Oral-B 4000 [SEP] 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!
