[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.] Your teeth feel amazing after using the charcoal brush head. The design lets you clean each tooth. I like that as it makes me feel that I am doing a better job at cleaning. Easy to change out and replace the head. Overall great product.

[This review was collected as part of a promotion.] Hi received the Oral B Charcoal Toothbrush Refills from the Try It Community. They have really made my mouth feel much cleaner. I love brushing my teeth with them. They feel cleaner and my breath seems better since I started using them. The only problem is that the bristles are already starting to fall apart. Other than that, I really like them.

[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.] My teeth feel super clean after using the charcoal brush heads! I love how smooth my teeth are, you can tell how well it removes plague and build up. I will buy these from now on instead of my usual 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!
