Davids Hydroxi™ 敏感 + 美白奈米羥基磷灰石優質牙膏 薄荷

The baking soda and xylitol combo actually makes my mouth feel cleaner than my old toothpaste ever did. I've been using it for about three weeks and my coffee stains are fading slowly but visibly.

My teeth felt noticeably less sensitive after about two weeks, which I didn't expect from a toothpaste. The nano hydroxyapatite and baking soda combo seems to actually do something, and the peppermint isn't overpowering.

Switched to this mainly because of the nano-hydroxyapatite, and my teeth actually feel smoother after about three weeks. The peppermint is mild rather than spicy, which is exactly what I wanted for sensitive gums.
