I have always used manual toothbrushes, never an electrical one because of the price. I am very fortunate that Oral B sent me the Oral B 5000 toothbrush to try. I have been using it for 2 weeks now and I love it. I like the way that it flashes red when I press too hard. I tend to brush harder with my manual toothbrushes to get my teeth clean. Now even though I am not pressing too hard with the Oral B 5000, my teeth still feel very clean. I also like that it flashes green after 30 seconds to remind me to brush another section of my teeth. I am not too enthusiastic about the app that was downloaded to my iPhone. After you brush for 2 minutes, it tells you to clean your tongue, then use an oral rinse afterwards. It is good that it gives you feedback on your brushing habits, but I am not comfortable in putting my iPhone near the sink since I do not have much counter space. The app is a bonus, but I probably will not be using it much. Overall, I am happy with the electric toothbrush because it saves me trips to the dentist.
