30% Nano-Hydroxyapatite Suspension Matrix

We put back the exact mineral your enamel is made of, at a particle size small enough to settle into those openings and rebuild the surface from inside them.

Your enamel is 97% hydroxyapatite — and it's the only part of your body that can't regrow on its own.

It wears down. Acid, abrasion, grinding, age, the bacteria already living in your mouth. The causes differ from person to person. The result doesn't: microscopic openings in the surface.

Those openings are the whole problem. They're the channels that let cold reach the nerve. They're the pits where bacteria settle in and decay begins. Same openings, two consequences, depending on how long you leave them.

Most hydroxyapatite toothpastes run 5–10% — and you spit them out after two minutes. Apatex is 30%, in a serum built to stay on.

It's a thick mineral suspension, not a rinse. It holds where you place it instead of thinning out and washing away, so the particles have hours to settle in rather than seconds.

More mineral. In contact far longer. Going back into the exact places it was lost from.

Most people feel this step first — usually inside two weeks.

Theobromine

Step one rebuilds. This is the step that makes it stay.

Fresh mineral is vulnerable. Rebuild the surface and leave it soft, and you lose it again to the next cup of coffee. Most brands solve that with fluoride — it changes the chemistry of the crystal so it takes more acid to dissolve it. Theobromine solves it differently. It changes the size.

It comes from cacao. Everyone knows chocolate is bad for your teeth — the sugar is. Cacao itself has been sitting in dental research for twenty years, and this is the reason.

When enamel rebuilds in the presence of theobromine, the crystals that form are larger. Acid attacks surfaces. A large crystal has less surface exposed for its volume than a small one, so it gives way more slowly. Same weight of stone as one boulder or a bucket of sand — pour acid on both and only one survives.

Rebuild with small crystals and you've refilled a hole that will empty again. Rebuild with large ones and the repair outlasts what caused it.

It's also a food compound. Nothing here you need to worry about swallowing.

Step one rebuilds. This is the step that makes it stay.

Nano silver

Rebuilding while the damage continues is bailing a boat with the hole still in it.

Cavities aren't caused by sugar. They're caused by bacteria that turn sugar into acid.

Those bacteria live in a film on your teeth, and they produce acid every time you eat. That acid is what pulls mineral back out of your enamel — every meal, every coffee, every snack between them.

Rebuild the surface and leave them sitting there, and you're refilling a bucket with a hole in the bottom.

Silver has been used against bacteria for longer than modern medicine has existed. At nano scale, the particles disrupt the acid-producing bacteria sitting directly on the tooth surface.

It's why the mineral gets hours instead of seconds.

Less acid between applications. Fewer attacks on the mineral you just put back. That's the difference between repairing damage and repairing damage while the cause keeps running.
