Why Water Fluoridation Isn’t the Answer for Healthy Teeth

When I first heard there was fluoride in our water supply, I was sitting in a consultation room with a Nutritionist as I was having a really hard time with low energy, depression and anxiety. At 23 years old I’d hit rock bottom with my health and I was ready to find the root cause of why I was feeling so unwell.  

I was advised to filter my drinking water to avoid fluoride as it reduces iodine levels in the body which over time can impact your thyroid health which governs your hormonal system.  

I followed my healing plan as though it was my full-time job and after 6 months, I was feeling really well and balanced. I was so excited that I organised for Barbara Wren my Nutritionist to give health talks in my home town of Tralee, Co. Kerry. With the focus on mental health, Barbara kept saying how important it is to get the fluoride out of our drinking water.  

I didn’t think much of it other than “get a filter and that will be it”.  

As Barbara was about to leave at the airport, she said to me “You should try to get the fluoride out of the water in Ireland”. In that moment, it was like she placed a harpoon into my chest and something opened in me that wasn’t there before. I knew deep down in my heart that I had to do something about this.  

I started delving into the scientific literature and discovered that water fluoridation isn’t as safe and effective at the optimal level as we’ve been made to believe since it was first added to Ireland’s water back in 1964.  

Before I share with you what I found I’d like to give you some context to help you see the bigger picture.  

Ireland is the only country in Europe with mandatory water fluoridation policy since 1964.

97% of Europe has banned or rejected the practice of adding artificial fluoride to water.  

Countries that don’t fluoridate include Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Italy, Luxembourg, Netherlands, Northern Ireland, Norway, Portugal, Scotland, Sweden, Switzerland, Croatia, Estonia, Hungary, Iceland and Latvia and approximately 90% of both the United Kingdom and Spain.  

Holland banned water fluoridation by law. This law came into effect because it was widely perceived that drinking water should not be used as a vehicle for pharmaceuticals.  

Dr Hans Moolenburgh’s research in Holland found that people experienced health problems following the addition of fluoride to the Amsterdam water supplies in 1972. 

The problems included gastrointestinal disorders, mouth sores, rashes, headaches and forms of arthritis. Follow-up research in 1993 revealed significant increases in the incidence of cancer, arthritis and neurological complaints, he reported.

You’re drinking water every day and using it for teas, coffees and cooking and the question in your mind is does fluoride impact your health? 

To answer that question, you have to look into what’s fluoride. Fluoride, like iodine, chloride and bromine is in the family of halogens. According to Dr. Brownstein, the author of Iodine: Why you need it, why you can’t live without it, fluoride is known to be a toxic agent.

It has been shown to inhibit the ability of the thyroid gland to concentrate iodine. Research as shown that fluoride is much more toxic to the body when there is iodine deficiency present. When you have iodine deficiency you have an increased risk of developing thyroid dysfunction, which is really common, because iodine acts as an antiseptic to the thyroid so when you have a deficiency you’re most likely to succumb the a thyroid condition which is caused in 95% cases by the Epstein Barr Virus.

Fluoride is an aluminium by product that’s highly toxic to your liver, causing liver cell damage.

In recent years studies have shown how fluoride impacts neurological health negatively.

In The Case Against Fluoride by Dr Paul Connett, Dr. James Beck, and Dr. H. Spedding Micklem, they expressed particularly concerned about is the impact of consuming water at 1 ppm over an extended period of time.

In the case of infants, a huge concern is the possible impact on their mental development over the first few years of life, since studies have shown that levels as low as 1.9 ppm fluoride in water are associated with a lowering of IQ in China.

 In the case of adults, we are concerned about lifelong exposure to levels of 6 mg per day or even lower and what damage that might do to bones and ligaments.

The debate of the science around fluoride has been going on since the 1960s. It’s clear to see that there are enough red flags to stop this practice based on the precautionary principle. 

The only reason its added is to prevent tooth decay, yet The World Health Organisation found that countries that stopped adding fluoride to water have seen the same dental decay rates drop as those that do add fluoride. The main solution to reduced dental decay is better oral hygiene and improved diet.  

Scotland who don’t fluoridate the water supply run a successful programme called Child Smile which teaches young children at nursery school how to properly brush their teeth giving them healthy habits they need to take care of their oral health for life.  

Adding fluoride to our water is an outdated practice and it’s time to give everyone a choice and join the rest of Europe who don’t add fluoride chemicals to drinking water.

The belief that fluoride is good for teeth is deeply ingrained in the collective and individual consciousness.

It’s time to release the belief and it starts with you, understanding how to truly support oral health.

But Aisling, if water fluoridation stops won’t tooth decay rates go up?

When fluoridation is stopped, tooth decay rates do not go up.

There now have been at least four modern studies showing that when fluoridation was halted in communities in East Germany, Finland, Cuba, and British Columbia (Canada), tooth decay rates did not go up.

The dental world has its usual fall guys. The blame game calls out lemons as being one of the culprits at the top of the list along with fruit eating as another, which are the healthiest foods and for both oral health and overall health.

Health professionals more and more believe the sugar from fruit and the acid from lemon are destructive to teeth and should be avoided at all costs, which couldn’t be further from the truth as lemon helps to improve hydrochloric acid in the gut which is needed to keep bad acids from coming up and eroding the tooth enamel causing tooth decay.

Meanwhile, fluoride treatments at the dentist’s office and brushing with toxic toothpastes at home are common practices.

Most people’s body chemistry is highly acidic and substances such as coffee, green tea, kombucha tea and others add to this acidic blood and creates excess unhealthy stomach acid, which in time damages the teeth from the inside out.

Some people avoid processed sugar and their teeth rot and decay, this is because mineral deficiencies, inherited toxins, and poisons from the family line that go back generations and generations play a role in enamel decay.

Most of us come into this world with deficiencies that accumulate and compound over time, and these deficiencies come to fruition in our teeth.

Fluoride is a bandaid and doesn’t address the root cause of tooth decay

Addressing nutritional deficiencies, detoxing inherited toxins, minimising exposure to toxins and improving gut health is the key to healthy teeth and gums.
