10 Reasons To Use Fluoride-Free Toothpaste

Every where you look, you’ll be told you NEED fluoride in your toothpaste. But the reality is fluoride-free toothpaste is just as good if not better than fluoride toothpaste.

Now I understand many of you think fluoride is some magical cure for tooth decay.

But millions of people have dropped fluoride from their dental routine, started using fluoride-free toothpaste and have perfectly healthy teeth.

10 Reasons To Use Fluoride-Free Toothpaste

1. Fluoride is Poison

Many people have no clue but fluoride is poison.

I know this is hard to believe but the proof is right on the toothpaste tube.

For example, in the picture below I compare two toothpastes from the same company, a fluoride-free and fluoride version. Now the only difference between the two is that one has fluoride and the other one does not, while all other ingredients are the same.

fluoride toothpaste vs fluoride free toothpaste

As you can tell, the one with fluoride has a poison warning.

While the fluoride-free toothpaste does not.

This is due to the fact, each and every fluoride toothpaste sold in the USA and Canada is required by law to be labeled with a poison warning.

If you’re still not convinced, here’s another picture (the one on the right is what’s added to your toothpaste).

Now if you need more reasons than this to start using fluoride-free toothpaste, you’re in luck.

I have another 9 reasons.

2. Your body does NOT need fluoride

Not ONE disease is caused by a lack of fluoride, not even tooth decay.

Furthermore, there is not a SINGLE biological process that requires fluoride.1,2,3 This is why unlike vitamin D, K, calcium and many other vitamins and minerals – fluoride is NOT an essential nutrient.

In other words, your body does not want or need fluoride to function.

3. Your teeth contain LESS than 2% fluoride

You would think from everything we read and are told, our teeth would be full of fluoride.

However, your teeth contain less than 2% fluoride. In fact, mineralized enamel is made of 89% calcium hydroxyapatite and small amounts of calcium carbonate (4%), calcium fluoride (2%), and magnesium phosphate (1.5%).4

So how does it make sense to focus on the 2% while ignoring the rest?

It doesn’t, which brings us to the next reason…

4. Focusing on the WRONG Thing

Fluoride is shoved into our mouths because it’s supposed to help with remineralization.

Now considering remineralization is a natural repair process for teeth, remineralization of teeth heavily depends on diet, many people’s diets are loaded with fluoride AND less than 2% of teeth contain fluoride. It’s clear that our bodies do not need or want fluoride.

If your body thought fluoride was useful, it would use it.

So if preventing cavities is important to you, wouldn’t it make more sense to focus on nutrients that are essential to your body, found in your teeth, and proven to be important in remineralization?

Of course it does!

remineralization of teeth process

This is why you should focus on giving your body the nutrients it needs like vitamin D and calcium.

Which is very important since 44.1% of the U.S population does not meet the daily requirement for calcium. In addition, 94.3% of the U.S population does not meet the daily requirement for vitamin D – an essential nutrient that helps the body absorb calcium and phosphorus which makes up over 95% of your teeth.5,6

So forget about fluoride, get yourself a fluoride-free toothpaste, and focus on what your body NEEDS.

If you don’t, you’ll be like an architect focusing on what color to paint the building walls instead of making sure the foundation is strong and won’t collapse (aka, their main job).

5. Fluoride Toothpaste Could Lead To Poor Quality Teeth

Does fluoride actually re-mineralize your teeth?

Now as explained above, when it comes to how it’s done naturally the answer is NO but if you directly apply fluoride to your teeth, like when you use toothpaste, then of course it “re-mineralizes” your teeth.

Since fluoride is negatively charged, it will react with positively charged ions found in your teeth like calcium. When it does this, it basically depletes natural hydroxyapatite and makes it’s own fluoride version.

This could be a problem because when it comes to bones, researchers out of the University of Toronto have uncovered that fluoride helps BUILD bone but the strength of bone declined with increasing fluoride content.7

So what makes us think that teeth are not effected in a similar negative way?

Everyone agrees that fluoride “builds” bone but the bone it builds is weak and leads to fractures. So sure fluoride “re-mineralizes” your teeth but does it do a good job?

6. Safe and Just as Effective Fluoride-Free Toothpaste

Studies have shown fluoride-free toothpaste containing hydroxyapatite is just as effective in remineralization and preventing cavities as fluoride toothpaste.8

The main ingredient in these toothpastes is a naturally occurring mineral form of calcium apatite which is actually found in our teeth.

So by going with a fluoride-free toothpaste containing hydroxyapatite you get the small benefits a fluoride toothpaste would give you just WITHOUT risking the negative effects that come with fluoride.

But considering remineralization depends heavily on diet and reason #10 of this article, I personally don’t use hydroxyapatite toothpaste and instead use something else. Which you can read at my best fluoride-free toothpaste article.

7. Fluoride is NOT Natural

Look at every other website and I can guarantee you they mention how “natural” fluoride is.

