It doesn't foam because it doesn't contain any foaming agents. The strong mint flavor definitely had a minty taste. It's a strong mint, but I didn't notice the harshness that's often associated with toothpaste (though this may vary from person to person). It's supposed to restore the natural whiteness of your teeth. While it might not be a good choice for those looking for bright white teeth, brushing with it daily should effectively remove stains from food and drink. While it doesn't contain fluoride, it does contain hydroxyapatite, which may help prevent cavities. Ingredients: Cleaning Agent: Calcium Carbonate, Hydroxyapatite, Coral Powder, Hydrous Silica, Charcoal; Cleaning Aid: Sodium Bicarbonate, Pentasodium Triphosphate; Binder: Xanthan Gum; Sweetener: Stevia Leaf/Stem Extract, Xylitol; Humectant: Dipotassium Glycyrrhizate; Flavoring: Peppermint Oil, Illicium Verum Fruit/Seed Oil. There's a warning not to swallow.
I felt refreshed after brushing my teeth. I felt like I didn't have to worry about bad breath in the morning.
I wanted to naturally whiten my teeth, and I bought this product because it had decent reviews on other websites. I didn't expect much after just a few uses, but it definitely exceeded my expectations and made my teeth whiter overall. (It wasn't artificial white, but it did seem to lighten the yellowing.) I plan to continue using it. *The instructions say to apply this product without wetting your toothbrush, but since it's a powder, it does fly off. I also think it might have been a good idea to use a toothbrush from the same brand as the set.
I feel like my teeth are smooth and clean. I like how it leaves my teeth feeling refreshed after brushing. However, since it's a powder, if you start brushing with your mouth open, the powder will come out of your mouth and cause a mess. Just be careful.
I won both the toothbrush and this one. I'm particularly careful about my oral care and have used a variety of toothpastes, but this was my first time using powder toothpaste. Unlike paste toothpastes, it doesn't foam up as much, so I think it will help me develop the habit of brushing thoroughly. I normally use whitening toothpaste from overseas, so to be honest, I didn't notice much of an effect from this product, but I think it would be good for people looking for a gentle whitening toothpaste that isn't too harsh. It's easy to carry when traveling, and best of all, it's not a liquid, so I thought it would be convenient to take with me when traveling abroad. Thank you for this wonderful opportunity (^^)
