★★★★★ 5
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.
