After using it for 3 weeks my gums and inside of my lip have become really sore. It makes my teeth look great but I can't tolerate the pain.

I was extremely impressed with Crest Baking Soda & Peroxide Whitening on quite a few wavelengths. I guess because it actually does work. However; do not expect this toothpaste product to work right away, as well as, overnight. You can see a minimal effect and as time proceeds, it slowly increases, as a result. I like it because it works well for me. I've had my teeth whitened and it has helped maintain that level of whiteness. My cousin is a cosmetic dental surgeon and she uses this toothpaste. It's definitely something that is recommended by many professionals, hence why it's a good product. Overall, I was very impressed with this product and would use it again. In fact, I just used it.

This toothpaste helps tremendously for fighting off tartar and helps to keep my gums healthy. It also leaves a tastes great in my mouth!

This toothpaste with baking soda leaves a really bad feeling in my mouth.
