What is Nano-Hydroxyapatite (n-Ha) Toothpaste?

Boka toothpaste is powered by nano-hydroxyapatite (n-Ha), a 100% biocompatible and non-toxic ingredient that desensitizes and remineralizes teeth. Biocompatible means it contains the same elements that make up your body — in this case, your tooth surface.

Current research shows that n-Ha is superior to conventional fluoride because it:5

  • Reduces tooth sensitivity
  • Protects against plaque build-up and cavities
  • Has significant remineralizing effects on tooth enamel
  • More resistant to acid than fluoride

What Flavors Does Boka Toothpaste Come In?

Boka Nano (n-Ha) toothpaste comes in four flavors:

Does Boka Toothpaste Really Work?

Yes. Boka toothpaste is backed by scientific research and contains ingredients designed to remineralize and strengthen tooth enamel.2,4,5

But you don’t have to simply take out word for it. Boka’s Ela Mint toothpaste has over 25,000 Amazon reviews, the vast majority of which are 5 stars!

If you’re still unconvinced, keep reading for a dentist’s expert opinion on how n-Ha toothpaste compares to fluoride toothpaste.

What the Experts Say About Nano-Hydroxyapatite Toothpastes

We asked Dr. Greg Grillo of Express Dentist his thoughts on nHa toothpaste. Here’s what he says:

“N-Ha provides an excellent alternative to fluoride. While early studies suggested fluoride offered superior protection against tooth decay, more recent studies have shown a comparable benefit. Both can protect teeth against acidic breakdown from certain bacteria, foods, and drinks. But it’s significant to note that n-Ha is non-toxic.”

-Dr. Greg Grillo

Fluoride kills bacteria, including a few of the beneficial species. But n-Ha prevents adherence of the bacteria to the tooth surfaces, so it’s less likely to disrupt the oral microbiome.

As an added benefit, some studies have shown that the nHa toothpastes may slightly whiten teeth over time. On the other hand, too much exposure to systemic fluoride can cause discoloration of the teeth, known as fluorosis.

Dr. Grillo says both formulations provide excellent benefits, and fluoride has a long history as the gold standard in cavity prevention. But the science shows that n-Ha toothpaste protects teeth with less risk, so it’s worth consideration in your daily routine.

Nano-hydroxyapatite vs. Fluoride

Nano-hydroxyapatite and fluoride promote good oral health by strengthening tooth enamel and protecting against cavities. 

These are their similarities and differences:

Nano-hydroxyapatite Effectiveness and Safety

Nano-hydroxyapatite occurs naturally in the body, commonly found in the tooth enamel. It’s a safe and effective ingredient for enamel strengthening.5

NASA originally developed n-Ha for astronauts because they lost teeth and bone density after gravity-free missions.1 It’s non-toxic and 100% biocompatible, making it an innovative material for restorative and regenerative dentistry.

The main downside of nano-hydroxyapatite (n-Ha) is that it’s less studied than fluoride. However, current research shows that n-Ha is more effective in remineralization than fluoride and may also be safer.1, 5

Fluoride Effectiveness and Safety

Fluoride naturally occurs on the earth’s surface and is a common ingredient in oral care products. Fluoride helps protect against cavities by making enamel more resistant to acids. 

Studies have even shown that fluoride can halt damage in already damaged teeth (in some cases).6 

Although fluoride is adequate for dental protection, it does have some downsides:7

  • It can be dangerous in high concentrations (especially when ingested)
  • It can decrease thyroid function
  • It can cause issues with the skeletal and reproductive systems

Pros and Cons of Boka Toothpaste

As with any oral care product, Boka toothpaste has advantages and downsides. Here are the major pros and cons based on reviews:

Boka Toothpaste Pros

  • Nano-Hydroxyapatite formula — This trustworthy ingredient is naturally restorative and has been used in Japan for many years.
  • Effectively reduces sensitivity — N-Ha is desensitizing, making this a good toothpaste for sensitive teeth.
  • Mild, natural taste — Flavors such as Ela Mint, Lemon Lavender, and Coco Ginger are mild and sourced from natural ingredients with no artificial flavors.
  • Leaves your mouth feeling clean — Like other natural toothpastes, Boka doesn’t use harsh foaming agents, but you don’t need foam to clean your teeth.

  • Tube design —  The Boka toothpaste tube has a tiny twist-off cap that some find difficult to use.
  • Inconsistent effectiveness — Some people claim that Boka Ela Mint toothpaste doesn’t clean as effectively as the other flavors
