Presumably no sugar being the primary factor. No carbs too?

When I was two years old -- apparently, I only heard it from the obvious source -- my mother went to a doctor and asked when she could start giving me candy. I'm dating myself but this was before 1990. Anyways, he said, "Never! Never give him candy. He'll develop a sweet tooth and it's game over for his teeth!".

Again paraphrasing and dramatizing, but you get the idea.

So my mom never gave me anything with sugar. To this day I don't eat any sweets and I have no cavities or tooth problems. I eat ice cream once a year, and mostly because people seem to like shaming me for not liking it. I always just have a couple of bites.

Anyways my teeth are in great shape.

> To this day I don't eat any sweets and I have no cavities or tooth problems.

Me neither. I ate candy and chocolate when I was a kid. I still do now 50 years later. Never had a problem with my teeth.

You got more than 0 cavity problems. There was an article not long ago about how sugar modifies kids mucrobiota permanently in children https://www.news-medical.net/amp/news/20210203/Childhood-die...

I have always had a sweet tooth. And while fortunately I dont have diabetes or similar. I've developed IBS and other gut ailments.

sugar doesn't cause cavities, acids do. some bacteria which is not uniformly present in people eats carbs and deposits acids. this is covered in great detail ina good book, "kiss your dentist goodbye" that i just read. ive seen improvements in my awful teeth after giving the free regimen a try
Are there any Ph tablets that are effective at neutralizing the acid that isn’t toothpaste?

I’ve only recently learned you aren’t supposed to rinse your mouth after brushing!

> I’ve only recently learned you aren’t supposed to rinse your mouth after brushing!

Wait, what? Where did you learn that?

Yeah it’s crazy, right? I couldn’t imagine walking around with toothpaste residue but it might also explain the dental work I’ve required.

Google it and you’ll see! I asked my wife about and she concurred that she doesn’t rinse but does get her toothbrush wet while brushing.

it washes off the fluoride before being absorbed! haha also learned from that book
You could just eat a spoonful of baking soda.
I put baking soda in my drinking water, as mentioned at https://news.ycombinator.com/item?id=27329115 - typically 1 teaspoon per liter
Doesn't the stomach acid instantly neutralize that?
I sure hope your stomach acid isn't finding it's way into your mouth! The point is to raise the pH in the mouth so your teeth, since acidity causes calcium to leach out of your teeth
Xylitol rinses are great too. Xylitol seems to function as a sort of “probiotic” for the mouth.
It's sort of the opposite of a probiotic. In many organisms, including many non-human mammals, it short-circuits normal metabolic processes. Xylitol-sweetened products will easily sicken, and frequently kill cats and dogs, for instance.
Yes, you’re right, it’s more of an antibiotic, but it seems to have a balancing effect on the oral microbiome.

The research is still nascent and inconclusive, though. Here’s an interesting study: https://pubmed.ncbi.nlm.nih.gov/17263856/.

> Conclusions: The results suggest that chewing gum with xylitol or sorbitol/maltitol can reduce the amount of dental plaque and acid production in saliva in schoolchildren, but only the xylitol-containing gum may also interfere with the microbial composition.

You're not supposed to eat the xylitol, just get it onto your teeth. So use xylitol toothpaste.
There are Xylitol sprays also, advertised for moisturizing a dry mouth. Spray, swish, and spit it out and little will reach your intestinal microbiome. Best done right before a time when you won't be eating or drinking so the residue has some time to act on the bacteria on the teeth (e.g., right before a shower or before bed).
Also functions as a mild laxative..
I have a friend with extreme food restrictions, they can mostly only eat animal products (plus white rice and very few other things). They also cannot brush their teeth regularly due to disability - yet their teeth look fantastic!
I remember in Sub-Saharan Africa, they all chewed on this stem (can't remember what it was), and everyone I knew had incredible teeth. Their diet was probably also fairly simple. I wasn't really a fan of the local cuisine.

When I lived in Morocco, however, it was the opposite.

Moroccan food is some of the best in the world, but they have sugar in everything. Their mint tea is something that should come with an insulin injector. They buy these giant bricks of sugar, wrapped in blue paper, and just drop them in the pot.

When many Moroccans smile, it looks like a brown picket fence.

Did I mention that Moroccan food is awesome?

The stick is likely Neem; my father did the same in Pakistan.
Yup this is me
Yeah, extreme no sugar and no carb, almost pure carnivore. Haven’t had a bit of tooth decay since.
Also, presumably, drink water. That can't hurt.
