水晶系列牙刷

The 45° angle forces me to slow down and hit the back molars properly, which I never did with a straight brush. Five rows of bristles feel dense enough to actually scrub the gumline. My teeth feel noticeably smoother after a week of using it.

The angled head is surprisingly intuitive, I don’t even think about positioning anymore. My gums feel less irritated after brushing, and the five rows of bristles really get between my molars without effort.

That 45° angle takes some getting used to at first, but now I can't go back—it hits the gum line exactly where I used to miss. The five rows of bristles feel dense and sturdy, and my teeth have that just-cleaned squeak for hours after.
