I've tried other types of alternative toothpastes before with little success. Chalky, crunchy & soapy are not exactly the adjectives I want to describing whilst brushing my pearly whites – and that had been my exact experience so far.
I opted for the mint based flavouring, to ease me in gently. The Green Tea within it is supposed to have a positive effect on teeth & gums due to the naturally occurring polyphenols.
At £2.85 / 75ml I'd say its reasonably priced in comparison to some of the big brands and using it feels no different either. One comment might be that it's doesn't foam as much as big brand products, but I'd experienced that with other 'sensitive' toothpastes & my teeth definitely feel clean, bright and polished.
