I got both the regular toothpaste and whitening pen and I really love them both. The toothpaste doesn’t foam up like a traditional toothpaste, so that might be an adjustment but I really love it and I never gag while brushing my teeth now. As for the whitening pen, I really do like it but there’s a bit of a learning curve. I read other reviews saying you should kind of scrub your teeth with it instead of just painting it on and after I started doing that I saw great results! I had some strange staining happening on the bottom of my teeth and so I used that a couple of times and it made a dramatic difference. Definitely would recommend anything from this brand because so far everything I’ve tried is 10/10 quality wise!
