[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 started using these about a week ago and can already see a noticeable difference. My coffee stains have been slowly vanishing with the use of these charcoal brush-heads. I would highly recommend these to someone looking to brighten their smile!

[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.] I love these replacement toothbrush heads! I can actually tell that they are whitening my teeth and they clean a lot better than the ones I usually use. I will definitely continue to purchase these in the future.

[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.

[This review was collected as part of a promotion.] Great product! charcoal Seems to be the trend for whiter teeth. I was nervous about trying and I have already noticed a difference. I'll keep buying these replacements! My husband is a huge fan as well.

[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.] Not too sure if they made my teeth whiter, but I love the way my Oral-B Charcoal brushes make my teeth feel like I've just come from the dentist for a cleaning! Have used my rechargeable Oral-B Brush for many years and dentist has said that my teeth and gums have never looked better! Love all of Oral-B products
