DIRECT MINERAL DELIVERY
The mineral was never the problem. Getting it to stay was.
Here is the whole mechanism in one sentence: toothpaste rinses away before the mineral can soak in, and this chew dissolves slowly so it actually reaches your enamel. The rest of this page is why that matters.
STEP ONE OF THE EXPLANATION
Your enamel is made of a mineral.
Roughly ninety-seven percent of the outer layer of your tooth is a mineral called hydroxyapatite. Not a coating on the tooth — the tooth itself.
That mineral breaks down over time. Age does it. So do some medications, dry mouth, acidic food and drink, and the hormonal changes around menopause. As it breaks down, the enamel gets thinner and more porous, which is why teeth start reacting to cold, looking more yellow (you are seeing the darker dentine underneath), and feeling fragile at the gumline where enamel is thinnest to begin with.
So the problem is a material problem. You have less of a specific mineral than you used to.
STEP TWO OF THE EXPLANATION
Toothpaste is a cleaning product, not a delivery system.
This is the part that usually lands. Most people assume that if a product they've used for years didn't work, they did something wrong — brushed too little, waited too long, chose the wrong brand.
What actually happened is a format mismatch. Brushing is designed to disrupt plaque and then be rinsed away, and it does that well. But it means whatever mineral was in the paste gets roughly two minutes of contact before it goes down the sink.
Two minutes is not enough time for a mineral to work its way into the microscopic pores in enamel. It is the hose-on-the-garden problem: the water lands, but it never soaks in.
None of that is a knock on toothpaste. It is doing the job it was built for. It just isn't the job of putting mineral back.
What actually happens when you take it
What to expect, honestly
Weeks 1–2 · Mostly nothing

Be prepared for this. You are building a habit, not seeing a result. The only thing that should change in the first fortnight is that taking it stops feeling like a chore. If you are expecting a difference here, you will quit before the product has had a chance.
Weeks 3–6 · The cold-water test
Weeks 3–6 · The cold-water test
This is where most people notice something first, and it is usually temperature. Cold water, ice cream, cold air on a walk. Not the sensation disappearing — more that it stops making you flinch, or it fades faster than it used to.
Weeks 6–12 · Steadier

Sensitivity tends to become less unpredictable rather than simply less intense. Some people also notice their teeth looking slightly brighter, which is not whitening — remineralised enamel is less porous and less translucent, so less of the darker layer underneath shows through.

Enamel loss is ongoing, so this is not a course you finish. It works the way a daily vitamin works: it is doing something as long as you keep taking it. Most people move onto a subscription at this point simply because they stop wanting to think about reordering.
What this won't do
It will not regrow gum tissue. Recession is a separate problem from enamel loss, and no chewable is going to reverse it — if that is your main concern, see a periodontist.
It will not fix a cavity. Once decay has broken through the enamel, that is a filling, and no amount of mineral changes it.
It will not whiten your teeth in the way a peroxide product does. Any brightening comes from enamel becoming less porous, which is subtle and slow.
It will not work in a week. If anyone in this category tells you otherwise, that is the moment to be suspicious.
And it is not a replacement for seeing a dentist. If you have pain, ongoing treatment, or a specific diagnosis, talk to yours before adding anything new. We would genuinely rather you asked them than took our word for it.
Ninety days, then decide.
Long enough for the mechanism to have done something, and short enough that you're not committing to anything you can't walk away from.
