15 Dec Hydroxyapatite Toothpaste: A Safer Alternative to Fluoride
Have you heard about hydroxyapatite toothpaste? Some people are calling it “synthetic enamel” because it’s so good at strengthening the teeth. It can help remineralize the tooth enamel and relieve sensitivity. And it’s also a safer alternative to fluoride toothpaste, especially for toddlers and young children. Our dentists explain what it is and how it works.
What Is Hydroxyapatite?
Hydroxyapatite is a form of calcium phosphate. It’s a naturally occurring mineral that makes up about 90% of the tooth enamel and 70% of the tooth structure. It can be synthesized for use in dental products, which is how it came to be known as “synthetic enamel.”
It was discovered by a NASA scientist who proposed it as a method of tooth repair for astronauts affected by zero gravity. Using the same natural ingredient that composes tooth enamel to repair damaged teeth proved highly effective. In fact, it was one of the earliest examples of biomimetic dentistry: imitating the body’s natural biology to solve biological problems.
Is Hydroxyapatite Toothpaste Safe for Kids?
Yes! Hydroxyapatite is biocompatible, so it is not harmful if swallowed. This is good news for parents who have concerns about fluoride toothpaste.
Although fluoride can help strengthen tooth enamel and prevent cavities, it may be harmful to the neurological development of infants and children. And since young children tend to swallow at least some of their toothpaste (either intentionally or accidentally) every time they brush, hydroxyapatite offers a much safer alternative.
Using a fluoride alternative will also help prevent the risk of fluorosis in children’s teeth. This excess of fluoride can actually weaken the enamel. It makes white spots on the teeth that eventually turn into cavities. Overexposure to fluoride can also affect the development of the permanent teeth, increasing the risk of cavities and sensitivity.
Best Toothpaste for Sensitivity
Adults who experience pain from sensitive teeth may want to try using hydroxyapatite toothpaste. Hydroxyapatite can help repair thin or porous enamel and create a harder tooth surface. It also helps strengthen and protect the roots of the teeth if they become exposed by receding gums.
Just remember, toothpaste alone isn’t capable of fully repairing tooth enamel. Some types of damage are permanent, and you will need to see a dentist who can repair it for you.
