I have been using Regenerate -products for almost one year. Dramatic difference? No. Perhaps yellow erosion signs are now slightly whiter. But may be it depends on the lighting 😉
I am fully aware of the criticism towards the product, and the fact that the Advertising Standards Authority (ASA) banned the Unilever ad in the UK.
I will make a decision regarding the continuation of the treatment after my dentist check, currently I have some toothpaste and a monthly kit left.
