Euthymol Natural Flouride-Free Formula/Strong Mint

Would give zero stars if I could. I wasn’t expecting much more than what it claims, but I did notice a few oddities. For reference, I’ve been a dedicated sensodyne user for years. I tried this on recommendation from a friend, who, I trust had the best intentions, but after reading more into it, this is the formula made for the US and not comparable to the one made for the UK. From first use I did not feel that “clean” feeling I enjoy after flossing and brushing with an electric tooth brush. That was a let down and where I should have cut this short. I tried turning up the strength and double brushing, but it was pretty much useless. I let it slide based on the assumption that this feeling I was missing may have been attributed to sensodyne’s formula. The taste is great. That’s all that’s redeemable in my opinion. I regularly get cleanings and ocasionally will do some at home whitening in between. My diet has not changed, but my teeth are much, much more yellow than when I started using this, and have some pretty bad stains now. I’d never had staining like this, even when I was a heavy coffee drinker (which I don’t drink now). Even though I started brushing more (after every meal now rather than morning at night), I saw no real improvements, only deterioration and disappointment.
