Blanx Toothpaste

when I used the first time tasted great and NOT mint, but 3-4 days later, suddenly tasted SOOOOOOOOOO mint?? any idea why? I used to wet as wet tube .. lol .. Does he still whiten my teeth, although its flavor is mint? it is always OK to use toothpaste blanx?

Sometimes more flovor is in the middle of the tube

The taste could be affected by things you eat (or not) before brushing your teeth.
the mintiness (or not) should not affect the power of money is.
