As a hygienist I love this
Flavor Name: Coconut Mint, Size: 8 Ounce
As a dental hygienist, I’m always cautious about oral care products that claim to whiten while also protecting enamel, but I’ve been pleasantly surprised by this Nano-Hydroxyapatite Oil Pulling Mouthwash. The formula feels gentle yet effective, and I appreciate that it focuses on supporting enamel health instead of relying on harsh whitening ingredients that can increase sensitivity.
The nano-hydroxyapatite is a great addition because it helps strengthen and remineralize teeth, which is especially beneficial for patients with sensitivity or early enamel wear. I also noticed my mouth felt very clean and refreshed after use, without the heavy, greasy texture that many oil pulling products tend to leave behind.
Another big plus is how well it helps with bad breath and plaque control. It leaves a smooth, fresh feeling without burning or overpowering mint flavors, making it suitable for both adults and older kids. The whitening effect is gradual and natural-looking rather than overly aggressive, which I personally prefer from a dental health standpoint.
Overall, this is a well-balanced oral care product that combines natural ingredients with science-backed enamel support. I would definitely recommend it as part of a good brushing and flossing routine.

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.
