Last week I replaced my falling-apart Sonicare toothbrush with one of the Oral-B/Braun models and I am much more pleased with it than with Sonicare, which I’ve used for several years. It’s an all-around better experience. I’m using one of the brush-heads that’s described as being like flossing as well as brushing, though I’m still flossing once a day, too.
These high-speed electric brushes work a lot better than a traditional toothbrush; they are a good investment.
(P.S. I still use a very old Sonicare brush to brush my ‘night guard’. It’s the newer model that’s falling apart and also, I might say, harder to keep clean than the original.)
