 | Author: J. Lesley (United States.. | This product comes in a package which states on the front and the back that it is ONLY for the Philips Sonicare PowerUp battery toothbrush. The product page designation was for *sensitive* but the package I received says *soft*. Whether they are called sensitive or soft these brush heads are absolutely the best for my teeth and gums. The reminder bristles fade so slowly that I forget how dark they are supposed to be so I just keep track of the date and change the brush head every three months. I saw my dental hygienist for the first time since changing over to my new Sonicare PowerUp brush and she said I almost didn't leave any work for her to do. Unfortunately she still said I need to come in every six months. | 4 |
