A lot of toothbrushes advertise themselves as "improved whitening" or similar things because the design of the bristles and the action (on electric brushes) actually does help them break up stains, and thus help whiten teeth, when used properly.
As for the antimicrobial claims, there are many materials that are human safe that are also naturally antimicrobial. For instance, brass self sanitizes in as little as 15 minutes, which is why it's the most common material for doorknobs.
Ok. Rub teeth against doorknob. Got it. Thanks!
Hence the origin of the term knoblicker.
yeah I get that but I sorta want to know what or why so that I can decide if im comfortable with whatever they are using. I mean its not like Im sure the fda or usda or such is filled with knowledgeable experts who are going to make sure things are safe.
The American Dental Association is probably who you’re looking for. The fda and usda don’t regulate toothbrushes in that sense so you’re not really goi g to get a legally required disclosure like you do with say tooth paste. The ADA will have a seal or mark they put on products they deem safe via testing.

They're made from fused microplastics.
Ingredients: 1 toothbrush
Cancer. At this point as an American consumer, if it's something you put in an orifice that comes from a large corporation, and is synthetic, assume it's carcinogenic
Also, if it comes from nature, assume it is carcinogenic. Cancer cells gotta eat too.

Merely existing, even if you were in a perfectly safe bubble, is carcinogenic.
Excuses were made.
Only if you’re in California
'Begging the question' means using circular logic, not that something makes one curious. An example of begging the question would be asking a heterosexual if their mother knows they're gay. Hope this helps.
While you’re actually correct, language has moved on and now the meaning of ‘prompts the question’ is the dominant usage by far.
I'm very much not worried about my toothbrushes, but if you want, looks like you can get premium toothbrushes where the stuff it's made out of is a selling point.
One example, first hit that comes up:
https://www.brushwithbamboo.com/shop/bamboo-toothbrush-adult/
- Standard soft bristles made from 100% Castor Bean Oil. USDA Certified 100% Biobased. Bristles made in the European Union.
- FSC® certified bamboo handle.
- The box encasing the toothbrush is made from paper – no tape or glue is used.
- Your bamboo toothbrushes can be used for just as long as plastic toothbrushes.
- USDA Certified Biobased. Green American Certified. Vegan. BPA-Free. Natural and Non-toxic.
That being said, I recall that re: "100% Castor Bean Oil", ricin is made from castor beans, and that's probably one of the most-lethal substances you could reasonably get ahold of and put inside yourself. :-)

https://en.wikipedia.org/wiki/Ricin
Ricin (/ˈraɪsɪn/ RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.
I remember in Moscow during the Soviet Union dsys my dad was amazed when he saw that stores were still selling horse hair tooth brushes.
I wonder if they are still being made somewhere.
Well, there are multiple parts to a toothbrush, the bristles, the handle, and anything else that may be attached to it.
The bristles, the bit that wears down, generally are nylon unless noted.
https://jingsourcing.com/p/b46-toothbrush-bristles-material/
The handle, again generally, is recycled plastic.
Added bits may be rubber.
I mean the antimicrobial must be something else.
Antimicrobial can be a lot of things, a lot of it is trademarked.
This one:
https://www.pro-sys.com/product/antibacterial-adult-toothbrush/
Says it uses "StaClean™" So what does that mean?
Well...
"Something, something, duPont"? My best guess is that it's a plastic that is non-porous so microbes can't live in it.
This one says it's infused with "Nano Silver".
https://linhart.nyc/pages/nano-silver-toothbrush
Silver does have anti-microbial properties. "Nano Silver"? Who knows.
Really you'd have to read the fine print on each brush and do the research to be vaguely certain. :)
see thats the thing. I look all over the packaging and it does not say what it is doing it. Just this bullet point of antimicrobial.
In that case it's just impermeable to microbes.
Yes, that part is called “marketing”. It’s plastic, that’s what they’re calling “antimicrobial”.
I had thought that maybe it was a non thing but alls the marketing did was make me worried that they are coating it with something like triclosan or such.

A toothbrush is actually a small sea creature who is murdered and harvested for its dental powers. /s
While manual brushing can effectively remove surface stains, electric toothbrushes are equipped with features that deliver a deeper clean, leading to a brighter smile.
They clean stains off your teeth better so they prolly dont need to add shit to the brush if their ad claims are covered by just being mechanically better. Why add any operating cost adding actual agents that prolly won't produce any noticeable difference from other mechanical brushes?
the antimicrobial suggests to me that it resists mircrobial growth on the brush over time rather than works better to remove microbes but now that I think of it maybe that is what it means although if it does then its one of those bs claims where its something that just happens by the nature of being a toothbrush. oh and manual brushes list antimicrobial,
thanks but the thing is I want to know what the specific toothbrush im going to buy is made of. What "innovations" it may be using.
There are no 'innovations'. You have electric & manual. Natural (bamboo, wood, animal bristles) or types of plastic. Some companies make metal handles with replaceable heads. It's just materials & marketing. Your teeth get whiter and cleaner because you brush them. Antibacterial just means, germs cannot survive on the materials. Like NSF restaurant tools. And usually the plastics are made of materials that will not 'shed' while using them. If... they are made correctly. Marketing is everything. 99% of it is spun into a lie. "All over body deodorant" is the latest scam. No one stinks "all over", if you do see a doctor. Basic deodorant in your pits is all anyone needs.
Are you eating your toothbrushes?
no, but I am putting them in my mouth and literally rubbing it over everything in there, and like the same one over and over again. For months.

Without context, I could understand how aliens might think toothbrushes are a sex toy.
They aren't?
Bristles can break off and get swallowed without ever being noticed. I'm sure that the average person consumes a non-zero amount of toothbrush throughout their lifetime. So yes, we're eating toothbrushes.
you have failed to make me feel better about it :)
and yes I had not even thought about that.
