Works!
This is an updated review changed from 4 stars to 5 stars after using it for a week. This toothpaste actually removed Matcha Green Tea stains that were between my teeth and other tight areas my hygienist couldn't get into. I'd say this is a product for stubborn stains and I wouldn't use it more than maybe a week at a time because it's expensive for the small size you get and I'm not entirely sure what the long term effect is on the teeth.

A month’s worth of toothpaste!!
Does it work well? Who knows. The tube is maybe 4”, so tiny I needed a magnifying glass to read the contents. Maybe month’s worth of toothpaste!!!

Next day results guaranteed!
I got this product to get rid of stubborn coffee stains and right after the first use, I saw immediate results. Shockingly good toothpaste with visible results.

It Really Works
In desperation, I bought this toothpaste. In April of 2024, I noticed some green on my front teeth - not the spinach type that can be removed. A call to my dentist’s office to schedule a cleaning became 5 visits that were inconvenient for my schedule and about $700 in costs for a “deep cleaning” that only dulled the appearance, but did not actually whiten or brighten my smile. My dental health, otherwise, is extremely good!
When I noticed the green creeping back, I just couldn’t stand the idea of starting with the time element or cost of the dentist again to get such lackluster results.
I don’t recall if I saw a commercial for this product, or if the listening ears of big brother caused Amazon to suggest this product, but I bought it. And when it arrived, I was taken aback because it seemed like a very small tube for the cost. But my opinion changed after the first use. And then after a week. First, this paste sticks better to my toothbrush as I’m applying it than my regular Crest toothpaste does. But it has brightened my smile, and definitely making the green disappear. I’ve been using it for nearly a month, and when I saw it on Amazon Prime Day for 50% off, I ordered a second tube! I do not notice my teeth to be any more sensitive, and the taste is clean and minty. I’m aiming to finish the first tube and then return to my regular toothpaste, using this one for touch ups as needed. Pardon the up close photo. I should have taken a “before” shot!
