Why did many ancient people have bared teeth?

Crooked teeth can be caused by many factors.

1. race/tribe
2. derivative
3. bad habits
4. dental caries/cavities
5. premature tooth loss

if it is related to the old people, it could be due to the minimal knowledge of the ancient people.

let's understand first, this abnormality is called protrusive (advance teeth)

Well, there are 2 abnormalities that make it look bulky.

teeth that are advanced (protrusive) or jaws that are advanced (prognathic)

Let's discuss it briefly, because if it's long, you can study online.

1. race/ethnicity, we in Indonesia are mongoloid race and some are negroid in the east, the jaw proportions are different, please pay attention *sorry this is not bullying or anything, this is knowledge*,
2. derivative, this contributes only a small percentage, it's just enough and needs to be considered, if from the family tree someone has an advanced jaw, there might be derivatives hehe.
3. bad habit, this thing since childhood without us realizing it, hahaha. Bad habits that cause loose teeth.

a. drinking milk through a pacifier / pacifier, sucking the thumb and lasts from the beginning the baby teeth (children2) grow until the milk teeth change into permanent teeth. So this is the logic, if an object or grass is exposed to continuous pressure, it will follow the direction of the movement, right? don't you think?

the picture is as below.

b. breathing through the mouth, this is done for example the patient has respiratory problems so that he breathes through the mouth, or it is just a habit. let's think logically, the teeth should meet up and down, so when you breathe through your mouth it opens automatically, so the back teeth don't meet up and down, so they end up going down, the top one goes down, the bottom one goes up until they meet.

so that the shape of the front teeth will open.

like this.

c. sucking lips, there are people who like to suck or bite their lower lip, usually the appearance is that the lips that are sucked are thick. Now that makes the lower teeth go backwards and the upper teeth move forward.

d. It's the same as the habit of moving the lower jaw forward (the language is naughty, nyatem) later it interferes with the growth and development of the jaw and stimulates the lower jaw to form forward than the upper jaw, the Caesar artist cake.

sticking out your tongue, this is usually because your teeth are just growing, it's itchy and you keep pushing with your tongue, eventually the teeth will grow following the direction and encouragement of the tongue.

4. Dental caries, this occurs in children whose teeth want to change from children to adult teeth, usually children's teeth are rarely cared for so that many have cavities and are porous. Now this can cause a shift from the next tooth, because the front teeth are already fragile and there is no barrier so that the back teeth move forward to fill the void, haha.

5. Loss of teeth prematurely, now TRY READING MY WRITING ABOUT TIME TO CHANGE A TEETH, So it's time for a tooth to be extracted, so don't force it to ask for it to be extracted, because milk teeth are a guide for permanent teeth to grow, permanent teeth take the place of milk teeth , imagine if a child lost its mother? What happened? Yes, where has he been, just like teeth, lost his guide, yes he just grows carelessly, this is what makes teeth messy, but too late to pick up also makes a mess hahaha. That's why check with the drg every 6 months.

etc. and much more.
