I actually look forward to using this toothbrush each time. It leaves your gums and mouth feeling stimulated and fresh. My dentist says my teeth have never been cleaner -- better placque removal than during all the years I used successive Sonicares. The Flexisoft Oral-B brushhead (included in the package) fits well into all crevices and corners, and seems to cup each tooth for a very thorough cleaning. The Polishing brushhead, also included, whitens my teeth as well as any bleaching product I ever tried. I'm happy not to use those bleaching chemicals anymore, and it's great to now be free of the painful sensitivity they caused. Thank you Oral-B for such a superior and well-made product.
