Arm & HammerAdvance White Extreme Whitening Toothpaste - 6 Oz (Pack of 6)

Q: What is the expiration date?

Expiration date stamped in the product I purchase was over two years after purchase date.

Q: What country is this Toothpaste made??

It's made in the US by the Arm&Hammer co., famous for it's manufacture of bicarbonate of soda, or baking powder. The side-properties of bicarbonate of soda has been proven to absorb odours. This toothpaste is excellent. My family and I have been using it for many years. It leaves your mouth feeling fresh for hours!

Q: Does it remove hard plaque on tooth

I personally believe any hard plaque should be removed by a professional and then you could use this toothpaste to maintain the healthiness of your gums and teeth. After plaque removal, the gums might be sensitive to this toothpaste, it gives a bit of a burn which might be painful to those areas.
