I've been using this for a couple of months now and while I can't say I notice my teeth being whiter, my dentist has commented on it. The fizziness of the baking soda took a little bit to get use to at first, but you don't notice it afterwards. Teeth definitely feels cleaner and breath fresher!

Worth every penny, and I got it on sale for $1.99!! Tasted good, left a refreshing feeling, not chalky like the regular whitening type, and it does make teeth whiter.

The baking soda taste is quite overwhelming - it made me want to gag. But on top of that, it left my gums really tender and sore. I stopped using it in fear that it will cause further damage. Use at your discretion.

I can't get past the baking soda taste long enough to know whether it whitens or not. Yuck!

What a dud, nothing fantastic about this one. Will not be buying this again.

Cleans and whitens my teeth at the same time. Best toothpaste ever!

ARM & HAMMER ADVANCE WHITE TOOTHPASTE;

I trust Arm & Hammer for its baking soda ingredients and enjoy the whitening aspect of this thoothpaste.
Great taste, great results.

If you want a toothpaste that fizzes and whitens your teeth, this is for you. It gets super fizzy and leaves my mouth super clean. I really love this product. You can get a taste of the peroxide and baking soda but it's not enough to want to stop using it. Give it a try you'll love it.

Love, love, love this toothpaste!! Makes your mouth feel so clean & fresh. Like u just came from the dentist!!

This tasted like I was brushing my teeth with a paste of salty baking soda, and I didn't notice a difference in the sensitivity. I will not be using this again.
