Calcium helps make strong bones and teeth. So milk drinkers had good teeth. Norway is northern Europe where they have the gene to digest milk.

Isn't the gene you're talking about related to lactose? You can still get calcium from milk, or make cheese which will naturally be lactose free.

I figured it’s that they ate all the animal. They always boiled the bones and that strengthened their teeth. I bet if you look at ancient people in tropical areas they had less teeth as well as less need for them.

Interesting, I would assume that prehistoric times required "perfect" teeth (and even overall geometry and jaw structure). You need a high quality grinding / cutting tool to rip meat easily.

FWIW, dental health outcomes for visiting dentist yearly instead of every 6 months are apparently identical. Downvoters, have a link to an article discussing some studies: https://www.bbc.com/future/article/20140926-how-often-must-w...

I haven't been to one in 25 years. I probally pushing my luck? Have all my teeth. Three cavities. My gums don't bleed when flossing. When brushing I concentrate on the gums. Use a Sonic toothbrush daily. Have a neurotic habit of using tooth picks. (I knew the dentist who developed the plastic tooth picks with floss. I couldn't stand family. Why? Because he was a rich dentist who set all his kids up for life, but coul…

If you go to a dentist now they will likely find those cavities have gone deep. I recommend that you do.

genes probably. I’m mid 30s and have never had a cavity. I go to the dentist every 6months. I also have a huge sweet tooth.

if you're mid-30s you probably had an extra enamel coating applied to your teeth at some point that may be doing some pretty awesome work protecting your molars

why would someone in their mid 30s "probably had an extra enamel coating applied"? I've never heard of that. Of course, they give you “super fluoride” when you go in for cleanings, but that's not an extra coat of enamel. I'm pretty sure there is not such technique, when your adult teeth reach their full size that's pretty much all the enamel they'll ever have, dentists can't just apply another layer or we'd all be cavity free.

The fact that we have "wisdom teeth" seems to indicate that ancient humans did, in fact, get cavities and lose teeth to them.

I have all my wisdom teeth and 3 of 4 are perfectly fine. the 4th is a little crooked but it's harmless. Plenty of people have all their wisdom teeth.

Also nobody mentions all the starchy stuff and the fruit our ancestors ate. It's just odd how people reinterpret the entire history of our species based on recent dietary fads.

Honestly our ancestors probably ate anything possible that was around. Probably a lot of half spoiled meat that you just ate if you came upon it and barely nutritious plant matter just to fill the belly. Surviving is insanely difficult, you don't know where your next meal is coming from, and you will take that rotting animal vs being hungry. I imagine cooking too didn't always happen. We take the logistics needed for…

Yeah, heat will kill all germs and break down most toxins given off by bacteria so if food isn't plentiful it would be hard to turn down a day or two old carcass just lying around. However I don't think eating half rotten RAW meat is a good idea at all. humans simple don't have the capability for that like wolves and to a much greater extend buzzards/vultures and would quite likely die from toxins given off by the bacteria.

Interesting. My Indian grandparents and g-grandparents appeared to have most or all of their teeth, and were a long lived bunch (all but one into their 90s). I can’t say conclusively all but I never noticed any gaps or problems, which is the kind of thing kids notice. The g-grandparents would all have been born in the 19th century. My Australian grandmother had all her teeth pulled out when she was 12 and wore artifi…

Why pulled?

My English grandmother was the same, though I think it was closer to her 30s. My understanding is her dental hygiene was not the best (she grew up in WW2), and it was just “easier” to remove all of the teeth and use dentures.

Oh, this is super interesting.

My grandma had all her teeth at 97 or so when she passed, and never saw a dentist, and I saw her use this tobacco toothpaste 3x per day for 25 years, until she died. https://image.slidesharecdn.com/stfactsheetcombined10-23-02-... I assume she had a combination of good genes, frequent teeth cleaning right after meals, low sugar intake, and no soda/alcohol. I have never had a cavity as of mid 30s, and I only started go…

Just curious, where did the linked image come from?

I'm imagining some sort of encyclopedia of tobacco toothpastes

Like to add to this conversation that scientists have found ways to prevent cavities but these are not made available to us. For example, genetically modified streptococcus.

Novamin is not available for sale in the US (though you can get it off ebay) and supposedly it is a toothpaste additive which can directly deposit onto teeth.

Yes it is if you order it from overseas/Canada on Amazon :)
