Hydroxyapatite

Microbiome Friendly

Fluoride Free

"Hydroxyapatite has been studied in lab and clinical settings for its role in enamel remineralisation. That’s why I often suggest sticking with it for at least 3 months to build a consistent routine."

Gutology Hydroxyapatite Toothpaste 120ml

£16.00

99.9% natural, SLS-free toothpaste powered by hydroxyapatite to support enamel strength and a balanced oral microbiome.

It's a fair question and a growing area of research. The ingredient under scrutiny is SLS (sodium lauryl sulfate), the synthetic detergent that makes most toothpaste foam. Research associates SLS with irritation of the mouth's delicate soft tissue. Gutology is formulated without it.

Because we built it around hydroxyapatite the mineral your enamel is naturally made of, studied for supporting and protecting the tooth surface. For people who'd rather skip harsh detergents, it's the gentle alternative.

Yes. Gutology is SLS-free and formulated to be gentle on the mouth's soft tissue, with a low-foam, naturally-derived clean. No harsh detergents or synthetic surfactants.

Yes just gently. Instead of SLS, the harsh foaming agent research associates with soft-tissue irritation, Gutology uses a naturally-derived surfactant. A light, pleasant lather and a smooth, just-brushed feel.

Most natural toothpastes stop at what they leave out. Gutology Mint Toothpaste is 99.9% natural, SLS-free and powered by hydroxyapatite. Clean ingredients, with proof they work in harmony with your mouth.

The Oral-Gut Connection

Your mouth is the gateway to your microbiome. Brushing isn’t just cosmetic it’s a daily ritual that supports the balance your body depends on.

What the research says about SLS and your gums

SLS (sodium lauryl sulfate) is the detergent that makes most toothpaste foam. Its effects on the soft tissue of the mouth have been studied for decades. Clinical studies found SLS-containing toothpaste was associated with a higher frequency of oral ulceration than SLS-free alternatives, while later reviews concluded SLS-free toothpaste may benefit people prone to recurrent mouth ulcers.

SLS is an approved cosmetic ingredient. But if the soft tissue in your mouth feels sensitive, it's a reasonable ingredient to question. Gutology is formulated without it

It's not just the tissue it's the balance

Healthy gums depend on more than the surface of your mouth. Research increasingly links a balanced oral microbiome to gum health, and suggests harsh, broad-acting ingredients can disturb that balance rather than support it.

That's why Gutology is formulated differently: with TrueBiotic® a postbiotic (from Lactobacillus plantarum HEAL19) studied in laboratory settings for supporting microbial balance and without SLS.

Independently lab-tested and certified KIND TO BIOME®, confirming it maintains the microbiome balance of a healthy oral cavity.

The Power of Hydroxyapatite

Hydroxyapatite is a biocompatible mineral that closely reflects the natural structure of enamel.

It helps support a more balanced, mineral-rich surface environment without disrupting the oral microbiome.

Sometimes, science feels a little like magic.

This is more than just cleaning

Gutology Mineral Toothpaste cleans your teeth effectively with a microbiome-friendly formulation.

Frequently Asked Questions

Have concerns? That’s okay. You can find all your urgent answers right here.

Is this toothpaste worth the price?

Absolutely and here’s why:

At 120ml, Gutology’s toothpaste is significantly bigger than many leading natural alternatives, which often come in 75ml tubes. That means more value per use.

We use biomimetic hydroxyapatite a fluoride-free mineral that mirrors the natural structure of enamel and is studied for its role in supporting surface mineral balance.

Stick with it and save. Our subscription model rewards consistency with better pricing no commitment, cancel anytime.

Is this toothpaste suitable for children?

Yes! Gutology toothpaste is 100% safe for children, thanks to its gentle, fluoride-free formulation. Instead of fluoride, we use biomimetic hydroxyapatite — a clinically proven mineral that helps rebuild and protect tooth enamel, without any risk if swallowed.

It’s also free from harsh foaming agents (like SLS), artificial sweeteners, and synthetic preservatives, making it ideal for growing smiles and sensitive mouths.

For little ones, we also offer a naturally flavoured strawberry version — making brushing time a whole lot easier (and tastier).

Do you test for heavy metals?

Your health is our priority. Every batch is independently tested for heavy metals using ICP-MS (Inductively Coupled Plasma Mass Spectrometry)— one of the most advanced and sensitive detection methods available.
We test for critical elements including lead, arsenic, mercury, and cadmium, all of which are consistently below detectable limits.
We also screen for other trace elements such as nickel, chromium, cobalt, and zinc— and confirm that all results fall well within the EU and UK’s strict safety thresholds for daily exposure.
These results are reviewed by our quality team to ensure the highest standards of purity and safety.

Is this product vegan and cruelty-free?

Yes, this has been requested by many nutritionists that we work with. We've achieved this by using a vegetable sourced glycerine in our formulation. It is also 100% cruelty-free.
