🦷 Can Hydroxyapatite Help Remineralise Your Teeth?
Your tooth enamel is constantly going through a natural process of demineralisation and remineralisation.
🧪 Acid from bacteria and dietary sugars can remove minerals from enamel. Hydroxyapatite (HAp) is a calcium-phosphate mineral that closely resembles the mineral component of natural tooth enamel.
🔬 How does it help?
1️⃣ Hydroxyapatite particles interact with the enamel surface.
2️⃣ They can deposit calcium-phosphate minerals in microscopic surface defects.
3️⃣ This supports remineralisation of early, non-cavitated enamel lesions.
4️⃣ The result can be a smoother and more mineral-rich enamel surface.
✨ Potential benefits include:
• Supporting early enamel remineralisation
• Helping reduce dentinal sensitivity
• Supporting prevention of mineral loss
• Maintaining a smoother enamel surface
⚠️ Important: Hydroxyapatite is not a substitute for professional dental treatment. Once a cavity has formed, it generally cannot be “remineralised away” with toothpaste alone.
🪥 Good oral hygiene, fluoride where appropriate, a balanced diet and regular dental check-ups remain important for maintaining healthy teeth.
