Good
Size: 4.2 Ounce (Pack of 1), Size: 4.2 Ounce (Pack of 1)
I’ve been using MySmile Fluoride Free Nano Hydroxyapatite Toothpaste for a few weeks now, and I’m really impressed! My teeth feel noticeably stronger and smoother, and I love that it’s gentle on sensitive teeth. The natural misty mint flavor is refreshing without being overpowering, and my breath stays fresh for hours. I also appreciate that it’s SLS-free and fluoride-free, so it feels safe and natural to use every day. I’ve noticed a subtle whitening effect too, which is a great bonus. Highly recommend for anyone looking to strengthen enamel and care for sensitive teeth!

Amazing
Size: 4.2 Ounce (Pack of 1)
I absolutely love this toothpaste! It feels incredibly gentle and natural, yet it still leaves my mouth feeling super clean and refreshed. Unlike other toothpastes I’ve tried, this one doesn’t have that burning or strong minty sensation that irritates my gums it’s soothing and comfortable to use every day.
I’ve also noticed a real improvement with my tooth sensitivity since I started using it, which is amazing. It gives me that healthy, clean feeling without being harsh, and the texture and flavor are just right not too strong, not too sweet.
Overall, this toothpaste feels very natural and effective. It’s definitely become one of my daily essentials, and I’ll keep buying it for sure!

Great for sensitivity + clean ingredients
Size: 4.2 Ounce (Pack of 1), Size: 4.2 Ounce (Pack of 1)
I’ve been using the MySmile Nano Hydroxyapatite Toothpaste for a while now, and it’s been a really positive switch—especially for sensitive teeth. It’s fluoride-free but still does a great job strengthening enamel and helping with sensitivity over time.
The texture is smooth, and the “Misty Mint” flavor is light and refreshing without being overpowering. I also like that it’s SLS-free and feels more natural compared to traditional toothpastes.
After consistent use, my teeth feel cleaner, less sensitive, and slightly brighter. It doesn’t foam as much as regular toothpaste, but that didn’t bother me once I got used to it.

MUST HAVE!
Size: 4.2 Ounce (Pack of 1)
I’ve never had a toothpaste like this. I noticed whitening in my teeth right away. The only thing I had to get used to is it kinda has like a gritty feeling at first, that isn’t in other toothpaste. The taste isn’t bad at all, there’s no burning in my mouth after using—- like I’ve had with other brands. I really like that it is Fluoride- free because this toothpaste gives you all the things you need without poisoning yourself. Also——- the sensitivity in my teeth is way down!!! Will continue to purchase this brand. I’ve tried Hello and I actually felt like it made my mouth worse, not MySmile toothpaste tho. Very happy!

Not too bad
Size: 4.2 Ounce (Pack of 1)
Doesn't leave my mouth feeling clean after I use. It has a weird aftertaste even if it is healthy. I prefer other brands.
