I was really irritated with my teeth before because they would always bleed when I brushed them. But after I used USANA's health toothpaste I was amazed at how my teeth did not bleed anymore during brushing. This is all because of the fluoride content of the product as well as some Green tea extract which makes the product even more healthy to use. There are no artificial flavors in their toothpaste so its really all natural. There is also baking soda which helped neutralize all the plaque that I had on my teeth not to mention all the whitening properties of the product. Thank you USANA you made me want to smile again.
