What are fluoride-free toothpastes?

Fluoride free toothpastes are generally formulated with alternative remineralizing agents to fluoride, like nano hydroxyapatite.

However, many natural toothpaste brands claim to be fluoride free while leaving out any ingredients that promote remineralization.

For those that are interested in trying a fluoride-free toothpaste, consider using a product that contains nano hydroxyapatite.

Nano hydroxyapatite toothpaste is a promising fluoride-free option that provides equal results compared to fluoride, some even argue it can be more effective.

This article will explain the reasons why people avoid fluoride and explore the benefits of nano-hydroxyapatite in fluoride-free toothpastes.

What is fluoride toothpaste?

toothpaste, fluoride toothpaste

Fluoride toothpastes use fluoride as a remineralizing agent to strengthen your tooth enamel.

Fluoride is the most prevalent ingredient used in toothpastes to prevent tooth decay.

While there are many forms of fluoride, calcium fluoride is even found in nature. It can be found in water, soil, plants, air, and rocks.

For decades, fluoride has been the gold standard in traditional toothpaste worldwide as a means to:

  • Prevent tooth decay

  • Fight plaque

  • Improve oral health

Aside from that, fluoride is also used to provide relief for sensitive teeth and help your teeth rebuild themselves after contact with acid.

How does fluoride toothpaste work?

toothpaste, toothbrush, brush teeth

Studies show that fluoride toothpaste can prevent cavities by improving your enamel's resistance to acid.

Dental experts believe that using fluoride from different sources is one of the best ways to prevent cavities.

Some of the most common sources of fluoride for oral health include:

  • Fluoridated water

  • Mouthwashes and mouth rinses

  • Fluoride supplements

In many dental products containing fluoride, a fluoride ion is substituted in the chain of hydroxyapatite in demineralized teeth. This creates resilience in teeth against acid and cavity-causing bacteria.

At high concentrations, fluoride toothpastes deposit calcium and phosphate ions back into your teeth. This reverses the demineralization process and protects you from tooth decay.

Aside from remineralization, fluoride is also effective at controlling bacteria growth and caries incidence.

These benefits are the driving factors behind the American Dental Association approval of products containing fluoride as a way to prevent tooth decay.

Side Effects of Fluoride

To some people's surprise, consuming fluoride comes with certain risks that you probably weren't taught about!

Here are some of the key reasons why you should avoid fluoride in toothpaste:

Dental Fluorosis

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

Dental fluorosis is the formation of white and brown spots or lines on the surface of the teeth. In severe cases, this can result in hypomineralization and enamel loss. 

In fact, avoiding dental fluorosis is one of the biggest benefits of fluoride-free toothpaste.

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

Fluoride Allergy

Surprisingly, fluoride toothpastes can cause an allergic reaction.

Although uncommon, fluoride can result to mouth lesions, a rash, tightness in the throat, or trouble swallowing.


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 found in children.

Fluoride intoxication is categorized into two:

  1. Acute Effects

  2. Chronic Effects

Acute Intoxication Effects

Acute effects are described as follows:

  • Nausea or vomiting

  • Hypocalcemia

  • Involuntary muscle contractions

  • Mixed metabolic and respiratory acidosis

  • Coma and convulsions

Chronic Intoxication Effects

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.

Of course, please consult with a medical professional if you ingest fluoride!

Many dental professionals love nano hydroxyapatite as it is effective at preventing cavities and reducing tooth sensitivity.

By using nHA, you'll get even more effective dentin remineralization than you would with calcium and phosphate alternatives.


Nano hydroxyapatite is an effective remineralizing agent found in toothpaste.

While nano particles have previously been scrutinized for safety, evidence suggests that they are safe at up to 10% nano hydroxyapatite concentration in toothpaste.

Not to mention, the inclusion of nano hydroxyapatite particles in toothpaste may offer a better alternative to fluoride, which has been associated with toxicity concerns in some cases.

Prevent Tooth Decay

Some dentists recommend nano hydroxyapatite as a fluoride-free alternative for its remineralization properties.

In fact, studies show that nano hydroxyapatite exhibits impressive remineralization results which can prevent tooth decay. exhibiting significantly better remineralization results.

Teeth Sensitivity

Since nHA particles are so tiny, they can easily penetrate exposed dentinal tubes caused by demineralization and lessen teeth sensitivity.

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

Biofilm Control

Due to its biomimetic properties, nano hydroxyapatite is able to fight plaque while supporting a healthy oral microbiome.

Whitens Teeth

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

Typically, hydrogen peroxide and other whitening agents whiten teeth mechanically or chemically.

On the other hand, nHA in a whitening toothpaste like NOBS makes your teeth appear brighter by filling in microabrasions and holes.

What's wrong with most fluoride-free toothpastes?

Unlike NOBS by Biöm, most fluoride free toothpaste brands formulate their products without any understanding of oral health.

Typically, these brands leave out the most important ingredient in your toothpaste - a remineralizing agent, like nano hydroxyapatite!

In addition many of these natural toothpaste companies will include essential oils such as tea tree oil, peppermint oil, coconut oil, activated charcoal, aloe vera, fresh mint, or even green tea.

These additional ingredients are not sufficient for remineralization, which is important for healthy teeth and fighting cavities.
