This review is for the GuruNanda Gentle Giant Toothbrush.We have been searching for the best super soft toothbrush for some time now. Found the ones that have thousands of bristles in a single small head and thought they were the best. Then saw the same type but with bristles in clumps, and that was an upgrade and we thought "these are the best"... but we were so wrong.We tried these GuruNanda Gentle Giant Toothbrush on a whim, and let me tell you, it was the best whim we ever had. The good thoughts we had about the other toothbrushes were nothing compared to these. Both my DH and I can say without any doubt - even knowing that we "thought" previous brushes we tried with super soft bristles were good - that this one is the best toothbrush either of us have ever used in our entire 58+ years of using toothbrushes. I guess that the third time is the charm as this is the third super soft toothbrush that we have tried.I don't know how they do it, but these tightly spaced clumps of longer, super soft bristles clean our teeth in ways no other toothbrush ever has. They massage the gums and get into areas between your teeth that normally only floss picks would clean out. In short, it feels so good to brush with these that we actually look forward to toothbrushing and brush longer than previously. Our teeth and gums haven't looked this good in years! Highly recommended!!!
