What To Look For On A Toothpaste Label

The Front Of The Pack Is An Advertisement. The Back Is The Product.

Every toothpaste on the pharmacy shelf makes the same promises in the same three words. Whiter. Stronger. Healthier. Those words cost the manufacturer nothing and tell you nothing. The ingredients panel on the back - the small grey text most shoppers never read - is where the entire truth of the product lives.

This is not a cynical observation. It is a regulatory fact. In Australia, the overwhelming majority of toothpaste is regulated as a cosmetic under the Industrial Chemicals Act 2019, administered by AICIS (Australian Industrial Chemicals Introduction Scheme). It is NOT assessed as a therapeutic good by the TGA unless it carries a specific therapeutic claim. That means the words on the front of the box were written by a marketing department and reviewed by a lawyer - not approved by a health regulator.

Below is the full decoding method: what each line of the panel means, which actives are worth paying for, and which words are pure noise.

Step 1: Find The Fluoride. This Is The Single Most Important Check.

Fluoride is the most heavily evidenced ingredient in oral care. The World Health Organization lists fluoride toothpaste on its Model List of Essential Medicines. The Australian Dental Association (ADA) and the National Health and Medical Research Council (NHMRC) both recommend fluoride toothpaste for caries prevention. A 2019 Cochrane systematic review (Walsh et al., Fluoride toothpastes of different concentrations for preventing dental caries) found that toothpaste concentrations at or above 1,000 ppm reduce caries in children and adolescents compared with non-fluoride toothpaste, with effect increasing alongside concentration.

So the first thing you do with any tube is find the fluoride line. It appears in two places: in the ingredients list by chemical name, and usually as a ppm figure elsewhere on the box or tube.

The Fluoride Compounds You Will Actually See

What The ppm Number Means

ppm means parts per million of fluoride ion. Adult toothpaste in Australia is typically 1,000-1,500 ppm. Children's toothpaste is deliberately lower - commonly around 400-550 ppm in Australian low-fluoride children's formulas - to reduce the risk of dental fluorosis from swallowed paste during enamel development. Some prescription-strength pastes for high-caries-risk patients run at 5,000 ppm and are dispensed on dental advice.

Step 2: Find The Actives. This Is What You Are Really Paying For.

After fluoride, the actives are the only part of a toothpaste that changes clinical outcomes. Everything else - the abrasive, the humectant, the binder, the flavour - is delivery. Most mass-market toothpaste contains fluoride and effectively nothing else. The tubes worth paying for name their actives on the pack.

Gum And Plaque Actives

Aluminium lactate. An astringent. Astringents contract and tighten soft tissue on contact. In oral care it is used to firm gum tissue, and it is rare in mainstream toothpaste - it is a hallmark of German clinical formulations. If you see it on a panel, the formulator was building a gum product, not a generic one.

Chlorhexidine. An antiseptic with genuine substantivity - meaning it binds to the tooth surface and oral tissues and keeps working after you spit. That property is why chlorhexidine has been a fixture of clinical dentistry for decades. A 2017 Cochrane review (James et al., Chlorhexidine mouthrinse as an adjunctive treatment for gingival health) found chlorhexidine mouthrinse used as an adjunct to mechanical oral hygiene reduced plaque and gingivitis measures compared to placebo. Note the word adjunct. It supplements brushing and interdental cleaning. It does not replace them.

Zinc salts (zinc citrate, zinc lactate, zinc chloride). Zinc binds volatile sulphur compounds - the bacterial gases responsible for oral malodour - and has some plaque-inhibiting activity. If halitosis is your concern, a zinc salt on the panel is a real signal.

Stannous fluoride. Covered above, and worth repeating here: the stannous ion is an active in its own right, not just a fluoride carrier.

Sensitivity Actives

Potassium nitrate. Works on the nerve, not the tooth. Potassium ions accumulate around the dental nerve and reduce its excitability, which is why desensitising pastes require consistent use over days to weeks rather than working on the first brush.

Arginine, and calcium- or strontium-based occluding agents. These work the opposite way - by physically plugging the exposed dentinal tubules that let stimuli reach the nerve. Different mechanism, same target.