Unfortunately, they’re lying to us…

Clearly, fluoride is NOT natural. As we’ve already mentioned here… fluoride is not an essential nutrient, your teeth contain less than 2% fluoride and let’s not forget the huge “TOXIC” signs printed on the fluoride packaging (pictured below).

Casey Krol pointing at a sodium fluoride bad labelled toxic, saying "does that look natural to you"

Now technically fluoride is “natural” but this is misleading.

Lead, arsenic and mercury are ALL natural but they’re the top 3 most toxic substances on the Earth.

The only thing that matters when deciding if something is “natural” for humans is to figure out the natural levels of a substance humans have been exposed to throughout time. And when it comes to fluoride, natural foods (eggs, meat, milk, and fruits), surface water, and human breast milk (as natural as it gets) contains very low levels of fluoride – practically non-existent.

8. Fluoride Toothpastes Are LOADED With Toxic Ingredients

Not only is fluoride toxic but you’ll find other toxic ingredients in toothpastes that contain fluoride.

In fact, I could not find a single fluoride toothpaste that has good ingredients.

You can easily check this for yourself by looking at whatever fluoride toothpaste you have in mind and checking to see if it contains any of the following ingredients:

  • hydrated silica,
  • sorbitol, 
  • sodium saccharin, 
  • titanium dioxide, 
  • glycerin, 
  • sodium lauryl/laureth sulfate,
  • fluoride
  • carrageenan
  • PEG-8, PEG/PPG
  • artificial color (ex. blue 1, yellow 10)
  • endocrine disruptors (ex. lavender)

Now I’m not sure why it’s like this…

Maybe the brands that sell fluoride toothpaste know those who use fluoride don’t really care what they put into their body.

While in comparison, fluoride-free toothpastes contain much less toxic ingredients with some brands being completely toxic-free.

9. Fluoride May NOT prevent cavities

We’re told over and over again that fluoride helps prevent cavities but where’s the proof?

Truth is, there really is not that much proof to back up the claim fluoride is a miracle cavity fighter.

In fact, there’s a lot of proof to show it doesn’t do much. This proof on why fluoride does NOT work and why it’s dangerous for your health can be found at 69 reasons to oppose fluoride (link to article).

Now in relation to cavities and toothpaste. Most websites promoting fluoride often say something like “you have the demineralization but not yet a full blown cavity in the tooth, the fluoride can be taken up into that demineralized area to help it remineralize”.

BUT we know that there is less than 2% of fluoride in teeth.

So in reality this does not match up.

And let’s not forget there are millions of people who use fluoride-free toothpaste and nothing bad happens to them. In fact, they probably have better teeth then those that use fluoride toothpaste because they know they need to focus on factors other than fluoride.

10. To have fluoride work best, you can NOT rinse which is dangerous

Many pro-fluoride people recommend you do not rinse after brushing your teeth with fluoride toothpaste and leave it on your teeth.

Now I know many of you won’t believe me, it’s even hard for me to believe.

So here’s a screenshot of a “doctor” with over 300k followers on Twitter sharing this dangerous advice:

Now I don’t know about you but leaving a toxic, non-essential, and unnatural substance on your teeth and in your mouth. Allowing it to enter your bloodstream through being absorbed into your gums and swallowed with your saliva.

Does not sound smart or safe to me…

Unfortunately, thousands of people will believe what he’s saying just because he’s a “doctor”.

But in his defense, just brushing your teeth for 60 seconds and then rinsing away the fluoride does not give it enough time to do what it’s suppose to do. So that’s another major reason why it makes NO sense to use fluoride toothpaste.

BONUS: Pro-fluoride websites and advocates have no clue what they’re talking about

There are many examples of people spreading inaccurate and dangerous information about fluoride.

Now because we don’t have all day, I’ll only show you my favorite example of what I’ve found. Which was found with many other examples on the first page of Google when you search “fluoride-free toothpaste” – so just imagine how many people read these!

Here’s my favorite one, from a Healthline article called “Why You Shouldn’t Buy Fluoride-Free Toothpaste”…

As you can see, the article claims fluoride works and is safe.

With quotes coming from “a professor of restorative dentistry at the University of California Los Angeles School of Dentistry”.

But if you were to listen to this guy’s advice, you would have damaged your child’s brain. As new research has emerged and shows babies that are exposed to fluoride levels commonly found in tap water experienced a 6 point IQ drop.9

Should You Use Fluoride-Free Toothpaste?

Well, I think it’s quite obvious that you should drop fluoride and use a fluoride-free toothpaste.

Not only do we now know fluoride is toxic, non-essential to human health, and non-natural. Which leads to countless health effects like lowered IQ, hormonal problems, and weaker bones.7,9,10

But we also know that fluoride does not have a significant effect on remineralization and its effects on disrupting dental plaque can easily be substituted with many other ingredients found in fluoride-free toothpastes.

Which defeats the whole purpose of why fluoride is included in toothpaste.
