SLS-Free Toothpaste: Do We Really Need All That Foam?

SLS-Free Toothpaste: Do We Really Need All That Foam?

We’ll happily spend twenty minutes researching a face serum.

We check the ingredients in our cleanser. We know whether our shampoo is sulfate-free. We compare moisturisers, sunscreens and hair masks.

Then, twice a day, many of us reach for toothpaste without giving the ingredient list a second thought.

But oral care is starting to get the same attention as skincare — and one ingredient you may have noticed people talking about is SLS.

If you’ve been searching for SLS-free toothpaste in Australia, here’s what it actually means, why toothpaste foams in the first place, and why some people prefer a lower-foaming formula.

What is SLS in toothpaste?

SLS stands for sodium lauryl sulfate.

It is a surfactant used in many personal-care products, including toothpaste.

One of the things you notice most when using an SLS-containing toothpaste is the foam.

And because we’ve grown up associating lots of bubbles with “clean”, it can feel as though the more a toothpaste foams, the better it must be working.

But foam and cleaning are not the same thing.

SLS helps ingredients spread around the mouth and contributes to the familiar lathering sensation of conventional toothpaste.

That doesn't mean every toothpaste needs to foam heavily.

Why are people choosing SLS-free toothpaste?

For most people, using toothpaste containing SLS isn't automatically a problem.

But SLS has been investigated in relation to oral irritation and soft-tissue effects in some individuals.

A 2022 review reported that SLS-containing oral-care products have been associated in the literature with effects such as oral mucosal irritation, inflammation and desquamation. The authors also noted differences between formulations and individual responses.

SLS-free toothpaste has also been researched in people who experience recurrent aphthous ulcers — commonly known as mouth ulcers. A systematic review found some favourable findings for SLS-free toothpastes, although the available evidence had limitations.

So this isn't about declaring SLS “bad”.

It's about recognising that not everyone wants or enjoys the same brushing experience.

Maybe your toothpaste doesn't need to feel so intense

There is a funny adjustment period when you first switch to a low-foaming toothpaste.

You start brushing and think:

Where are all the bubbles?

Then you realise something.

Your mouth doesn't need to feel like it has been filled with foam for you to brush thoroughly.

A lower-foaming toothpaste can feel softer and more considered — especially if you already prefer skincare and personal-care products that take a more minimalist approach.

For us, toothpaste shouldn't need to feel aggressive to feel effective as part of your daily oral-care routine.

Why Restore is SLS-free

When we created Restore, we didn't begin with the question:

“How do we make another conventional toothpaste?”

We started with:

“What would we actually want to use ourselves every morning and every night?”

That meant looking carefully at both what went into the formula and what didn't.

Restore was intentionally formulated without SLS and with a lower-foaming brushing experience.

The aim wasn't to make toothpaste feel medicinal.

It was to make everyday oral care feel considered.

Something that belonged beside your skincare rather than hidden in the bathroom drawer.

What does SLS-free toothpaste feel like?

If you've only ever used traditional high-foaming toothpastes, an SLS-free formula can feel different at first.

You may notice:

less foam while brushing
a creamier texture
less of the “mouth full of bubbles” sensation
a brushing experience that feels a little more subtle

None of these things automatically tells you whether a toothpaste is right or wrong for your individual oral-health needs.

They're simply differences in formulation and experience.

And sometimes that experience is exactly why people make the switch.

Is SLS-free toothpaste better?

We don't think toothpaste needs to be divided into “good” and “bad” ingredients quite that simply.

For many people, SLS-containing toothpaste is well tolerated.

For others, an SLS-free formula may simply be their preference.

The more useful question is:

What works for your mouth, your preferences and your individual oral-health needs?

That is a much more sensible way to approach oral care than assuming one formulation is universally best for everyone.

What else should you look for in toothpaste?

SLS is only one part of a much bigger formulation.

When you're comparing toothpastes, it's worth looking at the whole product rather than one ingredient on the front of the box.

Consider things such as:

the active or functional ingredients
abrasivity
flavour
foaming agents
how the toothpaste feels during brushing
your individual caries risk
sensitivity
gum health
recommendations from your own dental practitioner

For people specifically looking for a fluoride-free option, the type and concentration of alternative ingredients may also be something they want to understand.

Restore contains nanoXIM™ nano-hydroxyapatite as part of its formulation and is designed for people who have chosen a fluoride-free oral-care option.

Oral care is having its skincare moment

Perhaps this is the bigger conversation.

For years we've approached skincare with curiosity.

What is this ingredient?

Why is it here?

Does this formula suit me?

Do I actually enjoy using it?

There's no reason we can't ask the same questions about toothpaste.

After all, this is something most of us use every single day.

Morning.

Night.

Again tomorrow.

And again the day after that.

So maybe choosing your toothpaste deserves a little more thought than simply grabbing whichever tube happens to be on special.

Not because you need to fear ingredients.

But because considered oral care starts with understanding what you're using.
