What is Nano-Hydroxyapatite (Nano-HA)?
Nano-hydroxyapatite (nano-HA) is a biocompatible, calcium-based mineral that naturally makes up most of our tooth enamel and bone. It was originally developed by NASA to help astronauts rebuild bone density—and now, it's one of the most promising tools in modern preventive dentistry.
How Does Nano-HA Work?
Nano-HA particles are incredibly small—small enough to fill in the tiny pores and microscopic cracks in enamel. Once applied, nano-HA:
- Remineralizes the enamel
- Repairs surface damage from early cavities or acidic foods
- Protects teeth by forming a strong, natural barrier
- Reduces sensitivity in teeth affected by wear or early decay
It mimics the natural structure of enamel, so it works with the body—not against it.
✅ Benefits of Nano-HA for Kids
- Safe and non-toxic (even if swallowed)
- Fluoride-free option for families who prefer alternatives
- Gently rebuilds and strengthens enamel
- Reduces tooth sensitivity
- Helps prevent early cavities and white spot lesions
- Can be used daily at home or in-office as part of a preventative care plan
Where Can Nano-HA Be Found?
Nano-HA is found in:
- Certain toothpastes and gels designed for children and adults
- Products used in patients with braces to help prevent white spots
Is Nano-HA a Replacement for Fluoride?
Nano-HA is a fluoride alternative, not necessarily a replacement. Both fluoride and nano-HA help remineralize teeth—but in different ways. We’re happy to help you choose the best option for your child based on their individual needs, habits, and risk for decay.
