Only toothpaste in my household
Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)
Love this toothpaste, no fluoride, great taste, fresh breath. Great value for the price as the tube is quite large. Only downfall if that it doesn't foam well which you will find with any toothpaste not full of nasty chemicals. Only thing my family uses.

Give it a few weeks! It works!
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I've been brushing with this toothpaste twice a day for about 3 weeks. I can see an improved whitening. My hairdresser, new one I hadn't met before, told me I have perfect teeth. Actually they're not that straight but the color of my teeth makes up for the misalignment of some of them. Flavor of toothpaste is good. Didn't cause any sensitivity for me.

Love this!
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
This toothpaste does not foam but my mouth has never felt cleaner or fresher! The taste is minty fresh and I have noticed a difference in the whiteness of my teeth since I started using it! Very effective and I highly recommend!

Baking soda never works out well
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I don't know why I decided to chance it but it didn't take long for my teeth to start aching. I realized baking soda might be the cause of my toothache issues when I switched between a few and realized the baking soda ones were accompanied by aching. I think I went with this because it claims to be for sensitivity and I thought the nhap would help whatever the baking soda affected but not the case.
If you have tooth ache, consider it might actually be the toothpaste and don't just go looking for "sensitive" labels. This might work in combination with other toothpaste. I.e. not multiple times a day but once a day and a different one for other brushing.
I've noticed not being as able to tell when it's been a while since I brushed. This was the main change so it might be effective at cleaning.
The tube is metal and hard to press but the paste consistency is less firm than others so it works out. It didn't take much to get the paste out. It gives a light foam. The taste is not sweet. It's tolerable but borders on bad.
