I was born without "Wisdom teeth", which my Dentist claims is widely accepted as human evolution. (apparently the number of people born without them is growing)

But I also have a bad, and getting worse "popping jaw" issue. where my jaw pops (loud enough to make my ear ring for a while after) or locks up when under too much pressure or opened too wide.

Her advice is to eat soft food.... which seems to go against what TFA suggests we should be doing.

I don't see what the selective pressure for this would be, since people with wisdom teeth just have surgery to remove them, so there's no real difference in terms of reproductive fitness right?

I think this is mainly a US and Australian thing: https://www.sciencealert.com/no-you-probably-don-t-need-to-g...

In Australia it's particularly bad. During a checkup my dentist casually mentioned how he'd be removing mine (at a later date), even though he could provide no reason for doing so. The cheeky bugger just assumed I wouldn't ask why!

Since then my trust in dentists has been further eroded by this Cochrane review https://www.cochrane.org/CD004625/ORAL_routine-scale-and-pol... that concludes with:

Authors' conclusions: For adults without severe periodontitis who regularly access routine dental care, routine scale and polish treatment makes little or no difference to gingivitis, probing depths and oral health-related quality of life over two to three years follow-up when compared with no scheduled scale and polish treatments (high-certainty evidence). There may also be little or no difference in plaque levels over two years (low-certainty evidence). Routine scaling and polishing reduces calculus levels compared with no routine scaling and polishing, with six-monthly treatments reducing calculus more than 12-monthly treatments over two to three years follow-up (high-certainty evidence), although the clinical importance of these small reductions is uncertain. Available evidence on the costs of the treatments is uncertain. The studies did not assess adverse effects (of the scale and polish treatment).

I know it's a bit of a joke that HN commentators assume they know more than the experts, so just to be clear: I consider the experts here to be the study authors.

It's more likely just race mixing, since if I remember correctly, native americans don't grow them.

I don’t know about you, but caffeine makes my jaw very tense and the popping bad.

If I manage to get through the three day come-down of caffeine cessation the popping goes away and my jaw starts to relax.


huh. I'm not sure I'm ready to do that... :-(

Howdy! Just saw your reply.

I got through the caffeine withdrawals last week. I haven’t had any caffeine since Monday last week.

Those first few days are unpleasant.
