An implantologist's own routine

“This is the exact routine I use on my own teeth — and it takes eighteen seconds a day”

Dr. Martinčević, DMD, implantologist · as told to Oral Health Today · 8 September 2026

Six three-second moments, placed at six specific times. The placement is the part that matters — and one of the six is a step most careful people get exactly backwards.

The patient who changed how I explain this

A woman in her early fifties, referred to me for two implants. Her oral hygiene was better than mine. She had brushed twice a day for thirty-five years, flossed nightly, never missed a cleaning. She apologised to me when she sat down, which is the part I still think about.

People arrive in my chair believing they failed at brushing. Almost none of them did. What nobody had ever asked her was the question I now ask everybody, and it has nothing to do with a toothbrush.

I asked her to walk me through what she ate and drank on an ordinary Tuesday.

Coffee at seven. Breakfast. A second coffee at ten. A herbal tea with lemon mid-morning, because she had given up the third coffee and thought she was doing something good. Lunch. An apple at four. Dinner. A sparkling water in the evening, sipped slowly over an hour in front of the television.

Eight separate occasions. She had done everything the profession told her to do, and nobody had ever mentioned the one variable that was actually driving her outcome.

The root cause nobody names

Brushing is mechanical. Bristles scrape plaque off a surface. That works, it matters, and I am not telling anybody to stop.

But the process that ends in a filling, and eventually in an extraction, is not mechanical. It is chemical. Enamel is a mineral, and minerals dissolve in acid.

There is a measured line where it happens. Below a pH of roughly 5.5, enamel begins giving up mineral into the saliva. Above it, the traffic reverses and mineral moves back into the surface. That exchange runs in both directions, all day, every day of your life. The only thing that has ever decided the outcome is which direction runs more often.

Each eating or drinking occasion opens roughly a forty-minute cycle: about five minutes for the pH to fall past the line, fifteen or so spent underneath it, then twenty for saliva to carry the mouth back up. Eight occasions is eight of those cycles, one after another, most of them clustered into the twelve hours you are awake and busy.

And the two brushings sit at the two moments of the day that are furthest away from every single one of them.

What a single coffee actually does

Close view of the enamel surface on healthy teeth
The surface that does the dissolving and the rebuilding. Both processes run every day; only the balance between them changes.

Take one black coffee, no sugar. Most people assume sugar is the whole story, so a coffee with nothing in it feels free. It is not, because coffee is acidic on its own, and bacteria are only one of the two routes to a low pH. The drink itself is the other.

Minute zero, the first mouthful. Within three or four minutes the pH at the tooth surface has fallen below the line. For the next quarter of an hour the surface is losing mineral. Not visibly, not painfully, and not in any way you would ever notice — a few micrometres, a quantity you could not find with a mirror.

Then saliva does its work. Flow increases, the buffering system pushes the pH back up, and the calcium and phosphate already dissolved in the saliva start returning into the surface. Around the forty-minute mark the tooth is roughly where it started.

One coffee, then, is close to neutral. That is the important part. A single occasion is not the problem. Frequency is.

Now put eight of them across a day, and add the habit almost everyone has, which is sipping. A coffee finished in ten minutes is one window that closes. The same coffee nursed at a desk for an hour is a window that never gets the chance to close, because every fresh sip resets the clock before saliva has finished the repair.

This is why two people with identical brushing habits, and identical diets measured by weight, can end up with completely different mouths. It was never what they consumed. It was how many times they started.

The one mineral that goes back in

Enamel is not made of “calcium” in the loose way the word gets used on packaging. It is built overwhelmingly from one specific crystal: hydroxyapatite. When acid strips mineral out of the surface, that is the mineral it strips.

Which makes the logic of putting it back very simple. You are not coating the tooth with something foreign, and you are not substituting a different mineral and hoping it behaves the same way. You are offering the surface the exact material it is built from, in a particle small enough to settle into the microscopic pits the acid has just opened.

The enamel surface, magnified
Magnified enamel. The material acid removes is the material the surface is made of — which is what makes replacing it straightforward in principle.

Xylitol does something different, and works on the other route to a low pH. It resembles sugar closely enough that the bacteria responsible for most decay take it up as though it were food, and then cannot metabolise it. They fill themselves with something that returns them nothing, and produce no acid from it.

Neither of these is exotic. Both have been in the dental literature for decades. What has been missing was never the chemistry. It is a format you can actually use at the moment it matters — which for most people means standing in a kitchen or sitting at a desk, nowhere near a sink.

The protocol, exactly as I run it

Eighteen seconds spread across the day, on top of the brushing you already do. Each step is placed where it is for a reason, and the reason is written underneath it. Nothing here replaces anything; it fills the gap between the two things you already do.

Step 1 — on waking

Brush as normal. Then do not rinse with water.

Two minutes, the usual way. The change is what happens afterwards: rinsing straight after brushing washes most of what you have just applied down the sink. Spit, and leave the rest where it is. This costs nothing, and it is the correction I have to repeat most often.

Step 2 — after the first coffee

Three seconds, and this is the step people skip.

Two or three sprays across teeth and tongue, held for about five seconds before swallowing. No water, no sink, no spitting. The first coffee opens the first window of the day, and it is almost always taken standing in a kitchen with a bathroom eight steps away that nobody uses.

Do not brush here. Enamel that has just been through an acid episode is temporarily softened, and abrasion at that moment removes more than it cleans. If you want to brush after breakfast, wait. This is the single most common mistake I see in genuinely careful people, and it is being made hardest by the patients who are trying hardest.

Step 3 — after every occasion after that

The same three seconds. Desk, car, canteen, anywhere.

