It Doesn’t Burn
Size: 4.3 Ounce (Pack of 1)
Toothpaste burns my mouth. Idk why. Started during menopause along with the many other things that changed about myself. I do like it. It doesn’t burn. But, it doesn’t give me that clean feeling.

Pricey but great for people who need something gently on the tongue or mouth
Size: 4.3 Ounce (Pack of 1)
Great alternative to traditional Toothpaste. Its a bit pricey but if you are like me you dont have to share it with anyone else because they can use regular toothpaste. The minty flavor is subtle but does not cause irritation. Easy to just just like regular toothpaste. it doesnt have any whitening in it but is a comfort for those that need a toothpaste gently on the tongue or mouth. Still does the job
