I got a free coupon to try this toothpaste at Shoppers Drugmart so I gave it a shot. It's fairly expensive (around 7 CAD) and the package is small (75 ml) but I found that it's worth it. I have sensitive teeth, always had and all the other whitening toothpaste on the market were pretty harsh on my teeth so I was plesently surprised by this one. After just 7 days I noticed that stains were removed quite a bit ( I'm a coffee lover - don't judge, lol). Since I'm the only one in our family with sensitive teeth even this smaller tube will last longer so the value will be worth the result.
