Explore the prevailing scientific theory of why crooked teeth and impacted wisdom teeth are recent developments in human evolution.
--
According to the fossil record, ancient humans usually had straight teeth, complete with wisdom teeth. In fact, the dental dilemmas that fuel the demand for braces and wisdom teeth extractions today appear to be recent developments. So, what happened? While it’s nearly impossible to know for sure, scientists have a hypothesis. G. Richard Scott shares the prevailing theory on crooked teeth.

"Heavily relied of perfect vision," and that's exactly it. My optometrist did a study on this, and the greatest jumps in the number of people with glases are after wars. He theorizes that the reason people need glasses today, is because all the people with perfect vision *were* the hunters, and the warriors, so they died more often, leaving people with better vision behind to have a better chance at survival. This is also why we don't see as many animals with vision problems, because there is no process for protecting them or selectively sending out to be the ones hunting and fighting.

My father had perfectly straight teeth and his wisdom teeth. My mother had normal sized teeth but a much smaller jaw so she ended up with very crooked teeth and wisdom tooth extractions. I ended up with crooked teeth and braces , but all my teeth came in, including my wisdom teeth, because I had an old-school dentist who didn’t believe in pulling teeth unless it was necessary. But it is true, once you get into your middle age, your teeth to start to shift back. That’s why so many adults now are wearing Invisalign in their 50s. On the flipside, for a lot of us it’s just too much of a pain to go back to the whole braces thing.

This video makes so much sense. I had a eureka moment after watching it. I think that eating CARROTS🥕during childhood could be effective at creating straight teeth. My parents both had crooked teeth and bad bites during adolescents and required braces to get straight teeth. Meanwhile me and 4/5 of my siblings developed naturally straight teeth. One sibling developed crooked teeth with a severe overbite and he had to have braces. We all ate the same diet except the sibling that developed bad teeth. One food that he never ate was raw carrots which the rest of us had as a daily snack.

@iLPDark Год назад

Dr. Weston Price was a dentist who studied the jaws and diets of indigenous populations around the world. He found that Indigenous people that grew up eating their natural diet had almost always perfect dental arches, jaw width, straight teeth and no tooth decay. He found that changes in the diet were able to drastically descrease this kind of dental health within even 1 generation ( the kids of these people). This means the kids started eating a western diet (flour, sugar, canned, processed, etc) and developed the same problems, we nowadays have. NOW: while there may be a relation between chewing hard foods and dental health, he found the key in havin perfect development to be nutrient density, which is present in the indigenous diet and absent in the western diet.

@tyaajathailani Год назад

@spacecraftthing3518 Год назад

Thank you

@alwaysmycamera Год назад

Actually, even if you ear raw food now, your jaw size has already been predetermined genetically years ago from your ancestors, however you could maximise your growth by chewing harder food tho, it will not magically grow your jaw. You could still end up with dental crowding even with chewing harder food, since you’re born with a smaller sized jaw gene.

Using "shrank" in past tense is wrong here though. This is not a change that happened some time in the past. This is an environmental change, not a genetic one, as they said in the video (recall the monkey experiment).

@user-jc5xs1fr4l Год назад

I chewed soft foods as a kid (eggs, pasta, rice, bread, some meat) and I never needed braces, my teeth are 99% straight with a slight imperfection to the lower front. The only explanation I can give you is that I never liked sugar that much so I never really had it often. No sodas, no sweets. So perhaps that is the culprit, excess sugar. I can't think of any other variable. My diet was never anything spectacular except for the fact I don't do sugar. I also have had no issues with any wisdom teeth.

This is indeed a well known idea! I also experienced it first hand because I hated chewing and only ate soft baby food, requiring braces a bit. My sister who was more favorable to chewable foods has straight teeth. Also, it seems like the States has more problem with braces due to how their baby foods are processed and presented (like apple sauce). In Korea, not as many kids need braces because they are trained to chew some stuff, even like rice porridge, as a baby.

It should also be added that mouth breathing since adolescence can influence dental formation. Teeth alignment is influenced by how usual the jaw is closed.

@bbbbbb3734 Год назад

Precisely. When your mouth is closed your tongue tends to rest on the roof of your mouth and thus apply force that affects how your maxilla develops. Mandible follows after maxilla. I suffer from a lot of allergies and spend majority of the year nose very congested. Most likely due to this my jaws ended up underdeveloped. My brother was even worse and also had nasal polyps. Very recessed too.

Our jaws have evolved to be smaller/weaker given the changes in our diet. I remember a program on TV comparing medieval jaws with modern ones, and even in that relatively short time period noticeable changes have occurred. Slightly related - in the UK urban foxes have become less intelligent and weaker jawed than their cousins that remained in the country areas since scrounging food remains left over by humans doesn't require the biological cost of a smart brain etc. That's been recorded over the last 50 years or so.

All four of my wisdom teeth came in, the top two came in fine, the bottom two where impacted. One came in FULLY SIDEWAYS, never emerged from the gum, and pressed against the molar next to it in such a way it developed a huge cavity. I had to get all five of those teeth removed, and it caused me massive jaw pain because I already have an overbite.

I was on submarines in the US Navy. Before we could go to sea the first time, we all had to have their wisdom teeth removed. This was to prevent having to pull off of patrol to evacuate sailors with infected wisdom teeth. It’s so much of a problem that they preemptively remove everyone’s wisdom teeth.

I've read that the dietary change from paleolithic to agriculture ten thousand years ago coincided with changes in human bone structure. People on average became shorter and bone density decreased brought on by a lack of nutrition in plant foods/grains compared to animal nutrients. Weston A.

People with abnormal way of swallowing often have a V-shape upper jaw, whereas people with normal swallowing have a U-shape jaw.

My comment was regarding saying it was due to 'microfractures'. Also Iook up functional appliance therapy outcomes (such as twin blocks) on true mandibular growth rather than protrusion. Lots of relapse later in life for kids that had functional appliances under the assumption there's true modulation of growth. Also yes palatal expansion happens with a tongue, but that's because there's a suture there. No suture for the mandible. Lots of malocclusion caused by retrognathia. Does a different diet influence mandibular growth? Maybe. But it's not due to microfractures

I was the same way, I had a small v shaped jaw in spite of my adventurous eating habits and love of chewing on chicken bones. Because of my small jaw and airway, I started grinding my teeth at night very young, and my jaw never got any wider from that, even though my molars were worn down. I don’t think these theories add up. Why can an infant get proper jaw formation just from keeping good tongue posture while nursing… but children and adults need violent, strenuous chewing? What happened to the tongue posture theory? I thought the tongue was this mighty force that could change the shape of your whole face, no chewing required. I’ve read that dental malocclusion actually begins in the womb, probably because of nutrient deficiencies. (Not a lot of chewing going on in utero.) And that makes more sense to me.
