Our Editorial Standard
Every product in our directory is evaluated using the Modern Holistic Living Standard. We assess materials, ingredient transparency, long-term durability, everyday practicality, replacement availability, manufacturer consistency, and overall value before including any recommendation. We only feature products we would calmly recommend to our own families.
Editorial
Why we recommend it
- Glass packaging is rare in toothpaste — Truthpaste has committed to it from the start rather than treating it as a marketing detail.
- The formula is built around food-grade bentonite clay, organic coconut oil, and essential oils, with a short and fully disclosed ingredient list.
- No synthetic flavor system, no artificial sweeteners, no foaming agents, and no preservatives beyond what the botanical ingredients require.

- Simple, fully disclosed formulation with named botanical flavor
- SLS-free and titanium-dioxide-free by design
- UK-made small-batch producer with published sourcing
Cons
- Jar format requires a clean brush and a spatula for the finicky
- Higher unit price than tube pastes
- Fluoride-free base version — check the range for the hydroxyapatite SKU

Who it suits
Best for
- 01
Households already using refill-format personal care
- 02
Users who prefer a traditional clay-based paste over gel textures
- 03
Small households where a jar lasts a reasonable rotation window
Transparency
Things to know
- 01
The texture is dense and earthy — closer to a paste than a gel. Many users adjust within a few uses.
- 02
Does not foam. Foaming is a marketing expectation, not a cleaning requirement.
- 03
Use a wooden or ceramic spoon to scoop rather than a metal one — metal can react with bentonite clay.
- 04
Fluoride free. Evaluate against your dental provider's guidance.

Inside the tube
Ingredients & formula highlights
Coconut oil
A long-standing oral-care ingredient prized for its mild antimicrobial profile and ability to carry essential oils evenly through the paste.
Wintergreen essential oil
A botanical flavor with a long history in oral care, paired with peppermint to create the brand's signature taste — no synthetic flavor compounds required.
The standard
Why it made the cut
- Truthpaste demonstrates that a serious oral-care product can be sold in a glass jar without compromising performance.
- Its commitment to disclosed ingredients and minimal formulation is unusual at this price point.
FAQ
Common questions
- Why doesn't it foam?
- Foam comes from detergents like SLS, which Truthpaste deliberately omits. The cleaning action comes from the bentonite clay and gentle brushing, not the foam.
- Is it safe for sensitive teeth?
- Many users with sensitivity tolerate it well because there are no harsh foaming agents. As always, check with your dental provider for specific conditions.
Materials Library
Materials behind this recommendation
Each material below has a canonical explainer in our shared Materials Library. Open one to see how it behaves, where it belongs, and where it doesn't.
Glass
Mineral
Glass is the most inert food-contact material in most kitchens. It does not leach, does not react with food, and — in the right formulation — handles baking and freezing without concern.

Hydroxyapatite
Mineral
Hydroxyapatite is a calcium-phosphate mineral chemically identical to the mineral that makes up 97% of your enamel. In toothpaste it acts as a biomimetic remineraliser — refilling early demineralised sites with the same crystal your body already uses.
Read →
Hydrated Silica
Mineral
Hydrated silica is a mild abrasive made from silicon dioxide gel. It is the workhorse polishing agent in almost every modern toothpaste — chosen because it removes plaque without exceeding safe abrasivity thresholds for enamel.
Read →
Calcium Carbonate
Mineral
Calcium carbonate is a naturally occurring mineral abrasive — the same material as chalk and limestone. It is one of the oldest toothpaste ingredients and is still used in many natural formulations for its gentle polishing action and mild remineralising role.
