Shumitect 溫和美白 EX 牙膏 (1450ppm) 藥用 (90g)

After just a week, my teeth feel noticeably less sensitive to cold water, and the 1450ppm fluoride is a nice bonus for cavity protection. It lathers up well without being too harsh, and the taste is mild enough for daily use.

The potassium nitrate really works—my teeth don't ache at all after brushing now, even with the 1450ppm fluoride. It's a relief to whiten without the usual sensitivity.

My gums have been way less sensitive since switching to this, and I love that it still has 1450ppm fluoride for cavity protection. It lathers nicely without being too harsh, and the mint flavor is pleasant but not overpowering.
