None of this means you brush badly, or care less than other people.
You've been maintaining a mineral — with tools designed to sell a sensation.
The foam economy.
Here's how toothpaste gets judged: in the shop, and in the first week. Does it foam? Does it taste strong? Does it feel clean? So that's what the category optimised for — a detergent for the foam (SLS), a hard mint for the "clean" signal, an abrasive for the instant smooth. All sensation.
The mineral your enamel is actually made of? Go and check your current tube's ingredients. It's not there. Foam is a detergent's party trick, not care.
Brush with the brick.
Enamel is roughly 97% one mineral: hydroxyapatite. Picture a wall of mineral bricks. Every acid hit — the coffee, the orange juice, the fizzy water you drink because it's healthier — dissolves a little of the wall's face; saliva re-lays some of it from calcium and phosphate. That tug-of-war runs every day of your life.
Strongbite's idea is almost embarrassingly literal: brush with the brick. Nano-hydroxyapatite is the same mineral, milled fine. Bicarbonate of soda cleans gently — whatever its gritty reputation, it's one of the least abrasive cleaners in any tube. Calcium keeps mineral present while you brush. Coconut oil is the base: no SLS, nothing that strips.
The questions you're already asking.
"Where's the fluoride?"
There isn't any — and we won't pretend that's a secret weapon. Fluoride works; it's why the NHS recommends it, and if your dentist says you're at high risk of decay, listen to your dentist, not a tube. Plenty of our customers run both: Strongbite in the morning, fluoride at night. This page will never tell you fluoride is poison. Anyone who does is selling you fear.
"Will it help a toothache?"
No. Pain means dentist — that's not small print, it's the actual first step. It's the step that helped me, before any paste did. Our own quiz sends people away for exactly this.
"Is 'nano' safe?"
Hydroxyapatite toothpastes have been sold in Japan since the 1980s. European safety regulators have assessed nano-hydroxyapatite for toothpaste and set exact particle specifications for the form they reviewed. And here's the ingredient list in full — four things, no "proprietary blend" hiding anything: nano-hydroxyapatite, calcium, bicarbonate of soda, coconut oil.
"Why doesn't it foam?"
Foam is what SLS does, not what cleaning is. Give the low-foam feel four days; it becomes the point.
"What does it taste like?"
Bicarb-forward: faintly salty for the first three seconds, then just… clean. We'd rather warn you than surprise you.
What the first two months actually look like.
Same shelf, different job.

No competitor named on purpose — the failure is structural, not one brand's.
Choose your jar.
All prices include VAT. Same paste in every size.
The Empty-Jar Guarantee — 60 days.
Brush with it daily. If your teeth don't feel noticeably smoother and cleaner — your tongue is the judge, not our copy — email us one line and we refund you in full. Keep whatever's left in the jar. We can afford this because most people who run the 14-day tongue test stay.
Nothing is wrong with you.
Something was wrong with the tools — a whole aisle of them, optimised for foam. You've now got the map you drew us, one jar of the mineral the wall is made of, and a tongue test that will tell you the truth in fourteen days.
That's the whole pitch.
