Cavities Heal Themselves — 7 Tricks Dentists Forgot to Tell You
Cavities Heal Themselves — 7 Tricks Dentists Forgot to Tell You━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Yeah, really. Fix themselves.
Like a cut on your arm closing up — but for teeth.
No, you’re not dumb for not knowing this. Almost nobody does.
Even most dentists don’t talk about it — partly because dentists get paid for drills, not for telling you to chill with the snacking.
So we did the homework for you.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
First — what’s actually happening in your mouth
First — what’s actually happening in your mouthPicture your teeth like tiny sandcastles.
Every time you eat, a wave of acid washes over them.
A little sand gets pulled off.
Between meals, your spit quietly scoops the sand back up and rebuilds the castle.
That’s literally what’s happening. All day. Forever.
A cavity = your castle losing sand faster than your spit can rebuild it. That’s it. That’s the whole disease.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
So the game is simple:
Pull less sand OFF (stop feeding the acid)- Put more sand BACK (help your spit out)
- Kill the germs making the acid
Every cheat code below hits one of those three.
Let’s go

The 7 Cheat Codes — Quick Look
The 7 Cheat Codes — Quick Look| # | The Hack | Saves you from |
|---|---|---|
| 1 | A Swiss gel that paints cavities away | The drill  |
| 2 | A cheap silver liquid that freezes cavities | A filling  |
| 3 | A Japanese toothpaste made of tooth-dust | Fluoride fights  |
| 4 | A sweetener that tricks mouth germs to death | Sugar damage  |
| 5 | Stop snacking like an office goblin | Hidden acid hours  |
| 6 | A “cap trick” for kid cavities (no drill!) | Crying kids  |
| 7 | Spotting the “fake cavity” that won’t heal | Wasted months  |

CHEAT CODE #1
CHEAT CODE #1The Gel That Paints Cavities Away
Imagine if your dentist could just… paint a cavity off your tooth.
Like nail polish. Except it fixes the tooth.
That exists.
Swiss scientists figured it out. Your dentist puts the clear gel on your early cavity, you sit there for 8 minutes, and it’s gone.
No drill. No needle. No “careful chewing for a day.”
You don’t even feel it.
8 minutes · 
About $150 · Zero pain
It’s been in European clinics since 2013. The biggest dental supplier in America just put it in about 1 out of every 8 US dentist offices this year.
Most people have no clue it exists.
One catch: only works on early cavities — the kind dentists call “we’ll watch it next time.” Once it’s a real hole, you’re back to the drill.

Magic sentence: “Do you do Curodont?” If yes → you might never need a drill again.

CHEAT CODE #2
CHEAT CODE #2The $3 Silver Liquid That Freezes Cavities
You know how rust eats metal until it turns black and just… stops?
There’s a silver liquid dentists have that does exactly that to cavities.
One drop on the cavity.
The spot turns black forever.
And the cavity stops growing. Forever.
$2–$5 · 60 seconds · 
9 out of 10 cavities stop dead
Wild, right? The World Health Organization put it on their “most important medicines on Earth” list in 2024.
The catch: that black stain never goes away. So it’s perfect for:
- Back teeth nobody sees anyway
- Elderly parents who can’t handle drilling
- Kids who would freak out
- Anyone who’d rather have a black spot than pay for a filling

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CHEAT CODE #3
CHEAT CODE #3Toothpaste Made From Ground-Up Tooth-Dust
Okay, hear me out. This is the one that sounds fake but isn’t.
Japan figured this out in 1978:
Your teeth are made of a certain mineral.
So they took that exact same mineral, ground it into a powder, and put it in toothpaste.
When you brush with it, the holes in your teeth literally refill with the stuff teeth are made of.
You’re putting the sand back in your castle. On purpose.
In Japan since 1978 · Works as well as fluoride in 2024 testing · 
No fluoride needed
It finally showed up in America as these brands:
- Boka (the most researched)
- RiseWell
- Davids
- Apagard (the OG Japanese one)
The catch: the American Dental Association won’t give it a stamp because their rules require fluoride. Some dentists love it, some still side-eye it.

