Ark Naturals Protection Brushle... vs Crest Pro-Health Densify Toothpa...

Crest pro-health toothpaste is in an easy to use tube with a pop up lid. This ingredient has its benefits and downfalls. It's not a harsh flavor and it keeps my breath fresh.

After just 4 days of using this product, inside my mouth was super sensitive. It's hard to describe but this toothpaste makes my teeth feel “sore”, and my mouth tingly in a bad way. I have on again off again areas in my mouth that are sensitive.
