I've been using the Boku sensitive toothpaste twice a day for almost 2 months now and it's definitely improved my tooth sensitivity since I first started. I used to have to be extra careful about what I ate or drank, specially while out in the cold because the pain I felt was unbearable. Now it's like a magical coating is protecting them because it's barely noticable anymore. I also really like that it doesn't taste bad, and it leaves my teeth looking a few shades lighter and my breath stays pretty fresh for a decent amount of time after using. The only thing I would change is the consistency because it's a lil thin and kinda flings everywhere on my spin brush but that isn't enough to make me dislike it.

Works amazing! Worth the price!

Size: 4 Ounce (Pack of 1)

I absolutely love this toothpaste, I read an article where you can 100% use it with your Sensodyne or Colgate sensitivity toothpaste to get the sensitivity benefit from that as well as the remineralizing from this toothpaste. I didn’t notice a texture difference at all, the taste was good, I will definitely be buying this again. I used it with David’s coconut oil pulling and my teeth feel amazing, no sensitivity to cold or hot anymore! Buy it yesterday you won’t be disappointed

Not super strong

Size: 4 Ounce (Pack of 1)

This is the stuff I reach for. It’s mild enough where I don’t feel like people around me can smell inside my mouth. But still powerful enough where my mouth feels fresh. Good for my sensitive teeth too. Very helpful
