Crest 3DWhite 美白牙膏，進階北極冰涼清新

The Arctic Fresh taste is so clean it actually makes me look forward to brushing now, and I've definitely noticed my coffee stains fading after a couple of weeks. It does what it says about tackling surface stains without any harsh grit feeling.

I’ve been using this tube for two weeks and my coffee-stained teeth are noticeably whiter — it really does lift surface stains like it promises. The paste has a clean, cool taste without being too strong.

The arctic fresh flavor is surprisingly crisp and not at all overpowering, which makes morning brushing much more pleasant. I've definitely noticed a difference in surface stain removal after just a few days of use.
