Hydroxyapatite: toothpaste ingredients you need to know more


Fluoride is already the standard ingredient in anti-cavity toothpaste – and it can be part of your current oral care routine – but modern oral care brands are eyeing a solution. science-backed alternative: hydroxyapatite. While you won’t find the ingredient in most major drugstore formulas, hydroxyapatite has more than four decades of research and oral care applications to back it up. What’s more, it’s non-toxic and biocompatible, making it a viable option for those looking for natural oral care solutions. Read on to learn more about this dentist-approved ingredient and find the best hydroxyapatite toothpaste.

“Hydroxyapatite (HAp) is a major component of tooth enamel and is one of the most studied biomaterials in the medical and dental fields.” Dr. Jonathan B. Levinedental director of oral health brand Lenny Kravitz Twice. “It makes up the main mineral portion of bones and teeth – in fact more than 90% of the foundation of enamel.” As the outermost layer of teeth and the hardest substance in the human body, maintaining healthy enamel is essential for your teeth and overall health. It protects the inner elements of the teeth from bacteria and cavities, which when exposed can lead to cavities, serious infections, gum disease and even tooth loss.

The medical applications of hydroxyapatite are led by NASA in the 1970s, because astronauts lose minerals in their teeth and bones due to the lack of gravity in space. In 1974, the Japanese company Sangi Co. Ltd. acquired a NASA patent for the use of hydroxyapatite in the field of dentistry, finally created the world’s first nano hydroxyapatite toothpaste in 1980 and patented the component in 1990.

“HAp doesn’t have the controversial issue of too much fluoride and is safer in many people’s minds,” says Levine. (Although the dentist notes that since we don’t swallow toothpaste, fluoride is “100% safe to use and essential for some people who need the strong effect on weaker tooth enamel that fluoride provides. “)

He continues: “At the small particle size – micro or nano – HAp helps to form a protective layer on enamel and cementitious surfaces. This is a process known as remineralization, where hydroxyapatite binds to tooth enamel and fills the tubules (microscopic channels that go inside the tooth and can cause sensitivity to contact). According to Levine, numerous studies have shown that hydroxyapatite aids in the remineralization of small initial decay and is “more effective than fluoride.”

Hydroxyapatite can be a substitute for fluoride, but it’s also safe to use with fluoride, and some toothpaste formulations will combine the two. “Both hydroxyapatite and fluoride are minerals that can repair damage caused by tooth decay.” Dr. Chris Saliernodental director at There is a tendency. “Fluoride can kill bacteria, while hydroxyapatite prevents bacteria from attaching to teeth.”

Enamel remineralization is the primary benefit of hydroxyapatite. By strengthening tooth enamel, teeth are better protected against plaque, which can cause tooth decay and gum disease. While fluoride also fights tooth decay, it does not contain calcium and phosphate. These minerals are found in hydroxyapatite and enamel, which help prevent tooth decay. “[Hydroxyapatite] Salierno explained.

Because hydroxyapatite occurs naturally in our bodies, it is non-toxic and biocompatible, unlike fluoride. This also helps to keep children safe who may accidentally swallow the toothpaste.

While you won’t see the benefits of hydroxyapatite — enamel is semi-translucent and Levine says “the remineralization happens at the micrometer level” — you can feel it. Hydroxyapatite helps relieve tooth sensitivity by filling the aforementioned tubes, which are essentially microscopic pathways to the nerves in the teeth. With fewer tubes in contact, you will feel less sensitivity and discomfort to touch, food and temperature.