If your teeth ache on cold air or cold water, a paste with no sensitivity active in it will not help you no matter what the front of the box says. That is what LACALUT Sensitive is formulated for.

Step 3: The Abrasive System, And Why RDA Matters More Than 'Whitening'

Every toothpaste is abrasive. It has to be - the paste has to physically remove the biofilm and stain that a brush alone smears around. The abrasive is usually hydrated silica, calcium carbonate, dicalcium phosphate, or in some cases alumina.

The measure of how abrasive a paste is, is RDA - Relative Dentin Abrasivity. It is a standardised laboratory index that scores a paste's abrasion against a reference material. Higher RDA means more material removed per brushing stroke.

This distinction is the most commercially exploited gap in the entire category. A high-abrasion paste removes coffee and tea staining quickly, the user sees a visible change in week one, and concludes the paste 'whitens'. It removed a stain layer. That is all it did. And once the extrinsic stain is gone, continued high-abrasion brushing has nothing left to remove except your tooth.

Charcoal pastes are the clearest example. Charcoal's mechanism is abrasion. A 2017 review in the Journal of the American Dental Association (Brooks, Bashirelahi & Reynolds, Charcoal and charcoal-based dentifrices: A literature review) concluded there was insufficient clinical and laboratory data to substantiate the safety and efficacy claims made for charcoal dentifrices, and advised clinicians to counsel patients accordingly. Many charcoal pastes also contain no fluoride.

What To Do With The Abrasive Line

LACALUT's approach in White & Repair is a controlled polishing system rather than a race to the highest possible abrasion. That is a formulation choice, and it is the one you want if you intend to use a stain-removal paste long term.

Step 4: SLS - The Foam, And Who Should Avoid It

Sodium lauryl sulfate (SLS) is a surfactant. It is why toothpaste foams. Foam is not cleaning - it is a detergent creating bubbles - but it does help distribute the paste around the mouth and it is what consumers have been trained to expect from a toothpaste.

SLS is not dangerous, and the recurring internet claim that it is carcinogenic is NOT supported by evidence. But there is a real, narrower issue: SLS has been associated with irritation of the oral mucosa and with aphthous ulcer (recurrent mouth ulcer) frequency in susceptible individuals. The literature is mixed - studies are small and results inconsistent - but the pattern is consistent enough that it is standard clinical advice to trial an SLS-free paste if you get recurrent aphthous ulcers.

Step 5: The Words That Mean Absolutely Nothing

Some words on a toothpaste box are legally controlled. Most are not. Here is the honest split.

The rule that follows from this table is simple. Any claim you cannot verify against the panel or a citation is not a claim - it is decoration. The panel is the contract. The front is the pitch.

Why Australian Toothpaste Regulation Makes This Your Job, Not The Regulator's

This is the part most articles skip, and it is the reason the whole exercise matters.

Australia splits oral care into two regulatory buckets. A product making a cosmetic claim - cleans teeth, freshens breath, removes stains, helps reduce plaque - is an industrial chemical product and sits with AICIS. A product making a therapeutic claim - treats, cures or prevents a disease - must be assessed by the TGA and carry an AUST L or AUST R number.

Almost all toothpaste sold in Australian supermarkets and pharmacies sits in the first bucket. There is nothing improper about that. But the consequence for you as a shopper is direct: nobody at a regulator pre-approved the words on the front of that box. There is no gatekeeper checking that 'advanced' means anything. The only thing that has been checked is the ingredients declaration. So that is what you read.

You are standing in the aisle. You have a tube in your hand. Do this, in order.

What A Gum-Focused Panel Actually Looks Like

Applying the method to a real product makes it concrete. LACALUT Aktiv is a German formulation from a brand founded in 1925, and its panel names three things that matter:

That is a panel built for a specific job: it is formulated for people with bleeding, inflamed gums, and it is designed to help reduce the plaque that drives the problem. Compare that to a generic paste whose panel lists a fluoride, an abrasive, a humectant, a foaming agent and a flavour - and nothing else. Both are toothpaste. They are not the same product.

If bleeding gums are why you are reading this, start with What Causes Bleeding Gums, then read Can Gum Disease Be Reversed? for what the evidence actually supports.
