[This review was collected as part of a promotion.] I replaced my standard brush head with the charcoal brush head about two weeks ago and can already see a difference. I hadn't tried charcoal products before, but have several friends who recommended it. Since, my teeth definitely had a yellow tint from my coffee habit, I decided to give the charcoal brush head a try. I didn't change my toothpaste brand or anything else about my dental routine. At first, I didn't see any noticeable changes, but within a week, I started to notice that my teeth are less yellow. This brush head cleans really well and my mouth feels very fresh after using it. I have now been using it for two weeks and I can see a difference. My teeth weren't overly yellow, but they definitely look a shade or two whiter now. I am excited to see if it continues to improve with use. I am going to try pairing this with a charcoal toothpaste to see if I can get even better results. I definitely recommend trying this to see if it works for you!

[This review was collected as part of a promotion.] Thought Ild give this tooth brush a try. the idea of the charcoal infused brush sounds good. the brush works well as well as a normal oral b tooth brush. teeth look and feel clean. I have using for a month now. But haven't noticed any additional whitening of my teeth yet.

[This review was collected as part of a promotion.] I wanted to try these to see if they helped with some of the coffee and tobacco stains on my teeth. Now i can say that I belive that they did get a little whiter and brighter. The real surprise was how clean they left my teeth and mouth feeling. Ive never used anything that got it this way. I have to belive what I read about the active charcoal is true. It absorbs the gunk instead of just moving it around. I would guess that process stops stuff from sticking to your teeth hence the clean feeling hours later. I could not be happier.

[This review was collected as part of a promotion.] I'm so glad Oral-B came out with these charcoal toothbrush refills! They of course work well with my Oral-B toothbrush, but additionally they offer the whitening benefits of charcoal. The bristles are not too stiff or hard, and unlike charcoal toothpaste, they do not make your teeth black while being used!

Wanted to try these to see if they would whiten my teeth

I 1000% believe the bristles are simply painted black. You would think charcoal would be released so that it could whiten but no, it stays the same no matter how long you use. Nor is there any whitening occurring after months of use

Like the other review says what a waste of money!!! They do not whiten after a week or month etc!! Def not worth the price I will never buy this brush head again going back to the regular ones

[This review was collected as part of a promotion.] I was a bit hesitant to try the Oral-B Charcoal Refills, 2 count, I mean they are dark and I was concerned about dirt for some reason. My husband was the first to use it and said that his teeth, gums and mouth felt really good and clean after he used his first. After my first use, I was just as pleased. If you are unsure, try the single count. I am glad for the two count refill for the both of us.

[This review was collected as part of a promotion.] I really like how this product helps keep my Teeth nice and shiny. I like how clean they feel and look! I do wish they had more than two in a pack. Pretty food product overall. I'd definitely recommend!

[This review was collected as part of a promotion.] I really enjoy this line of Charcoal replacement heads. 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!
