KIND TO BIOME® certification mark
WORLD'S FIRST

The mouth is the gateway to your gut

The world's first KIND TO BIOME® certified toothpaste. 98.7% natural, SLS-free, and powered by hydroxyapatite to support enamel and your oral microbiome

  • Independently lab-tested by QACS Ltd Laboratories
  • Maintains the microbiome balance of a healthy oral cavity
  • A world first no toothpaste had earned this certification before

The natural toothpaste that works.

  • Microbiome-friendly

    Did you know? Your child’s mouth hosts over 700 species of bacteria some helpful, some not so much. Supporting microbial balance is a key part of caring for developing mouths and encouraging healthy brushing habits from an early age.

  • What if my child swallows some toothpaste?

    It’s normal for young children to swallow small amounts of toothpaste while learning to brush. That’s why Gutology Kids is fluoride-free and made with gentle ingredients designed for daily use in growing mouths.

  • Fluoride-Free

    Many parents choose fluoride-free options with hydroxyapatite a mineral studied for how it supports and protects enamel over time.

  • Not all toothpastes are created equal

    Many high street toothpastes include foaming agents that may disrupt the oral microbiome. Gutology Kids is made with gentle ingredients and no harsh additives.

  • Bad breath?

    Your oral microbiome plays a big role in how your breath smells and keeping it balanced is an important part of everyday oral care.

  • Gentle on teeth and gums

    Free from harsh chemicals, artificial flavours, and colourings made with gentle ingredients that respect the needs of growing mouths.

We've been doing oral care backwards

The problem was never bacteria it was the war on them.

Your mouth is home to hundreds of bacterial species, and research increasingly links oral health to keeping that ecosystem in balance.

For decades, oral care focused on killing bacteria, but broad antibacterial products can disrupt the good bacteria alongside the bad. Gutology takes a different approach: not antibacterial but probacterial. SLS-free and certified KIND TO BIOME®, it's designed to work with your mouth's microbiome, helping maintain the balance of a healthy oral cavity.

Join the revolution

It took us 5 years to create a mineral toothpaste loved by both parents and dentists. While most oral care companies overlook the role of the oral microbiome, Gutology Kids is formulated with microbiome-friendly ingredients giving little ones an effective choice for healthy, happy smiles.

Why TrueBiotic® matters?

TrueBiotic® technology is designed to work in harmony with the natural biology of children’s mouths.

It supports a balanced oral microbiome, which plays an important role in maintaining a healthy environment for teeth and gums.

Gentle and science-backed, it’s a smart choice for growing smiles.

This is more than just cleaning

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

Directions

Gutology Toothpaste:
  • Brush twice daily as you would with regular toothpaste.
Gutology Liquid Biome+:
    1. Measure & Mix
      Combine 1.5ml of Liquid Biome+ with 10ml of water using the included cup.
    2. Swish
      Swish the mixture thoroughly around your mouth for 30 seconds.
    3. Release
      Spit out the mixture into the sink.
      Do not rinse with water afterwards — this allows the prebiotics and hydroxyapatite to keep working for longer-lasting benefits.
Floss:
  • Break off about 30 cm, wrap around your fingers, and gently glide between teeth near the gums.
Tongue Scraper:
  • Place on your tongue, gently scrape forward, wipe clean, and repeat. Wash and dry after use.

Frequently Asked Questions

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

Is this toothpaste worth the price?

We think so. Gutology Kids is formulated with hydroxyapatite the same mineral found in natural enamel and TrueBiotics®, a postbiotic ingredient studied for how it supports microbial balance in the mouth. Every tube is designed with gentle, microbiome-friendly care in mind.

Does this toothpaste have artificial flavourings?

No we don’t use any artificial flavourings. The gentle strawberry flavouring is naturally inspired, making brushing more enjoyable for kids without the need for synthetic additives.

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.

What if I need more help?

We understand that digestive issues can be complex, that's why we offer a £75 voucher towards advanced microbiome testing to every DigestBox customer.

Black spots inside the toothpaste cap

Inside the cap black moulding starts to appear on every paste about 2 weeks after opening. My son constantly asks me why it’s happening but I have no answer for it. I’ve tried three pastes so far and all of them had the same issue. We had to stop using it.

Excellent product

My granddaughter who is 4 years old came to stay and used the strawberry kids toothpaste and she loved it, in fact she cleaned her teeth 3 times which is unknown to get her to clean once! It’s been a hard battle to get her to like any toothpaste so very pleased and will certainly be buying it again. I would like to know at what age a child can use it as I have another granddaughter who is 9 months but has teeth!!

Strawberry toothpaste

My little boy loves this because it doesn’t foam up like other toothpastes do which annoys him. His teeth already look much whiter.

My daughter loves it. She doesn't really like brushing as her teeth start getting wobbly, but since we use gutology she is much more keen to do it. Thank you

My grandson is 7 months old with 1 tooth & hasn't expressed an opinion!
However, his mother ordered the same thing - so I know I did right! :)

Amazing toothpaste for all dental issues

Quite literally amazing toothpaste!
I tried it as my daughter has been having issues with early cavities- several dark lines in the fissures of her molar.
I hoped this would help as everything the dentist has given us is making things worse.
4 weeks in her gums are no longer inflamed and the dark areas on her tooth are 50% less. After 8 weeks they have almost gone.
My daughter is a mouth breather at night and used to have awful breath in the morning but that too has gone!
I cannot reccommend this product enough it really is amazing

Amazing!

I thought I'd test gutology before I gave it to my autistic son. Gums and teeth feel healthy (they didn't before....gum disease🙄) staining dramatically reduced after 2 weeks. Smooth feel of tooth surface that lasts all day..wow! My son is a trickier customer but hasn't outright refused. I bought the adult one within a week, I think it might be worth it for my family's oral health.

No horrible taste

Finally I've found something my 10 year old will use.

I've tried every other fluoride toothpaste going and she hates the taste. This she has happily accepted.

I've also now swapped myself to the adult one

Disappointing

I was really looking forward to trying this toothpaste brand. Unfortunately I am disappointed with the results. My youngest son who is 2 has weak enamel and I was hoping this would help. Unfortunately the condition of his teeth rapidly deteriorated after using this toothpaste for a month, leaving one tooth brown and eroded. All 3 of my children liked the taste but I won’t be buying again.

Mixed reviews from the kids

I have a 10 year old and a 5 (almost 6) year old. The 10 year old says it's disgusting, tried it and immediately spat it out and changed to the toothpaste that was in use previously. The 5 year old loved it and is now spitting the toothpaste (we had a toothpaste that was edible). So... mixed reviews. I personally quite like that it has hydroxyapatite and no fluoride, as my kids have never used fluoride containing toothpaste and their teeth are absolutely perfect, so I don't see the point.
