This poison stained my teeth brown before I even used up the small 500ml bottle. One tooth has something bizarre going on with it like this shit is starting to errode the tooth away. I had perfect teeth before this, never had a cavity in my life. I wasn't sure if it was this mouthwash so I searched online just now and can't believe how horrible all the reviews are of this product on amazon.com. Everyone has the same problem and wants to sue procter & gamble's ass over this. Many people lost their sense of taste.
I can't believe this shit is still on the market. I can't believe it ever got past the FDA.
