Bests & Worsts Reviews from Amazon

I’m a dental hygienist and have been recommending and using these for Years. I have also been using them for my 2 boys who have never had a cavity even my son with autism and the softness prevents any pain when brushing and prevents gum recession. They fit all oral-b brushes except the new Olio. I apologize for giving this 1 star. It deserves 5 but I know we all look here first before buying. I just made this exception because I have more experience with this product than anyone here.
