[This review was collected as part of a promotion.] Oral B always puts out great products and this is no exception! My teeth feel so clean and fresh. These brushes get in between teeth and it feels like they are polished every time. They also are gentle enough for my gums. I feel like my teeth are a bit brighter after using this for a short time.

[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.

[This review was collected as part of a promotion.] I needed new brush heads for my Oral-B electric tooth brush. I decided to try these charcoal re-fills to help whiten my teeth. It will take time to know if they will actually whiten my teeth but I can honestly say that my teeth feel VERY clean after using these new brush heads for about 4 days now.
