Arm & Hammer Advance White ยาสีฟัน - 0.9 ออนซ์

This tiny tube packs a serious punch—the dental-grade baking soda leaves my teeth feeling squeaky clean after just one brush. I can already see the stain defense working on my coffee habit, and it's nice to have a compact option for my desk drawer.

The travel size is perfect for my gym bag, and the stain defense is a real plus since I drink coffee all day. It's got that clean baking soda feel without being harsh, and my teeth look noticeably less yellow after a couple weeks.

The baking soda formula really does keep coffee from staining my teeth between brushings, and this little tube lasted me a full week of travel. Whitening felt gradual but noticeable by day five, which is more than I expected from a 0.9 oz. size.
