Judging from this comment, the choice to remove fluoride seems to be a way to avoid additional FDA testing (including animal studies). https://news.ycombinator.com/item?id=12507965

Yep. & at least in this case, the FDA involvement may have good reason. Fluoride is a poison, and detrimental effects manifest themselves in much lower dosages than caffeine.

Do you realize that in addition to fluoridating water, there are studies underway to fluoridate salt, flour, fruit juices, soap, sugar, milk. Ice cream. Children's ice cream. Fluoridation is the most monstrously conceived and dangerous Communist plot we have ever had to face. A foreign substance is introduced into our precious bodily fluids without the knowledge of the individual. Certainly without any choice. That's…

Your website does not contain a list of ingredients, nor do you show photos of your box with government required disclosures on it. You admit that your toothpaste does not have fluoride, but does it contain SLS, propylene glycol, DEA, glycerin, hydrated silica, or artificial sweeteners? If so, please discontinue your product or change your formula. None of those ingredients are safe for use in toothpaste and help cau…

Point well taken! The label and full listing of ingredients will be going up there. Sorry for this omission and thank you for this comment!

Making the list of ingredients a 1st class citizen on the box could be good marketing, if the list is simple enough. I'd certainly like to see it.

The U.S. military has studied the use of caffeinated gum (which has a higher concentration of caffeine and stays in your mouth much longer) and has not seen negative health impacts. I'll upload the studies I have collected to dropbox and post a link later today! Otherwise, I've spoken to a ton of dentists about this and they weren't concerned about caffeine's impact on the gingae.

My first thought was, why this vs. caffeinated gum? I've used the gum for years (look up "military energy gum") and it's perfect. But I don't want it every time I brush. Brushing teeth and wanting a pick-me-up seem like totally orthogonal needs. Pro tip: keep a pack of caffeinated gum in your car. Great for road trips or late nights!

You don't brush your teeth shortly after waking up every morning?

I don't. I always buy the non fluorinated toothpaste from Trader Joe's. Considering it is sold out 50% of the time, it is a pretty popular option.

Not sure if you're sarcastic. If not, what does Communism have to do with anything?

I can no longer sit back and allow Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.

What flavor is your toothpaste? Outside of "Wake up with minty fresh, mentholated breath" there's no flavor specifics mentioned that I could find. So, is the flavor mint-menthol? Which kind of mint? (I personally, somewhat dislike peppermint, really dislike spearmint, but really like fennel toothpaste.) Also, what's the expected amount of caffeine per typical dispensing? How much of that are you figuring gets absorbe…

> Also, what's the expected amount of caffeine per typical dispensing? How much of that are you figuring gets absorbed during brushing?

Wondering the same thing.

He said in another comment that an average-sized 'serving' of the toothpaste contains 80mg of caffeine (roughly half the amount of a small coffee from most chains), but there's no info on how much of that is absorbed when brushing.

Brushing before breakfast seems like a weird idea to me. The mint flavor of the toothpaste would ruin the flavor of what I'd eat and I would need to brush again after. Did all of HN stop eating breakfast after this post? https://news.ycombinator.com/item?id=11753668

I believe it's generally the soapy toothpaste ingredients (sodium lauryl sulfate) that mess with your mouth chemistry and make things taste weird for a while afterwards, not mainly the mint flavour. Other kinds of toothpaste (e.g. I sometimes use an aloe vera based one) don't have this problem.

And my understanding of the before vs after breakfast teeth-brushing debate is that it doesn't that much matter which you do: do it before, and you clear off the bacteria that have accumulated overnight before handing them a load of food to work on; do it after, and your teeth are cleaner for the next few hours instead.

Only available in the US. 95% of people do not live in the US. I do not live in the US. No-one I know lives in the US.

It is significantly easier to sell many kinds of products in the US compared to other countries with large consumer bases.

That isn't always true, but could be the reason.

The US has relatively few regulations compared to places like Europe. Few enough that California can introduce new ones that become defacto national regulations.
