects light more evenly, creating a naturally whiter appearance without bleach or peroxide.

Strengthens teeth

Nano hydroxyapatite particles bind to enamel and dentin, filling in microscopic holes and strengthening weak spots.

Reduces tooth sensitivity icon - Snowflake symbol

Reduces Sensitivity

It helps block open dentin tubules—reducing tooth sensitivity caused by exposed nerve endings.

Cavity Prevention

It neutralizes acids in your mouth after meals, helping to prevent cavities and tooth erosion.

How to Use Nano Hydroxyapatite Chewing Gum

Use nano hydroxyapatite gum just like regular chewing gum, except now it’s working for your teeth, not just your taste buds.

With consistent use, most people begin to notice reduced sensitivity, smoother teeth, and a cleaner feeling mouth, often within just a few days.

Step 1

Chew 1–2 pieces after meals or snacks

Step 2

Use up to 3 times a day for best results

Step 3

Make it part of your daily routine at work, on the go, or after coffee