Lunch, the afternoon coffee, the biscuit somebody brought in, the sparkling water. Each one opens a window, so each one gets covered. The format has to survive being used somewhere with no sink and no privacy, which is the entire reason it has to be safe to swallow — a rinse you have to spit out is a rinse you will not use at three in the afternoon in an open-plan office.

Step 4 — the two habits that cost nothing

Stop sipping. Finish drinks.

A coffee taken in ten minutes is one window. The same coffee nursed for an hour is a window that never closes. The same goes for a bottle of anything that is not plain water sitting on a desk all afternoon. This change is free, it takes effect the day you make it, and it is worth more than most things anybody can sell you.

Step 5 — before bed

Brush, then spray last. Nothing after it.

Salivary flow falls sharply during sleep, which means the mouth loses most of its natural defence for seven or eight hours. Whatever is sitting on the surface when you fall asleep has the longest uninterrupted contact time of the entire day, by a wide margin. If you only ever do one of these six steps, do this one.

Step 6 — what I removed

The alcohol rinse. Permanently.

Alcohol dries the mouth. Saliva is both the buffer against acid and the delivery system for mineral. A product bought to make a mouth healthier that reduces the fluid defending it is working against the very thing you bought it for — and the fresh-breath effect is gone within two hours anyway, because nothing that caused the smell in the first place was ever addressed.

Five things I stopped recommending

Reading the back of an oral care label
Almost everything in the aisle is built around the two minutes you already spend brushing, not around the fourteen hours in between.

None of these are scandals. They are ordinary products doing what they were designed to do, being asked to do something they were never designed for.

1

Whitening strips as a first step

They work on stain, which sits on the surface. If the surface underneath is porous from repeated acid exposure, the stain returns faster each time and the sensitivity gets worse with every round. Deal with the surface first; the colour usually improves on its own, because a remineralised surface scatters light differently. Patients regularly tell me their teeth look brighter without ever having whitened them.

2

Charcoal anything

Abrasive. It removes stain by removing surface. On enamel that has been softened by an acidic drink half an hour earlier, that is the worst possible combination, and I have seen the wear it causes in people who believed they were choosing the gentle, natural option.

3

Brushing harder, or more often

Three or four brushings a day does not double the protection. It doubles the abrasion, and it still leaves every one of the acid windows uncovered, because the windows do not happen at the times you brush.

4

Sugar-free fizzy drinks as the safe swap

Removing the sugar removes one of the two routes to a low pH and leaves the other one entirely intact. The drink is still acidic. A patient who switched completely to sugar-free and got worse over two years is what taught me to stop saying “sugar” and start saying “acid”.

5

Waiting for the check-up to find out

Six months is long enough for a soft spot to become a cavity that needs a drill. The window in which the surface can still rebuild itself closes quietly, without symptoms, and nothing about it hurts until it is well past the point where rebuilding was still an option.

What has actually been measured

62%fewer of the main cavity-causing bacterialaboratory · within three minutes
84%reported less stainingusers · over four weeks
73%observed less tartarusers · over four weeks
82%noticed visibly whiter teethusers · over four weeks

The first figure is a laboratory measurement. The other three are what users reported over four weeks of ordinary use, which is a weaker kind of evidence than a laboratory number and is labelled that way deliberately. It has also been dermatologically tested — a patch test on twenty adults with sensitive skin, recorded as non-irritant and non-sensitising.

What patients ask me

Does this mean I can stop brushing?

No, and if that is what you took from this, I have explained it badly. Brushing removes plaque, and nothing here does that. This covers the hours in which brushing is not physically possible.

Is it safe to swallow?

Yes — and that is a design requirement, not a bonus. A product that has to be spat out will not be used at a desk, in a car, or in a canteen, and those are exactly the places where the windows open.

Can children use it?

The formulation discussed here is the adult one. Speak to your own dentist about anybody under twelve.

How long before anything changes?

Most people who report a difference report it somewhere in the third or fourth week. Enamel does not work to a weekly schedule, and week one is not the test.

What if I already have a cavity?

Then you need an appointment, not a spray. A cavity that has broken through the surface is a repair job. This is for the surface that has not broken yet.

The limits of this protocol. It does not replace brushing and it is not a treatment. A cavity that has broken through the surface belongs to somebody with a drill. This does not remove the need for check-ups. If something hurts, has changed colour or bleeds, that is an appointment, not an article.

Where you can actually get it

Three seconds, wherever the moment happens
Three seconds, wherever the moment happens. The format is the whole point of the protocol.

It is sold on the official site and nowhere else. That is not a marketing device. A spray priced to be used six times a day does not survive a wholesale margin and a retail margin stacked on top of it, and that is the only reason the price below is possible at all.

It is not in shops or pharmacies. There is no chemist you can walk into for this, and there is no version of it sitting on a supermarket shelf.

Priced for six times a day, not for a shelf

On the three-bottle delivery it works out at €18.13 a bottle, and a bottle lasts about a month. That is the entire pricing logic: something meant to be used six times a day has to cost what a daily habit can carry, or it becomes a product people ration — and a rationed spray covers three windows out of eight.

Sixty days to test it, entirely at our risk

Every order carries a 60-day money-back guarantee, counted from the day the order arrives. Keep the bottle — sealed, opened or empty, there is nothing to send back. Email with the order number, and the purchase price and the original shipping are refunded.

Sixty days is roughly three hundred and sixty of those windows, which is long enough for the answer to be yours rather than mine.

What to do next

  1. Count your occasions tomorrow. Everything except plain water counts. Most people are surprised by the number, and the number is the diagnosis.
  2. Stop sipping. Free, immediate, and worth more than most purchases.
  3. Stop brushing straight after coffee. Also free, and the mistake I see most often in the people trying hardest.
  4. Cover the windows you cannot avoid — three seconds each, wherever you happen to be.
  5. Give it sixty days before you judge it. Week one is not the test.
