"Read your toothpaste label like a food label. The ingredient I'd flag is SLS the foaming agent in most brands which research associates with irritation of the mouth's soft tissue. It's why I rate Gutology: SLS-free, gentle on the mouth, and Truebiotic technology to support the oral microbiome."
Dr Seb Lomas - Biological Dentist
Finally a toothpaste that cleans your teeth and works with your mouth, not against it. That fresh, just-brushed clean without SLS, the harsh foaming agent research associates with gum irritation. Gentle on gum tissue, 99.9% natural, and powered by hydroxyapatite

When it comes to cavities and gum diseases the bacteria in your mouth are as important as brushing your teeth.
Supports a natural oral microbiome with ingredients you can use everyday.
Formulated with natural hydroxyapatite a biomimetic mineral shown in lab studies to restore enamel-like surfaces by replenishing calcium and phosphate.
Powered by clinically studied ingredients designed to support enamel strength and oral microbiome balance, without unnecessary additives.
Free from SLS and aggressive surfactants. Formulated to support your oral microbiome - never disrupt it.
Your oral microbiome plays a key role in how your breath smells. Supporting that ecosystem helps you feel fresher, without masking.
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.
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
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.
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.

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.

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).
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.
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.
