A Natural Alternative to Fluoride in your Toothpaste

The Positive Revolution...


As a Frenchman, from my perspective, the French and Brits may be neighbours, but often seem to move in opposite directions – We are joined by a tunnel, yet drive on opposite sides of the road (a completely life threatening concept, but hey, who is right?) … And more importantly, who will change their driving habits to meet the other?– neither of course!

And then there is tea and coffee – the British being highly particular about their tea (often enjoyed with scones) whilst the French taking pride as connoisseurs of the coffee and croissant. – And let's not even start on football…

We choose different approaches right down to the water we drink from our taps! The French fluoridate their drinking water, and the Brits don’t. Ok, so here I am, a French guy, who openly admits to taking the British side on this point, which has led to a ‘Positive Revolution’ in oral hygiene. I simply said “non” to fluoride.

Fluoride is found naturally in water, soil and food. It is the ionic form of fluorine, the thirteenth most abundant element in the earth’s crust, and is released into air and water naturally; water being the main dietary source of fluoride, where it is found in varying quantities. In nature, in small quantities there are some great benefits. Exposed to high doses of synthetically produced fluoride, it acts as a neurotoxin, and is potentially dangerous. (Fluorine, by the way, is a highly toxic and reactive gas.) Natural calcium fluoride with low solubility and toxicity from ingestion is distinct from fully soluble, toxic, industrial fluorides. The toxicity of fluoride is determined by environmental conditions and the positive cations present.1

If there is tons of fluoride in Nature already, that’s probably enough, and let’s not add synthetic fluoride to our toothpaste. I will not fight against fluoride, but if toothpaste can be made without it, and still demonstrates the same anti-cavity benefits, then I definitely prefer that route. 


Continual exposure to high quantities of synthetic, manufactured fluoride (through water fluoridation, dietary supplements and toothpaste), is linked to a number of health issues, including dental and skeletal fluorosis, thyroid, and neurological problems, as well as possibly contributing to a raft of other complications. Acne, cardiovascular arteriosclerosis, arterial calcification, myocardial damage, heart failure, osteoarthritis, bone cancer, lower fertility, and early puberty in girls all have a potential link to fluoride.2 - And then there has been an ongoing debate from 2012 suggesting Fluoride overuse can be associated to a lower IQ. To date, 68 studies show this connection.3,4,5,6 


So how do we actively make a change for the better? We wanted to make a positive difference to our planet and all the people in it by creating an all natural solution for oral hygiene, good for people and good for the planet. 


It all started with some very cool research I discovered on kids enjoying liquorice lollipops to help fight plaque and tooth decay! The study showed a decline in S.Mutans (bacteria which aid tooth decay) in children who were given liquorice lollipops twice a day for a period of 22 days7, over the unfortunate group who weren’t. I felt really inspired by it, and found it amusing that a sweet  could prevent cavities. Hey, what if you could brush your teeth with liquorice? Sticking to toothpaste and not sweets, I decided to add liquorice oil to our dental formula.


Tooth decay is created from a bacteria named streptococcus mutans and also various lactobacilli. Imbalanced pH levels can create an environment for these bacteria to thrive. Licorice root contains a compound called glycyrrhizin, which can effectively combat these harmful bacteria and help reduce tooth decay.9  Studies have also revealed other bioactive ingredients such as, Licoricidin and Licorisoflavan-A, and licochalcone A found in dried liquorice root, and liquorice extract act as effective antibacterial agents that can prevent or reduce the growth of bacteria connected with tooth decay and oral diseases.9&11


I realised that liquorice has a very particular taste; some kids love it, but as a child, I wasn't a fan. So I decided to neutralize the taste slightly by blending other herbal compounds such as peppermint, anise, eucalyptus and sage (See our list of ingredients here!). We wanted our Dental formula to provide fresh breath and taste great as well as offering the sound dental benefits of preventing bacterial growth and reducing inflammation. I guess you could say it was a bit like the excitement you get out of making up a new recipe, and thinking precisely and carefully about how you would like the end taste to be. We also included charcoal which is a great all naturally soft, abrasive whitener to give you that really pure, sparkly smile!


We spent two years of dedicated research and analysis, where we documented our research derived from scientific publications and articles about the benefits of liquorice. We also commissioned scientific experts to run a formalized in vitro study to confirm the efficacy of NOICE Toothpaste in reducing the bacterial growth of plaque, and in so doing reducing the likelihood of cavities and oral disease. The results conclusively proved that NOICE Toothpaste demonstrated a clear antimicrobial effect, achieving a statistically significantly greater reduction in biofilm growth.9 In addition, all tests were cruelty free, and laboratory testing did not involve animals. We were delighted to be able to use a natural substance to fight plaque and cavities, that has the added benefit of being free from adverse health risks.


Since creating our NOICE Toothpaste from natural ingredients, there has been more and more research highlighting the positive effects of liquorice. Our team is really excited to see this, and  the general trend towards promoting the dental benefits of liquorice