Real talk: fluoride isn’t evil. It works. But if you’ve been using charcoal toothpaste or clay “for natural teeth,” throw it out and switch to this. This one actually has real science. The others don’t.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CHEAT CODE #4
CHEAT CODE #4The Sweetener That Tricks Germs to Death
What if your mint could actually kill the cavity germs?
There’s a sweetener called xylitol (pronounced zy-li-tol).
Tastes like sugar. Zero calories.
But here’s the prank:
The germs in your mouth grab it thinking it’s sugar.
Except they can’t digest it.
They starve. 
Your breath mints become undercover assassins.
But here’s the part everyone messes up:
One gum a day = totally useless- 2 pieces after every meal/snack = germs actually die
- Aim for 5 times a day. Treat it like brushing — a routine.
Cheapest good brand → https://www.amazon.com/Spry-Natural-Peppermint-Xylitol-Chewing/dp/B000COIT8Y
Super toxic to dogs. Never leave it around pets.
Don’t go wild — normal amounts (like 2 gums, 5 times/day) are totally fine. Just don’t eat a whole bag.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CHEAT CODE #5
CHEAT CODE #5Snacking All Day Is Worse Than a Whole Cake
This is free. Nobody makes money off it. So nobody will tell you.
Remember the sandcastle?
Every time you eat anything sweet, starchy, or sour — a wave of acid washes over your teeth for about 30 minutes.
That’s 30 minutes of castle dissolving.
Then your spit spends the next hour rebuilding.
Now look at this:
| How you eat | How long acid is attacking |
|---|---|
| 3 meals · water in between | ~90 minutes/day |
| 3 meals + 2 snacks | ~2.5 hours |
| Sipping coffee + grazing nuts all day | 6–8 hours |
Same exact calories. Way different damage.
Your “healthy” coworker who sips their latte for 3 hours and eats almonds at their desk? Their teeth are dissolving right now.
The fix is free:
- Eat fast, finish it
- Water after (not more food)
- Close the kitchen between meals
That’s it. No product. Best hack on this list.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CHEAT CODE #6
CHEAT CODE #6Kid Cavity? Skip the Drill Entirely.
Picture putting a case on a cracked iPhone instead of taking the whole thing apart to fix it.
That’s this trick.
Kid has a cavity on their baby tooth? Instead of drilling, the dentist slides a tiny metal hat over the whole tooth.
No drill. No numbing. No tears.
The germs under the hat run out of food.
They starve and die. Problem solved.
In 2024, scientists checked every big study on this. Result: it works ~50% better than regular fillings.
Zero trauma. Zero “I hate the dentist forever” memory.
The catch: only for baby teeth, and you have to find a dentist who does it. It’s normal in the UK. US dentists? You’ll have to call around.
The proof → https://pmc.ncbi.nlm.nih.gov/articles/PMC7148518/
Magic sentence: “Do you do Hall crowns?” If yes → your kid never gets drilled.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CHEAT CODE #7
CHEAT CODE #7The “Cavity” That Isn’t Actually a Cavity
This one could save a parent months of crying into toothpaste.
Here’s a thing nobody tells you:
About 1 in every 8 kids has teeth that LOOK like cavities but aren’t.
The tooth just didn’t form right when the kid was a baby. It’s built different. Chalky. Soft. Shows up as white, yellow, or brown spots on their new adult molars around age 6.
No amount of special toothpaste, natural remedies, or healing tricks will fix these. They’re not cavities. They’re birth defects of the tooth.
How to tell them apart:
| What it looks like | What it actually is |
|---|---|
| One small matte white dot | Early cavity → you can heal it |
| Yellowish/brownish patches on more than one tooth | Chalky tooth → needs a dentist |
| Teeth that hurt even when everything’s clean | Chalky tooth → sensitive for life without help |

Miss it till age 14 → expensive crown territory + years of pain.

If you’re an adult with normal teeth:
- Brush twice a day with hydroxyapatite toothpaste OR fluoride toothpaste
- Spit, don’t rinse (keeps the good stuff on your teeth)
- Eat meals in windows. Water between.
- Floss OR waterpik. Pick one. Actually use it.
If you’ve had a cavity recently:
- Ask your dentist for prescription-strength fluoride toothpaste (night use)
- Xylitol gum — 2 pieces, 4 times a day
- Any “we’ll watch it” spot → ask about Curodont or silver liquid (SDF) BEFORE accepting a drill
If you have a kid under 8:
- Check their new adult molars around age 6
- Any chalky/yellow patches → go straight to a pediatric dentist
- Baby tooth cavity? Ask about Hall crowns before they drill

Your turn, 1Hackers
Your turn, 1HackersHonest question: out of these 7, how many did YOUR dentist ever tell you about?
Most of us are sitting at zero. Drop your number
= 0 of 7 — my dentist told me nothing
= 1 or 2 — partial credit
= 3 or more — your dentist is a unicorn, drop their name so we can all switch lol
