Backed by science and clinical trials.
Flavor Name: Coconut Mint, Size: 8 Ounce
I am using this with Nano-Hydroxyapatite toothpaste and so far my teeth feel really smooth. It says it helps rebuild the mineralization on your teeth and that is why they feel this way. I'm all for that! I ordered the mint flavor and while the taste is good, it does burn. It does have a lot of oils that could cause this. I'm finding the more I use it, it is burning less. I also find if I hold it in my mouth first without swishing right away, that seems to help. If it is helping my teeth and gums, then I can work through a little discomfort. I personally think its a good product backed by science.

Great mouthwash!
Flavor Name: Coconut Mint, Size: 8 Ounce
I am very big into natural products and ingredients. This is great mouthwash that helps sensitive teeth and keeping them clean. My son uses with braces and it helps a lot since flossing is difficult.

Good flavor, acceptable results.
Flavor Name: Spearmint, Size: 1.31 Ounce
These work pretty good but don't last as long as I'd hoped for. Still a good buy though, much better than the store bought mouthwashes.

Leaves teeth feeling CLEAN!
Flavor Name: Coconut Mint, Size: 8 Ounce
I clench my teeth so my teeth break down easily. I cannot use other mouthwash as it causes canker sores and bleeding gums. This was quite minty but not over the top. After use my teeth felt soooooooo clean!! A must try with your daily oral routine.
