I find that more stains are removed, it deep cleans, and leaves my smile whiter and brighter. Every morning I brush and it feels like I'm leaving the dentists office! I will continues to repurchase!

[This review was collected as part of a promotion.] I received these charcoal refill packs and I absolutely love how clean they make my teeth feel. I was a tad bit skeptical seeing as it wasn't something you actually had to apply to the toothbrush, but i actually worked and made my teeth whiter and so much brighter.

[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.] I used the charcoal refill on my Oral B toothbrush and I found the charcoal bristles to be difficult to get used to at first but after a couple of times I found them to be acceptable and actually noticed my teeth having a cleaner feel to them.

[This review was collected as part of a promotion.] I have been using the Oral B charcoal refills for the past two weeks and have noticed a lighter shade. While I have used whitening toothpaste in the past, I find that it works more effectively with these charcoal bristles. They really do an effective job.

[This review was collected as part of a promotion.] I got the new Oral B charcoal brushes for my Oral B toothbrush. It was really simple to change the head with the new charcoal head. I like the cup of the toothbrush fit my teeth and cleaned each tooth easily. It was a gentle clean that made my teeth feel clean and almost polished. I have used it for 2 weeks now and I can see a little bit whiter teeth, just by changing the head of my Oral B toothbrush. I am excited to see how two more weeks will clean my teeth. Plus it did not leave a bad taste in my mouth after I used the charcoal refill.
