I love the feeling of the bubbles, like a party in my mouth, its not too strong and you can feel the foam actuaully cleaning your teeth. I love playing with my teeth with my tongue because it feels so so smooth i cant stop touching them and looking at myself every 5 minutes because as a smoker im not used to the white teeth and now i can smile all the time because colgate has got my back. Im so excited to buy more and more and maintaining this white smile. Im confident 👀
