Fluoride has the strongest evidence of any toothpaste ingredient for reducing tooth decay. Going without it is a legitimate personal choice, but it is a trade-off rather than a free upgrade, and it should be a deliberate decision made with your dentist rather than an accident of picking up a nice-looking tube.
Walk the natural aisle and a lot of what's there is fluoride-free. It's often not on the front in large letters, and plenty of people buy it without realising.
This article isn't here to talk you into or out of it. It's here so the choice is actually a choice.
What toothpaste is doing
Three separate jobs, and they get conflated:
Cleaning. Done by the abrasive — usually silica or calcium carbonate — plus the brushing itself. Every toothpaste does this, fluoride or not. Most of the cleaning is the brush.
Decay resistance. This is the fluoride job. Fluoride works by helping remineralise enamel and making it more resistant to acid.
Everything else. Freshening, foaming, whitening, gum feel, flavour. Nice, but not the main event.
A fluoride-free toothpaste does the first and third jobs. It does not do the second.
What the evidence actually says
Fluoride in toothpaste is one of the better-established findings in public health. It's endorsed by the Australian Dental Association, the National Health and Medical Research Council, and the World Health Organization, and it's the reason water fluoridation exists in most of Australia.
That's not a marketing position, and it's worth being straight about it even in an article on a natural brand's blog.
Why people choose fluoride-free anyway
Real reasons, not silly ones:
- Children who swallow toothpaste. Fluorosis from swallowing fluoride toothpaste in early childhood is a genuine consideration, which is why children's pastes have lower concentrations and why supervision is advised.
- Already getting fluoride elsewhere — fluoridated water plus mouthwash plus toothpaste, and someone would rather reduce the total.
- Sensitivity or reaction to a specific formulation.
- A general preference for fewer synthetic actives, which is a values position and doesn't have to be justified on clinical grounds.
If any of those is you, fluoride-free is a reasonable choice. Just make it knowingly.
What natural toothpastes use instead
- Xylitol. A sugar alcohol that oral bacteria can't ferment. Has some evidence behind it, though not on fluoride's scale.
- Calcium compounds, sometimes positioned as supporting remineralisation.
- Propolis, tea tree, myrrh, neem. Traditional oral-care ingredients with long histories of use.
- Bicarbonate, as a mild abrasive and for pH.
- Charcoal. Worth flagging: charcoal pastes can be abrasive enough to wear enamel over time, and abrasion doesn't grow back.
Other things worth checking on a natural tube
Fluoride isn't the only variable, and some "natural" pastes still contain things people are trying to avoid:
- SLS (sodium lauryl sulfate) — the foaming agent, and a common irritant for people who get mouth ulcers
- Artificial sweeteners
- Titanium dioxide, used for whiteness
- Very high abrasivity, especially charcoal and some whitening pastes
How to decide
Three questions:
- Are you getting fluoride from anywhere else? Fluoridated tap water covers most of Australia.
- What's your decay history? Someone who's never had a filling is in a different position from someone with recurring decay.
- Have you asked your dentist? They know your teeth. An article doesn't.
That third one isn't a cop-out. Decay risk is individual, and it's the whole basis of the decision.
OGA's propolis toothpaste is a 110g fluoride-free natural toothpaste with propolis, eucalyptus and xylitol. It's a natural daily oral care product, and if you're weighing up fluoride, that's a conversation for your dentist rather than for a tube.
Frequently asked
Is fluoride-free toothpaste okay? It's a legitimate personal choice, but it's a trade-off. Fluoride has the strongest evidence of any toothpaste ingredient for reducing decay, so going without means giving that up. Your decay risk and whether you get fluoride elsewhere both matter.
What is the healthiest toothpaste? There's no single answer. The ingredient with the most evidence behind it is fluoride. Beyond that it depends on your own teeth, your sensitivity, and what you're trying to avoid.
Does natural toothpaste clean as well? Cleaning comes from the abrasive and the brushing, and natural toothpastes do that. The difference is decay resistance, which is fluoride's job.
Is charcoal toothpaste safe? Some charcoal pastes are abrasive enough to wear enamel with long-term use, and enamel doesn't grow back. Check the abrasivity and ask your dentist.
What does xylitol do in toothpaste? It's a sugar alcohol that oral bacteria can't ferment into acid. It has some supporting evidence, though not at the scale of fluoride's.
OGA Propolis Toothpaste is a 110g fluoride-free natural toothpaste made in Australia with propolis, eucalyptus and xylitol. It is a cosmetic oral care product and is not intended to diagnose, treat or cure any condition. For advice on fluoride and your own decay risk, speak to your dentist.
