The opinions here are mine and mine alone. I have this toothbrush and have had it for years, I'm embarrassed to say that I have not replaced the head in quite a while and now the batteries are dead. But when I did use it I noticed that my gums did not bleed as much and it definitely got more plaque off of my teeth. I have been to the dentist since I have not used an electric toothbrush and they did not have good news for me at all. I am going to go out tomorrow and get another head for that brush and put new batteries in it but, you have to get used to it all over again because it is pretty aggressive pounding on your teeth and gums when you are not used to that. But it is a good way to toughen up your gums so that they do not bleed as easily other times.
