معجون أسنان حساس بالنانو هيدروكسي أباتيت والكركم الأبيض – 4.2 أونصة – عبوة من 4

Bought this for my sensitive teeth and the nano-hydroxyapatite seems to be doing its job—less zing when I drink cold water. The 4-pack is handy since I go through it fast, though the paste itself is a bit runny for my taste.

The potassium nitrate really does take the edge off the cold sensitivity, and I like that it's fluoride-free without tasting weird. Only gripe is the tubes are a bit small for the price, but the four-pack will last me a while.
