its called veneers
Teeth are not naturally white to begin with. They will always have a yellow hue in them unless you whiten them or have veneers that are white. The whitest natural tooth color has a bit of yellow but is mostly white.
Enamel, the outside of your teeth is transparent which allows the yellow of the dentin, the living tissue underneath, to be seen slightly. That is why natural teeth have some yellow in it. As we age the enamel thins and teeth become more yellow. Staining from any food or liquid can yellow or brown your teeth.
However you talk about white teeth of Americans. That is because many whiten. Either at home with pastes and bleaches, or at the dentist's office. I would ask your dentist about whitening if you are concerned.
Fluoride has nothing to do whit enamel color. Just strength. Fluoride helps keep enamel strong. Systemic absorption of it through our drinking water is a good thing to keep teeth healthier but not white.

Commercial white through professional whitening. Has nothing to do with brushing properly. Does your dentist use Zoom?

Should rinse with or drink water after everything you eat. Good advise.
CHX is an antibacterial and should only be used if prescribed and follow the instructions. Usually use it for a week or two then stop. It can grey your teeth.
Bacteria builds up no matter what. As long as you have moisture in your mouth, plaque will start to form. You don't really need to brush more than 2x a day, but definitely before bed. Skipping more than a 24 hour period is when bad things can start to happen.
Has plenty to do with brushing properly - whitening sessions (which are just ultrasound and water jets to clean deposits thoroughly and disintegrate tartar) are a lot faster and less painful when I started brushing properly (less deposits and tartar - if any at all -, less stuff to removal with less inflamed gums). And no, he doesn't use bleaching products nor laser treatments, only ultrasound, water jets and manual "scraping" with a final "polishing whirring tool" to remove dust and roughness, he also recommends not to use whitening products.
Also, my "commercial white" was probably a hyperbole given what American ads look like. My teeth are "natural white", not "anime blinking smile" white. Still, the difference between clean natural white and badly maintained teeth is extremely noticeable.
CHX-containing products only require a prescription if over 0,2% here, and that's only recommended for some days after a procedure. There are "maintenance" products with much lower concentrations which I don't use because I'm aware of the discoloring issue with CHX. CHX still comes in handy if someone has a condition that requires sporadic disinfection (for instance, my wisdom teeth "push" and make my gums bleed once or twice a year for a couple of days, during which 0,2% CHX has spared me infections - the first time it happened I just rinsed with salted water and ended up having to take antibiotics).
As to the underlined part, bacteria build up much slower if you take away their food and turn your mouth into an inhospitable environment, which is the rationale for striving to brush one's teeth after each meal. And other than trusting my dentist and his logic, I noticed time and again the difference between people who brush after every meal and those who only brush once or twice a day. I'm talking about people I spent/spend a lot of time with (relatives, exes) and have/had different dental hygiene habits.
You can brush properly all you want, your teeth will still turn yellow over time without using some form of whitening whitening if you are eating and drinking food stuffs that have dyes/tannins. Of course properly brushing will keep them cleaner and delay staining, but unless you drink through a straw exclusively, and only eat bleached foods, your teeth will still stain and yellow since enamel is porous.
As far as my brushing 2x a day comment, it's just to prevent plaque buildup. Which is noticeable after 24 hours. Of course everyone is different and in very rare cases, some people have almost no harmful bacteria. But brushing 2x a day is all one really needs to do. Especially if they are whitening regularly.
CHX is typically prescribed for gingivae issues. I've not seen any non prescription CHX, but yea gum irritation or slight to mild gingivitis is what we prescribe it for.
Well, I only need to do that whitening treatment once a year to maintain "cream-white" teeth (used to be twice before I started rinsing with water immediately after drinking coffee/tea/wine), and brushing after meals has become a habit, so I see no reason to change that.
CHX mouthwash comes in 0,05%to 0,09% (advertised for daily use), 0,12% (monthly treatment, whatever that means) and 0,20% (post-treatment), and gels in 0,5% and 1% here. All of those formulations are OTC and contain an anti-discoloration system for what's worth (I don't really trust it and only use CHX when told). There's even toothpaste with CHX in the 0,05%-0,09% range, just checked.
I don't trust anyone with blindingly white teeth. As with most things, we exist on a continuum. I am blessed with bulletproof enamel and you are not, but my teeth are still very much off-white. Any effort to change that, to the OP's question is uniquely american. We have whitening products and fake shit. So anyone you see with alarming android teeth is likely to be American. It isn't a feature, it's a bug.
Teeth being white/not being white is not a sign of 'hygiene'. Teeth aren't meant to stay white your whole life. That doesn't mean you're unhygienic.I have good dental hygiene
As someone having spent considerable amounts of time around yokels here in Sweden, where we also have fluoride in the water, I can 100% say that it does not whiten people's teeth.
At-home whitening, regular dentist visits with full cleaning and professional bleaching. Genetics also plays a role. My dad's side has yellowish/grey teeth, but they're strong as hell and never have cavities or such. They all also use snuff, so there's that.
My mom's side has white teeth, they're the vain side and just about every single person has professionally bleached teeth. But they also have damages, gum disease etc.
Luckily my mom and dad passed on healthier dental habits to their kids than what they brought with them as they grew up. Some of their kids still got the worse end of the dental heritage though.
White teeth are not necessarily a sign of good dental hygiene. My brother can attest to that. His teeth are rotting from the inside, but his teeth are perfectly white and even.
When you watch TV and movies everyone's teeth are white as white, check out real people and you won't find this, midlife crisis moms/dads, "influencers", actual famous people and people who have been exposed to this while growing up thinking its normal
The reason why white teeth are not always healthy is that you can brush, bleach and whatever as much as you want if you don't floss. All the food that gets stuck between the teeth starts rotting them. Flossing is as if not more important for teeth health than brushing them.
Americans have this obsession with bleach white teeth, it's not natural. The natural colour is slightly yellow. They go through a lot of processes to achieve this, such as professional whitening and having fake teeth or veneers fitted.
Im 40+. I brush 2x a day and floss constantly. (Flossing > Brushing). I keep a bag of floss sticks on my desk at work and home. I'm literally using one right now. Never had a cavity. Don't even know what a tooth ache feels like.
My teeth are not white. They have a slight yellow tint to them. But I dont take care of my teeth for the white color, I take care of them because I've seen the horrible pain other people have when they don't.
I don't think it matters what time on the day you floss, but I think it's it's important to do it soon after a meal.
I floss before I brush. It makes more sense.
Think about it, where do you usually get holes in teeth? On the front/back or in between?
Of course the answer is obvious here, as brushing teeth doesn't clean the food leftovers between the teeth which leads to it rotting and attacking your teeth. This is why flossing is important.
But I'm no dentist and probably no one here is. I know what works for me and I haven't had a toothache for many years and get compliments from my dental hygienist, even though I go to the dentist once every 2 years.
I even bough tools to clean tartar myself. I do it once per month/2 months.
But soon after Mr Xi secured a third term, Apple released a new version of the feature in China, limiting its scope. Now Chinese users of iPhones and other Apple devices are restricted to a 10-minute window when receiving files from people who are not listed as a contact. After 10 minutes, users can only receive files from contacts.
Apple did not explain why the update was first introduced in China, but over the years, the tech giant has been criticised for appeasing Beijing.
No, the fluoride is just there for the government mind control.
