He most likely meant refined sugars. Sugar is being added to most foods nowadays. The timeline of cheap refined sugar is the timeline of sugar addiction and tooth decay.

Why is it surprising that unattractive people try to become more attractive?

My impression of many incels is that their looks are not their problem.

It's not like their opinions are written on their foreheads. Hit on a woman on tinder she won't know. Hit on a woman in a bar she won't know. Clearly the rejection is for simply being unattractive.

Yes, and wild oats and legumes don’t exactly seem like the exception in ancient diets.

Plus another link in this thread claims ancient fruits have different sugars that don’t cause decay.

Teeth are annoying. Mine are ok, but as I get older I start to notice their deterioration.

This is the principal behind 'all-on-4' dental implants. I've no idea how good they are though. I've seen a few YouTube videos but you never really know if they're paid shills nowadays.

Seems better than dentures, but not as good as teeth. You're putting all that stress onto 8 points in your jaws and probably losing jaw bone in between.

I'd say no if you meant replacing teeth with dentures, which get levered away from your gums by your chewing and take away your palate sensitivity. I'd say yes if you meant implants. As far as I can tell from the two I have they're just the same as natural teeth, except they can't be moved around with braces.

I’m a freakishly lucky bastard, to date. Also, a freak. I have a fairly gracile jaw for a guy. A bit of a chinless wonder. I have 28 teeth. Always have, since my adult teeth came through - but I do have wisdom teeth. What I don’t have are any M1 molars. They’re just not there. Seems my maternal grandfather and my sister are the same. I’m 35, with so-so at best oral hygiene. Never had a cavity, never had a filling, ne…

Genetics play an enormous part in dental hygiene. Some people in my father in laws side never had a cavity in their entire lives - even 85 y/o grandpa (also my 28 year old wife).

Personality is often very obvious through body language.

My teeth aren't that bad but are bad. My upper teeth are nearly perfect but my bottom middle 4 teeth are a little messed up. Most people can tell because I expose my upper teeth while talking, but if I smile it's pretty obvious they're not aesthetic... For years I've been ok with this, my parents never showed me to an orthodontist. But recently I'm getting more and more self-conscious about this every day. I searched a little about this and saw that, being 22, fixing them at this age is insanely expensive (up to 10k). I wonder if someone went through this treatment and can chime in whether this 10k is worth it?

I have not gone through such a significant procedure as yours, however I did get two of my bottom front teeth replaced, which ran around 2k.

Aesthetically, and durability wise, I'd say it's definitely worth it.

If they get the proper crowns, they are far more durable than real teeth, which is superb for a "tight mouth" such as mine.

If you haven't heard of orthotropics, it sounds a bit pseuodoscience-ey, but it attempts to solve the crooked teeth issue by enlargening the jaw rather than through braces. Thus far, I have to say that I think there's some truth to exerting a little pressure to my maxilla/mandible, and if anything I can breathe much better, which for me is a bigger win than getting straighter teeth.

I think the real science here is Orthognathic Surgery [1]. I mean - I'm not an orthodontist or a surgeon, but once growth has stopped in the palate as a teenager or young adult I'd be skeptical of claims around bone growth or sculpting. Do you have any resources? [1] https://en.wikipedia.org/wiki/Orthognathic_surgery

I'm pretty sure my orthodontist did this when I had braces. He put this metal thing in my mouth that I had to crank open with a key every night for 6 months. He said it was to widen my jaw. It was absolute torture. Not sure exactly what it was or how it worked. I was like 12 when this happened.
