Colgate Fresh Confidence, its hard to find as not all shops stock it, but this one I find makes my breath fresh for ages. -rolleyes
Since last summer I'm a Colgate Green Tea user. Love it so much I even asked my dad to bring some with him when he's back.
I stopped using Colgate a while back since it felt TOO clean... I use Sensodyne and Rembrandt and the occassional Arm and Hammer one with baking soda
