What's the deal with Hydroxyapatite Toothpaste?

Your favorite influencer uses it. You're getting Facebook ads about it. So, what is Hydroxyapatite and why should you care if it's in your toothpaste? 

What is Hydroxyapatite?

Hydroxyapatite is a mineral that naturally occurs in your teeth and bones. It is one of the minerals that make up your teeth's enamel - the hardest substance in the body. 

Sometimes called HA for short, hydroxyapatite is vital when it comes to good dental health, playing a key role in remineralization - the continuous process of repairing and building strong tooth enamel.

What is Hydroxyapatite Toothpaste?

Hydroxyapatite toothpaste is generally seen as an alternative to fluoride-based toothpaste. Used in Japan for over 30 years, hydroxyapatite toothpaste is considered to be the gold standard to fight cavities. 

While there are varying formulas, toothpaste with hydroxyapatite has many benefits. 

  • HA strengthens enamel and restores teeth to normal, healthy levels
  • HA promotes remineralization, helping with preventing dental caries
  • HA is a suitable alternative for people with allergies to fluoride ingredients
  • HA is less abrasive than fluoride and  can help lessen sensitivity

Is Hydroxyapatite Toothpaste good for your teeth?

As HA fights demineralization, it strengthens tooth enamel which can help you avoid sensitivity, bacteria, plaque, and periodontitis.

It also plays a roll in helping protect teeth against the forces of chewing, crunching and grinding. 

Do dentists recommend Hydroxyapatite?

Hydroxyapatite toothpaste has replaced fluoride toothpaste as what I recommend to all of my patients. 

We made hydroxyapatite toothpaste that's just as effective as traditional toothpaste with natural ingredients that are safe to put in your mouth—a tasty toothpaste for whiter, stronger, and healthier teeth for kids (and adults!).
