When humans began to venture out into space, NASA quickly discovered that lack of gravity caused major problems for the astronauts teeth.

I will spare you the scientific details of how this lack of gravity affected them, but basically the enamel on their teeth began to shed the minerals that make it strong. This process is called “demineralization''.

Enamel is the hard outer layer of your teeth that makes them strong and resistant. But when enamel is demineralized, it becomes soft and susceptible to decay.

This process of demineralization happens every time you consume sugary or acidic foods or drinks. These acids slowly weaken your teeth's ability to protect themselves.

Is Fluoride Safe?

For years, fluoride has been praised as the best way to remineralize teeth by the ADA and FDA. But there is a growing number of people who are concerned about possible negative effects of long term exposure to fluoride.

Fluoride is a toxic substance at higher doses and should not be ingested, although the ADA and FDA insist that lower doses are safe. Opponents of fluoride argue that the compound effect of fluoride toothpaste and fluoride infused drinking water push people beyond the limits of what is safe.

In fact, the US is one of the few developed countries that hasn’t banned fluoride from their water supply.

Countries: Austria, Belgium, China, Denmark, Finland, Germany, Hungary, Israel, Norway, and the Netherlands have refused to use it in their water over health concerns.

Does Fluoride Lower Testosterone?

Beyond general health, there are also studies that suggest fluoride could drop in male testosterone levels (Source) and fertility (Source).

The global average testosterone levels have been dropping by 1% per year since the 80’s. While there may be several reasons for this, part of the problem is chemicals and hormone disruptors we are exposed to.

People may argue that the chemicals in any one product are not enough to drop someone's testosterone significantly. But when you count the multiple different products you use on your body or are exposed to each day, it starts to add up.

Toothpaste is a problematic hormone disruptor because we put it in our mouth and swallow approximately 7% of it each time we brush. Most people brush two to three times a day so this can be one of our largest exposures.

Low testosterone levels in men cause a host of problems such as:

• Low sex drive

• Erectile dysfunction

• Loss of strength

• Increased fat retention

• Depression

• Low motivation

• Hair loss

• Feeling tired all the time

Is There An Alternative To Fluoride?

With these concerns in mind, many have decided fluoride is not worth the risk and looked for an alternative that carries the benefits of fluoride without the potential negatives.

This is where our NASA story comes in…

Interestingly, NASA didn’t turn to fluoride when they needed a cure for their astronauts' mineral depleted teeth.

Instead they developed a new way of remineralising teeth using a substance known as hydroxyapatite.

Hydroxyapatite is a naturally occurring mineral that makes up 97% of your tooth enamel. But unlike fluoride, it is completely harmless to ingest. (Source)

When applied to your teeth at the nano particle size, hydroxyapatite is reabsorbed into the enamel, restoring it to its protective nature. This process is called “remineralization”.

Studies show nano-hydroxyapatite is highly effective at rebuilding depleted enamel…and in some cases it can even heal minor cavities.

Here is a quote from a study from the University of Rome posted on the pubmed.gov website:

 Along with protecting your teeth from cavities, nano-hydroxyapatite also:

• Reduces Tooth Sensitivity - Your teeth have micro tunnels that lead to the nerves, allowing liquid to pass through so you can feel hot and cold. Sometimes our teeth can become too sensitive though which can be painful. Nano-hydroxyapatite binds to your tooth's surface, and plugs those tunnels so those liquids can no longer travel through your teeth. This means reduced tooth sensitivity! (Source)

• Brightens Your Smile - Nano-hydroxyapatite helps rebuild the surface of the enamel, filling in micro scratches and gaps in the surface. The same way wax shines and brightens faded car paint, hydroxyapatite can shine and brighten your teeth. (Source)

• Prevents Plaque and Bad Bacteria - Nano-hydroxyapatite helps break down the plaque and harmful mouth bacteria that causes cavities. It does this without destroying the beneficial mouth bacteria that protects the mouth and promotes good gut health. (Source)
