We tried Shine because my youngest son has several cavities and all of us have rather yellow teeth.
After just a month, all of our teeth were noticeably whiter (sorry, I didn’t think to take before and after pictures).
But, more importantly, my youngest son stopped complaining of any and all pain in his teeth. We have not visited the dentist yet. But, when we do, I am sure that we will get good news. 🙂
