Crest 3DWhite Brilliance 深層去漬超白牙膏，2.1oz

Three weeks in and my coffee-stained front teeth are visibly lighter, even my dentist asked what I switched to. The tube is small but a pea-sized amount does the job, and the paste doesn’t taste overly minty or burn.

After just a week of morning brushing, the Deep Stain Remover formula lifted coffee stains I thought were permanent — my dentist even noticed at my last cleaning. It’s an everyday toothpaste that doesn’t feel harsh, but the whitening result is surprisingly visible.

I’ve been using this every morning for about three weeks and the difference in my coffee-stained front teeth is honestly noticeable—the everyday formula makes it easy to stick with. It doesn’t leave that weird gritty aftertaste either, which I appreciate.
