Scorecard
- Potency — Mixed. Hydroxyapatite remineralisation is real; no fluoride means caries protection depends on diet and brushing technique.
- Bioavailability — Strong. Topical, direct enamel contact.
- Marketing vs hype vs reality — Mixed. The "prebiotic" framing leans on weak in-vitro evidence; the rest of the formulation is honest.
- Sustainability — Strong. Recyclable aluminium tube, no SLS, no plastic microbeads, EU-based.
- Ethics — Strong. Small founder-led brand, full ingredient disclosure, no acquisition by a CPG conglomerate (yet).
Verdict: Worth it for the format, sustainability, and ethics. The "prebiotic" claim is decorative; the rest of the product is the cleanest pass on this list.
Toothpaste hasn''t meaningfully changed in fifty years. Same fluoride, same SLS foam, same artificial mint, same teal-and-white tube. The science of the oral microbiome — the 700+ bacterial species that decide whether your gums bleed or your enamel stays intact — has moved on. The toothpaste shelf hasn''t.
SuperTeeth has. The formula uses hydroxyapatite (the mineral your enamel is literally made of) instead of fluoride, and adds prebiotics designed to feed the good bacteria in your mouth rather than nuking everything indiscriminately.
Your mouth has a microbiome. The toothpaste aisle hasn''t caught up.
What hydroxyapatite actually does. It remineralizes enamel by depositing the same mineral your teeth are built from — directly filling micro-lesions before they become cavities. Clinical studies (notably the Japanese research underpinning the original Sangi formulations) show comparable or better remineralization vs fluoride, without fluoride''s endocrine-disruption question marks.
The prebiotic angle. Most toothpastes contain SLS (the foaming agent in shampoo and dish soap), which strips the oral mucosa and disrupts the microbiome. SuperTeeth skips SLS and adds prebiotic fibres that selectively feed beneficial oral bacteria. The effect is subtle: less morning breath, gums that stop bleeding when you floss, a mouth that doesn''t feel "stripped" after brushing.
Who it''s for. Anyone with sensitive teeth, receding gums, recurring cavities despite good hygiene, white-spot lesions, or anyone uncomfortable with daily fluoride exposure. Anyone with a kid in the swallowing-toothpaste phase (no fluoride toxicity risk).
Less morning breath. Gums that stop bleeding. A mouth that doesn''t feel stripped.
Who can skip it. If your dentist is happy and your enamel is fine, fluoride toothpaste from the pharmacy is doing its job and is significantly cheaper. This is an upgrade, not a rescue.
The honest caveats. It''s 4–5× the price of supermarket toothpaste. The foam is much subtler — which feels weird for about three days, then normal. And the mint is real botanical mint, not the sweetened candy-mint most people are conditioned to expect.
Verdict. The single highest-leverage swap in your bathroom. Twice a day, forever, for a microbiome you didn''t know you had.
