Crest 3DWhite Whitening Tannkrem, Advanced Charcoal

My teeth felt noticeably smoother after the first week, and the charcoal really does seem to lift the everyday coffee and tea stains. The tube's easy to squeeze, even when it's almost empty, which is a small thing but I appreciate it.

Noticed a real difference in my coffee-stained front teeth after about a week, and the tube lasts a couple months since a pea-sized amount does the job. The paste has a mild charcoal taste that rinses away clean, and the 80% surface stain removal claim actually held up for me.

The charcoal formula is way less gritty than I braced myself for, and it lathers up like a normal paste. After two weeks my coffee-stained front teeth definitely look a shade brighter, so the 80% surface stain claim feels about right.
