I wanted to write a review. I bought a Fresh Boost a couple of years ago by accident. My teeth have always been sensitive and eating apples or grapes meant brushing teeth would be really painful. A week after I started on SprinjeneI noticed my sensitivity was gone. I could eat fruit and then brush my teeth with no pain. On top of that, I had to change dentist a year ago. When he looked at my gums he said mine were one of the healthiest gums he had seen in a long time. I only attribute it to Sprinjene because my gums used to bleed during dental cleanings. Great product. Please, don't change anything. It's perfect as is.
