This Review Title is Oral-B 4000 and the content is: This Electric Toothbrush was recommended by my Dentist.  One of his reasons was that the vibrating action of the Sonicare brushes loosens fillings.  I have used Sonicare brushes for years and wasn't sure I wanted to change brands.  My current Sonicare wouldn't take a charge anymore so I had to make a decision.  I am very pleased with this Oral-B.  It seems to do everything it claims but I am not convinced it is as effective at flossing as I expected it to be.  During the short time I had to use a regular toothbrush, I noticed my teeth were getting yellower.  Since, I am using this electric toothbrush my "pearly whites" are back to being to being just that!.There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
