My daughter told me about this product line.My receding gums (years!) are nearly back up to the original gumline. I went to my granddaughter’s birthday party last Saturday and my daughter served her healthy version of rice crispy treats. I was surprised that my teeth were not hurting me, and I commented that I liked the way she had changed the recipe, must’ve been less sweet, I said. She said “no mom I guess your gums are better because the recipe is the same.”This is all a pleasant surprise because I had just accepted the receding gums and tooth sensitivity, and knew my health journey would eventually resolve these issues. Well, it just did.The toothbrush they sell is just the bomb. Stiff thin bristles that seem odd but are perfect, you will see and probably agree. My teeth and gums are so much better. I am 74. I wish I had known about these products before 1) I had my wisdom teeth removed at 18. 2) I ate a lot of fast food in college 3) I learned to get off sugar and wheat in my 40’s. One of my 8 crowns fell off, and I never replaced it and my tooth, what’s left, is fine.We are replacing every cell on our body within every seven year period. Start using stuff like this on your teeth and you will have a success story like mine!
