What is Fluoride-Free Toothpaste?

Fluoride-free toothpaste is an alternative to traditional toothpaste that typically uses nano hydroxyapatite to protect your enamel.

Fluoride has been a gold standard in oral care products worldwide for removing cavities and strengthening teeth for years.

Recently, people are more and more aware of the risks of fluoride and are searching for alternatives that deliver the same efficacy as fluoride without compromising their safety.

Nano-hydroxyapatite is a promising alternative that provides equal, arguably even better, results than fluoride.

This article will explain the risks of fluoride and explore the benefits of nano-hydroxyapatite as an alternative to fluoride in toothpaste.

Understanding Fluoride

Fluoride is the most prevalent mineral that can be found in nature.

It is naturally abundant in our food, such as fish, potatoes, eggs, and meat. It is also added to drinking water, toothpaste, and other dental treatments.

The effects of fluoride on oral health have been long documented. Dental researchers have recognized its role in preventing tooth decay and strengthening the teeth for years.

How Fluoride Works

Studies show that fluoride is excellent for preventing the development of initial signs of caries and remineralizing the enamel.

In the teeth, fluoride is used to substitute hydroxyapatite in demineralized areas of the enamel. It works by forming fluorapatite with calcium and phosphate which promotes remineralization and surrounds the enamel for protection.

Fluorapatite is highly insoluble, which makes it resistant to acid attacks.

In vitro studies show that fluoride has a lower capacity for remineralizing in enamel and dentin compared to nano-hydroxyapatite.

Aside from remineralization, fluoride is also effective in controlling the growth of bacteria.

The higher the fluoride concentration, the more effective it is in reducing the incidence of caries.

The Risks of Fluoride

Although consuming fluoride from different sources is a great way to reduce the incidence of dental caries, it also has its risks.


Fluorosis is one of the side effects of overexposure to fluoride. Fluorosis only develops in early childhood when enamel formation is still in process.

Fluorosis is the formation of white and brown spots or lines on the surface of the teeth. In severe cases, this can result to enamel loss.

Children are advised to use no more than two pea-sized fluoride toothpaste and rinse it off instead of swallowing it.

Fluoride Intoxication

Another risk that comes with overexposure to fluoride is intoxication.

According to the American Association of Poison Control (AAPC), toothpaste ingestion is one of the leading causes of intoxication from fluoride. This is followed by mouth rinse and food supplements containing fluoride. More than 80% of these intoxication cases were of children.

Fluoride intoxication is categorized into two:

  1. Acute Effects
  2. Chronic Effects

Acute effects are described as follows:

  • Nausea or Vomiting
  • Hypocalcemia
  • Involuntary muscle contractions
  • Mixed metabolic and respiratory acidosis
  • Coma and convulsions

Chronic effects are described as follows:

  • Dental fluorosis
  • Skeletal Fluorosis
  • Hypersensitivity
  • Gastric irritations
  • Numbness, muscle spasms
  • Congenital disabilities or cancer

Chronic effects are more reported than acute effects.

With all these possible risks of fluoride ingestion, it is natural that one finds a safer alternative for the whole family's safety. 

What is Nano-Hydroxyapatite?

Nano-hydroxyapatite (nHA) is a synthetic version of the mineral that composes 97% of the enamel and 60% of the dentin, called hydroxyapatite (HA).

Studies suggest that nano-hydroxyapatite has excellent remineralization and bacterial reduction capabilities. Due to its biomimetic properties, it can form a synthetic layer of enamel around demineralized areas close to the natural enamel.

With the size of nHA ranging from 50-1000 nanometers, it can easily penetrate beneath demineralized areas, bond with plaque and bacteria, and repair early signs of tooth decay.

How Nano-Hydroxyapatite Works

Nano-hydroxyapatite has shown promising results in in vitro and in situ studies in terms of remineralization, teeth sensitivity reduction, whitening, and plaque buildup control.

Enamel Remineralization

Nano-hydroxyapatite is deemed to have significantly better results in remineralizing the demineralized enamel versus other remineralizing agents.

The nHA particles form into micro clusters, creating a synthetic enamel layer around the teeth.

Due to its size, it can easily penetrate exposed dentinal tubes and fill microabrasions on the enamel's surface.

Furthermore, nano-hydroxyapatite serves as a local reservoir of calcium and phosphate crucial for remineralization.

Reducing Teeth Sensitivity

Teeth sensitivity happens when the enamel wears out, and the dentin and dentinal tubes are exposed.

Hydroxyapatite crystals and other minerals are too large to penetrate the dentinal tubes. However, nano-hydroxyapatite is small enough to penetrate tiny dentinal tubes and bond together to form a layer of protection around the teeth.

Studies show that nano-hydroxyapatite is 23% more effective than fluoride in reducing teeth sensitivity.

Plaque Buildup Control

Fluoride has always been the standard for removing plaque formation and improving periodontal health.

In recent years, dental researchers have become more interested nano-hydroxyapatite's biofilm control.

Due to its biomimetic properties, nano-hydroxyapatite is able to inhibit the development of plaque while keeping the microbiome in balance.

nHA works by bonding with bacteria and plaque, hindering it from attaching to the surface of the enamel. Nano-hydroxyapatite, in particular, has a greater surface area where bacteria could attach. 


In vivo and in vitro studies suggest that nHA whitens the teeth through remineralization, which creates a smoother and brighter appearance around the teeth.

While whitening agents such as hydrogen peroxide and other dentifrices whiten the teeth mechanically or chemically, nHA works physiologically. It also fills holes and microabrasions that make the teeth look dull.


Since nano-hydroxyapatite is biocompatible, it is non-toxic and non-inflammatory. Even if ingested, it does not present any risks due to its biomimetic properties.

People of all ages can use nano-hydroxyapatite toothpaste.

Nano-hydroxyapatite toothpaste tablets are pre-dosed with enough concentration as advised per use.

Final Thoughts: Is Nano-Hydroxyapatite a Good Alternative to Fluoride Toothpaste?

Nano-hydroxyapatite is an excellent alternative to fluoride in toothpaste.

It delivers superior remineralizing, biofilm control, whitening, and teeth sensitivity reduction abilities without the risks of intoxication and fluorosis.
