Travel mouth wash
Color: Refreshing Mouthwash, Size: 0.41 Fl Oz (Pack of 30)
Absolutely love these travel mouthwash packets! With Invisalign I’m constantly brushing and finishing. The little packets are so convenient to carry in my purse or work bag!

Practical for the size but doesn't last
Color: Refreshing Mouthwash, Size: 0.41 Fl Oz (Pack of 30)
Good for travellers and easy to use. It doesn't take too much space in your bag, but it doesn't last long enough

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.
