Thank goodness

i really needed this tooth brush. It feels great and performs miracles on teeth. My son used it for the first time and his teeth literally changed before my eyes. We use charcoal toothpaste but I allowed him to test this toothbrush with regular toothpaste. The results were shocking. It was as if he went to the dentist and had a teeth cleaning. I’m blown away by this. The only negative is that the cast does not fit the toothbrush heads and the heads are a bit small. I think a medium sized brush would make this toothbrush a 10 star product.
