Toothpaste

What kinda toothpaste is everyone using these days?? I think I need a different kind. I’m noticing my daughters top 4 teeth are getting less white, almost yellow tint. And looks like she has some tartar on bottom 2. However I’ve literally been brushing her teeth since before she’s even had teeth!! And I brush them 2x a day. So I’m guessing now maybe it’s the toothpaste I’m using. Because it’s not from lacking of brushing. Right now this is what I’m using.

Looking for any other suggestions?!!? Thanks!
