Will I get cavities without fluoride?
Short answer: fluoride isn't the only way to protect enamel. Gutology is powered by hydroxyapatite one of the most researched fluoride-free ingredients in oral care, and the same mineral your enamel is naturally made of. It's studied for binding to the tooth surface and supporting remineralisation, leaving teeth feeling smooth and clean. It's how thousands have switched to fluoride-free without the compromise.
-
Does it foam?
Yes just gently. Instead of SLS, the harsh synthetic foaming agent in most toothpastes, Gutology uses a naturally-derived surfactant. So you still get a light, pleasant lather without the irritation SLS can cause to gums and soft tissue. You'll finish with that smooth, just-brushed feel: a clean you can feel, minus the heavy foam.
-
Does it whiten teeth?
Yes gently and naturally. Gutology's hydroxyapatite works by smoothing the enamel surface and filling in micro-defects, which increases the appearance of whiteness over time. It's a gradual, natural brightening your teeth's own colour enhanced not a harsh chemical bleach.
-
Is this safe for children?
Yes and it's a popular choice for families. Because Gutology is fluoride-free, it avoids the swallowing concerns associated with fluoride toothpaste, and it's suitable from ages 3+. For younger brushers, we also make a strawberry kids' version same SLS-free formula, in a flavour they'll actually look forward to.
-
How is Gutology different from other natural toothpastes?
Most natural toothpastes stop at what they leave out. Gutology Mint Toothpaste is 99.6% natural, SLS-free and powered by hydroxyapatite. Clean ingredients, with proof they work in harmony with your mouth.

Gutology was a very easy swap for us as a whole family, I love that I know I am improving my gut health with each brush every day!
-
As a biological hygienist, I scrutinise every ingredient and Gutology is the first toothpaste I've confidently recommended to my patients, used myself, and given to my son.
-
I recommend this to my patients because I believe in what's inside it, and hydroxyapatite is a big part of that. It's the mineral our enamel is actually made of, and it's at the heart of what Gutology does.
-
As a nutritionist, I am always looking for ways to support my own gut as well as my clients'. That's why I use Gutology, it cleans my teeth and mouth without destroying beneficial bacteria and supports my gut microbiome too.
-
My little one absolutely loves brushing her teeth now and loves the taste of her toothpaste! Thank you Gutology!

Independent experts view
The oral microbiome matters
For decades, oral care had one goal: kill bacteria. That thinking is changing. Your mouth is a living microbiome, and the balance of good bacteria is what keeps it healthy. Protecting that balance, rather than stripping it, is where modern dentistry is heading, the same shift we already made with gut health
I believe this is the biggest change in oral care in a generation. The evidence is clear: work with the mouth's microbiome, not against it. That's why I recommend a probacterial approach like Gutology.

-
Will I get cavities without fluoride?
Fluoride isn’t the only way to care for your enamel. Ours is made with non-nano hydroxyapatite, from the same mineral family as your enamel, to help strengthen it. In laboratory testing, up to 65% of the surface hardness lost to acid came back. Kind to Biome® certified and 99.6% natural origin, it cleans without stripping your good bacteria.
-
Does it foam?
Gently. We use a coconut-derived cleanser instead of SLS, so expect less froth and the same clean.
-
Can my kids use it?
From age 3. For under-3s, try our Hydroxyapatite Kids Toothpaste
-
How long does a tube last?
About 2 months for one person brushing twice a day.
Gutology was one of the easiest swaps I made. No fluoride, no nasties, and it actually supports your oral microbiome. Feels good to know every little change is adding up.
