Why do we have crooked teeth when our ancestors didn’t? - G. Richard Scott

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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    Girl! Same!!! Except I had to wear braces for 5 years from 12-17. It was absolutely horrible! Two teeth have shifted, unfortunately in the front! I will be not doing braces again or even Invisalign or any of those because they told me you have to wear a retainer every night for the rest of your life or else they shift again! I’m just going to get the two of them shaved down and get crowns.

    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.

It will help stimulate the growth of a healthy permanent teeth. When I was a child, i used to bite the head/arm/gun/whole body off a lot of those little plastic soldier toys and in my country we eat sugar canes and a really thick and hard cookie. I really had an urge to bite those things and it felt soooo good when I did. That might explain why I have good teeth, even better than my brother, who didnt eat those things nearly as much. The funny thing is, now in my 29, i dont have that urge to bite.

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

My wisdom teeth came out when I was older and were impacted. Even today, I bite the sides of my cheek when chewing. My father and brother had the same problem. My mother's teeth were perfect. But she had to have all her teeth pulled at 24 y.o. due to weak gums. But that was way back in the early 1920s where people didn't have the dental care they have today.

    Man, I can't believe how many times I had strange contraptions in my mouth as a kid. I had weird ones that had a key that you had to turn every night to I guess expand my pallete or something. I remember they put this one torture device in my mouth it wasn't braces, but it looked like I had steel wires all over the place under and over my teeth. It was so painful I couldn't even eat. That one probably didn't stick around for longer than a month. I eventually got braces which I actually had no problem with. My two front teeth were completely overlapping along with some bottom ones. It wasn't nearly as painful as the other strange contraption I had. They even gave me a head piece that linked into some back teeth while I had the braces. I only had to wear it at night. I only had the braces in for like a year or two and I was given an invisalign sorta device that acted as a retainer. I'm 41 now, I've had all my wisdom teeth removed because of impactions. Besides the wisdom teeth I only had one extracted because it broke off at the gum line. They suggested a dental implant, and even made it sound like my face would look deformed if I didn't get it. F*ck off. I'm just going to brush and floss everyday and get fillings when needed. I only had like 4 cavities which I don't think is too bad for my age.

I had a gap on my right side from an old Army extraction that was an empty space. I had bottom and top crowding… I just smiled less. Looking at my teeth and smile in the mirror, and knowing the cost makes me sad for people who can’t afford good dental care. What a strange world we live in.
