Welcome to Byrdie UK's Wellness Week. Over the next seven days, you'll get to read about how to make your body, mind and, well, your life more balanced. We know it's not January, but wellness has become an all-year-round focus for many, and with autumn on the way (read: cold and flu season), now seems like a good time to talk about not just keeping well but boosting our wellness from all angles. From the best tech to improve your health to the small tweaks anyone can do to bring you more happiness, we've thought about everything you might want to factor a little more wellness into your life with ease. Today, we have two dentists debating the pros and cons of fluoride-free toothpaste.Girlfriend Collective
Have you ever thought about switching to fluoride-free toothpaste? I have. Mostly when I had acne and found myself down a Google black hole, reading on forums that people were blaming fluoride for their hormonal breakouts. Fluoride is used in toothpaste to strengthen the teeth and prevent cavities. Despite murmurs that fluoride is bad for our health (it's been linked to everything from kidney stones to cancer), there's little concrete evidence out there to corroborate the need to switch to fluoride-free toothpaste. To try and get to the bottom of it, I spoke to two dentists to find out whether we should make the switch. I also sent them the ingredient lists for three alternative fluoride-free toothpastes to review.

Harvey Grahame, BDS, clinical director at Smilepod.co.uk, isn't convinced by fluoride-free toothpaste, and that's putting it mildly: вЂњI am really skeptical of these expensive, beautifully packaged products that have little or no science behind them. They have removed all the active ingredients responsible for the huge improvements we see in dental health and replaced them with exotic sounding oils!вЂќ
According to Grahame, when the bacteria in dental plaque reacts with the sugar in our diet, it produces acid that is damaging to the teeth and enamel. Fluoride is added to toothpaste to strengthen the teeth, thus preventing potential damage.
вЂњIn theory, if we ate no sugar and kept our teeth 100% plaque-free, there would be no need for fluoride in our toothpaste, as there would be no bacteria or food to cause damage,вЂќ says Grahame. вЂњIn practice, this does not happen, which is why there has been around a 25% reduction in the levels of dental decay since the introduction of fluoride toothpaste.вЂќ
I sent Grahame the ingredient list for the three fluoride-free toothpastes by brands Lebon, Buly and Aesop (pictured above). Unsurprisingly, the feedback wasn't positive. вЂњThey probably taste great and have a wonderfully exotic list of ingredients, but I am really struggling to say anything positive about them other than, having googled them, they have great boxes!вЂќ
If you're set on making the switch to fluoride-free regardless, of the three options, Grahame preferred Aesop's offering, вЂњIt has a detergent and active ingredients that will stop plaque redeveloping, possibly reduce gum inflammation and remove stains.вЂќ
On the flip side, Giacomo Favero, cosmetic dental surgeon, clinician and researcher, isn't convinced fluoride is great for our health. вЂњFluoride in toothpaste is a chemical mixture that contains a wide array of chemicals, putting this substance in category 4 of the hazardous materials scale. This is the highest and most dangerous rating a substance can receive.
вЂњFluoride is believed to be useful to protect against dental cavities, but if we look at the science on fluoridation, there are many controversies. And the research on fluoride is mixed as far as the benefit. If you look closely at the studies, and you combine them all together, I am convinced that if there is a benefit, it's no longer there, in part because we're ingesting too much fluoride.
вЂњWe're getting two to three times more than what is written in the toothpaste dosage direction; dosage should be the size of a pea. Too much fluoride can cause dental (discolouration of teeth) and skeletal fluorosis (dense, brittle bones),вЂќ adds Favero. вЂњCustomers are increasingly looking for less harmful products, and it's about time the industry delivers.вЂќ
Interestingly, Favero suggests that our dental problems can also be indicators of wider health issues. вЂњStress can affect dentinal and salivary flow with over-production of cortisol. Hormonal shifts such as low thyroid activity, pregnancy, teenage years, and growth spurts in children can affect dentinal and salivary flow and make teeth susceptible to decay,вЂќ he says.
Both Grahame and Favero make good cases for and against fluoride, so what to do? Favero believes, in some cases, fluoride toothpaste should be used. вЂњIndividuals who experience early stages of decay, or who have cavities forming, should be sure to have daily exposure to topical fluoride using only a pea dose, and they must not swallow it,вЂќ he says.
I'm personally one of those people who, despite how much I brush and floss, grows plaque like it's going out of fashion. I need the fluoride to help protect my teeth, but I've been introducing these fluoride-free toothpastes a few times a week just to try and reduce my fluoride intake.
Lebon Sweet Extravagance Toothpaste (with rose, orange blossom and mint) tastes incredible, while the Aesop and Buly offerings taste good and look incredibly chic. If you're not prone to plaque and never need fillings, you could make the switch and see how you get on. While the dentists disagree on the use of fluoride, they are aligned that the Aesop toothpaste offers the best combination of ingredients, making it a good place to start.
