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.

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 have a permanent retainer that builds up a little placque even with regular flossing so it’s nice to get that cleaned.

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

I don't think an extra molar at age 16 is going to let you survive after all your other teeth have fallen out. I would guess the wisdom teeth are either waiting for your jaw to mature or are in the process of devolving to never erupt at all.

1 drop clove oil, 1/2 cup water. Swish regularly. It's an antiseptic. 19 years ago I went to the dentist and he told me I needed to have a cavity filled. I skipped that. I didn't go back (or to any other dentist) until last year. Got the x-rays. No cavities. Stuff works. Oh and stop eating sugar.

Either the first dentist thought you had a cavity when you had none, or the second one missed it.

One of them was just wrong.

Although this wouldn't apply to ancient humans, I have heard the hypothesis that many people in olden times didn't have as many problems with cavities because many people drank well water. And well water has naturally occurring fluoride.

There's strong evidence. Fluoridation as public health policy modernly was partly driven by evidence from Colorado Springs, where naturally higher than typical fluoride levels caused better than average dental outcomes.

To respond to a sibling comment: the relative levels have been looked at, in detail, and existing policy reflects what we've learned from that. Scaremongering over it influences real negative health outcomes, particularly amongst those with the most limited access to comprehensive dental care. Flouridation ain't quite as big as say sanitation, or antibiotics, but it's still up there on the list of biggest public health wins ever. By all means investigate it critically, but perhaps in a way more sophisticated than "have they looked at it in more depth than me spending 10 seconds googling?" imo.

Antiseptic regrows enamel?

No. Saliva regrows enamel.

"The Verdict: You can do a lot to protect and strengthen your tooth enamel, but once it has eroded, it’s gone, baby, gone!" Says webmd.

The question should be "where are the missing teeth?, and why?

Wouldn't they be scattered? Pluck rotten tooth, toss...years later die and leave a big collection of bones, while the little tooth just erodes away?

Badly damaged teeth also tend to splinter and crack, leaving little from the original shape to recognize.

The question is, where are the half-decayed teeth that must statistically be present in skulls, because people die of unpredictable circumstances?

Or he had a boat payment due.

Seriously though... some dentists will fill any tiny crevice, others wait until there's more clearly a cavity. I'm not sure why the difference.

Cadbury, since 1824. Although it may have just been acquired or rebranded at that time.

Pretty sure my caveman ancestors cobbled together the first Jolly Ranchers, otherwise why would I think they're so delicious?

Just thinking about Jolly Ranchers makes me want to floss my teeth.
