What is that?

Left me asking "what was that" I had the worst taste in my mouth after using this, even my wife said I had an "off taste" tried it several times after and same results

I have heard this stuff can turn your teeth a brownish color - I personally have not experienced that, but my partner has noticed a bit of discoloration.

I like that the taste is not to strong and it feel that it does a pretty good job at prepping my mouth and teeth for a brush.
