So, I can speak with authority when I say that the best dental hygiene product ever developed by humanity is this tooth brush. I have been using it now for two months and there is absolutely no signs of any plaque! The same goes for my wife. Our teeth are visibly whiter and feel like we just walked out of the dentist's office! I had a few "problem areas" around a poorly fitted crown that hurt when I flossed. After a short time that problem area is a problem area no more!
The toothbrush is also fantastically designed. It really does stay charged for about two weeks (or longer) on a single charge allowing you to completely run out the batteries and switch with the one on the charging base. Not only is this convenient but it extends the life of the batteries.
The only hurdle I had to jump with this tooth brush is that it is so aggressive that my teeth became temporarily sensitive but this went away after two weeks.
So, for everyone out there that hates the scraping, BUY THIS PRODUCT!!!!!!!!!!!!!!
