Quick questions: - What is the approximate equivalent caffeine content for, say, a 2 min morning brush? - Is it available and actually shipping, or am I "pre-ordering"? - No fluoride? Dentists say that's pretty important. Edit - to be clear, really loving the conecpt. I wish more random things had caffeine in them ;)

1) Full disclosure: I haven't run blood tests to figure out exactly how much caffeine you absorb brushing with my toothpaste. Here's what I can tell you: in 1 ml of toothpaste there is just under 80 mg of caffeine. 1 ml is a bit more toothpaste than the pea-sized amount of toothpaste that you should use, but less than the amount you see put on a brush in a toothpaste commercial. You don't swallow toothpaste and brush…

Isn't caffeine a pretty strong acid? I'm really wondering if this is any good for your teeth.

The price comparison is a bit disingenuous IMHO: coffee is $3 only if you buy a latte at Starbucks. Homemade coffee is probably less than a tenth of that even if you use capsules, and a filter coffee can be as cheap as $1.

You can also buy 20 g of caffeine in pills on amazon for around $8 compared to your 7.2 g for $15.

Why would you compare with something that is effectively the cost of sitting down for half an hour in a clean warm place with toilets and internet? (I'm assuming the cost of actual coffee at starbucks is negligible)

I use Pepsodent and it contains hydrated silica. Why is it not safe?

My guess would be that it's too hard (Mohs scale) and erodes the enamel. Hydrated silica is essentially sand

So what is the recommended toothpaste? Any ideas?

And yet takeaway coffee costs me the same price whether its at Starbucks or just a hole-in-the-wall that only do take-away.

I invented the world’s first caffeinated toothpaste - get a rush while you brush! I’m a serial entrepreneur, YCW16. Though it is a simple idea, I went through at least 60 formula iterations before I got the flavor chemistry right. This toothpaste seriously works. I actually had to lower the caffeine content from the original version. Our toothpaste gives you a quick caffeine boost that works as soon as you start brus…

"I invented the world’s first caffeinated toothpaste" We invented caffeine toothpaste years ago. https://metalab.at/wiki/Mate-dent

Can we have a packet of yours for free?

It appears that there is a patent (filed 2002, published 2003) on "blended toothpaste formulas and method for manufacture", claiming in part "A toothpaste as defined in claim 1 wherein the stimulant is caffeine". https://www.google.com/patents/US20030147817 I don't know how to read patents, so I don't know if this is a relevant patent or not.

That's an application. Hasn't been granted yet-- and it's been a while. IANAL.

Thanks. I'm guessing that "Publication type: Application" in the header is the clue I should have noticed.

Is this for real? I understand people want their caffeine hit but toothpaste seem a bit overboard. If you can't live without it, why not just buy the pills and take a pill each day. https://www.amazon.com/Natrol-Caffeine-200mg-Tablets-100-Cou... Careful, caffeine can be fatal. I'm surprised it's not regulated.

Yeah, this is bizarre to me. Kind of like adding an mp3 player to a word processor. Toothpaste has a purpose. If you want caffeine have coffee, tea, Red Bull, 5 hour energy, Monster, expresso beans, caffeine gum, or one of the million other ways to get caffeine.

Cheaper still, instant/soluble coffee is less than $0.10 / cup.

Granted, not a very enjoyable cup, but it does the trick.

It is when tooth decay is a major public health concern.

Actually no, it still isn't.

I think it is, not for you but for your children. Too many parents don't take proper care of their children's teeth and this can cause non-reversible damages. Adding flouride is not the perfect solution but it can help to some degree.
