[This review was collected as part of a promotion.] I saw these Oral B whitening heads and decided to give them a try. I had my doubts about the total ly black bristles and the whitening claim. After using them for a week I believe that they are working. As time goes by the results will hopefully be good.

[This review was collected as part of a promotion.] My teeth feel really clean after brushing with these. It is a very firm tooth brush which is not my favorite I prefer a soft brush but it really helps to make your teeth feel clean and it has whitened my teeth a little bit in the two days of using it.
