Having cleaned my teeth with manual toothbrushes virtually all my life I was amazed at how good a clean you can get from using an electric toothbrush. I was having major problems with my gums and cleaning the hard to reach areas with my regular toothbrush. After an extraction, which was distressing for me and a few sessions with the hygienist she recommended that I purchase an electric brush. The dental practice had an extensive range of Braun Oral-B toothbrushes but they were expensive. I came home, logged on to Amazon and came across the same brush but at a fraction of the price, It only requires charging twice a week and I use it three times a day. With the money I saved I ordered a pack of 4 replacement toothbrush heads. I would highly recommend this brush.
