Overview

This video explains the science behind hydroxyapatite (HAP) toothpaste, its effectiveness in rebuilding enamel and reducing stains, and how it compares to fluoride and other oral care products. It also provides guidance on choosing effective HAP toothpastes and how to use them for optimal results.

Key takeaways

• Hydroxyapatite (HAP) is a naturally occurring mineral in bones and teeth that can be used in toothpaste for cavity prevention. A nanoparticle version was developed by NASA and later patented for toothpaste by a Japanese company.
• For HAP to be effective in toothpaste, it needs to meet specific criteria: nano-sized, rod-shaped particles at a final concentration of 10%.
• HAP works differently than fluoride: HAP already contains calcium and phosphate ions, so it doesn't rely on saliva for effectiveness and helps rebalance oral pH. Fluoride, on the other hand, needs calcium and phosphate ions from saliva to form fluorapatite for surface-level remineralization.
• Effective HAP toothpaste can rebuild enamel on a microscopic level, repair roughness, reduce staining, and help with sensitivity. It smooths the enamel surface, making it harder for plaque and biofilm to adhere.
• The speaker recommends specific brands that follow the science: Apagard Royal (Sangi), vVardis, and Dr. Jen's Natural. Dr. Jen's is highlighted for its effectiveness and cleaner ingredients.
• To maximize effectiveness, it's recommended to spit out excess toothpaste after brushing but avoid rinsing to allow the HAP time to bond with the teeth.
