I have extremely sensitive teeth. After two weeks on the 30-day programme, I could finally drink cold water again without flinching. So the science behind it checks out.

My dentist actually asked what I changed. I have genuinely tried every whitening toothpaste on the market. Nothing came close to what CALQIX did in 30 days.
