Smooth, mild-flavored fluoride-free toothpaste that’s easy to use daily
Flavor Name: Mint, Size: Pack of 1 (4 Ounce), Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
I’ve been using this toothpaste twice a day and it’s a good option if you’re looking for something fluoride-free that isn’t gritty and has a mild mint taste. The texture is smooth and spreads easily, and the flavor is clean without being too strong. I used it with a soft toothbrush, and it rinses clean without leaving any heavy or chalky feeling afterward. The 4 oz tube also lasts a reasonable amount of time with regular use. Pros: • Mild mint flavor that isn’t overpowering • Smooth, non-gritty texture • Easy to use consistently Con: • Didn’t feel noticeably different compared to other similar formulas I’ve tried Overall, this works well as a daily fluoride-free toothpaste for someone who prefers a gentle flavor and smooth texture.

Very good Toothpaste - I would highly recommend
Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
Please note clean mint is not the only flavor on Ollie’s website you can buy Clean cinnamon and Orange. I like both flavor although the Cinnamon has a more pleasant taste. Why I like this tooth paste because they have more are Fluoride free, more fluoride comes for industrial waste product and used as rat poison known as sodium fluoride. If you ever find a bag of concentrated flouride is has a skull and bones safety warning on it. Ollie presents as a good working tooth paste that has all natural ingredients that are safe to swallow. I know people will point out Zythol as being recorded to cause stomach issues but that’s mostly from chewing gum based products that are Sugae free in nature Since using Ollie my dentist and hygienist notice a big difference is: Gum health, teeth looking cleaner and brighter and a lot less hot / cold and pain sensitivity. Another big factor I like about Ollie is a simple thing, their tubes of tooth paste are sealed before you can use them, most store brands are not. That makes me feel more comfortable that the product isn’t tainted by someone

Works and tastes good too.
I've tried several different brands of nano hydroxyapatite toothpaste. This is the first one that makes my teeth look brighter and feel healthier. My husband likes it too.

Good Stuff!
Flavor Name: Mint, Size: Pack of 1 (4 Ounce)
I have been trying different non fluoride toothpaste and I think I have found a winner! This toothpaste leaves my teeth clean and my mouth fresh! The texture is great and I am impressed with the ingredients. The price is a little pricey but you only need a pea size amount. Very easy to use and does not run out of the tube like some non fluorides Ive used. Definitely will buy again!
