[This review was collected as part of a promotion.] I used the Oral B charcoal brushes on dentures, did a wonderful job on them . I guess but doesn't matter the brush doesn't know if it's dentures or the real thing . I will definitely be purchasing more replacement brush .

[This review was collected as part of a promotion.] I have been using electric toothbrushes for quite some time now and have yet to find the perfect head - until now. These charcoal refills fit perfectly onto my Oral-B rechargeable handle. I have noticed slight whitening but I haven't used them long enough to see long-term results. This size reminds me a lot of the one at the dentist which brushes each individual tooth. Couldn't be happier with these!

[This review was collected as part of a promotion.] This product is very sensible. We should have discovered this long ago. I went out and bought the brush. I really wanted to try this product. I'm glad I did. The brush head bristles felt so smooth on my teeth.i thought it would have a funny taste,but it didn't.

[This review was collected as part of a promotion.] I have been very hesitant about charcoal products but that changed once i tried the Oral-B charcoal brush heads. The heads are very easy to place on your brush and feel great on my teeth and gums. The bristles are rounded and soft. I drink coffee and tea and the charcoal did a great job of getting rid of staining on my teeth. I am pleased with the ease of the way the brush head works!

[This review was collected as part of a promotion.] I was excited to try this product and shipped fast. It's easy too use and dispose.My family started using this product more because it real helps your teeth and gums remove gunk. Its been a great result using this product.

[This review was collected as part of a promotion.] I love these, they make brushing my teeth more enjoyable because I know I'll have an effectively clean mouth and gums afterwards. They're really easy to attach to the base, and my mouth always feels totally clean and fresh afterwards.

[This review was collected as part of a promotion.] I thought I would try something a little different for my electric toothbrush replacement so I tried these charcoal refills. I can't say I noticed any difference in brushing ability or whitening from these. I would say if you are going for a black color theme in your bathroom then you'll love these. They snapped right into my toothbrush like the other replacements. They did not leave any black bristles in my mouth or otherwise.

[This review was collected as part of a promotion.] I highly recommend this product, Oral-B Charcoal for natural whitening. This product is a 2 pack replacement brush head refill for my Oral-B toothbrush. These refill pack brush heads are interchangeable for most Oral-B toothbrushes. After this product, my teeth are so much whiter than before. I have noticed coffee and tea stains removed. I drink coffee and tea daily, so my teeth seem to get a yellowish tint very easily. After using this product, my teeth are definitely whiter and the yellow stains removed. It may take a while to get used to the charcoal color of your teeth, at first though. I love this product!

[This review was collected as part of a promotion.] This charcoal brush refill cleans my teeth and brightens them. It helps remove my coffee and tea stains as I like to drink a lot of coffee. It is very easy to use. The round brush helps clean my teeth one at a time so it covers the whole tooth.

[This review was collected as part of a promotion.] I started using the Oral-B Charcoal Refills on my brush a few weeks ago. I am a fan of charcoal toothpaste and tooth powder already, but since using these on my Oral B brush, I have noticed an improvement of the color of my teeth. They seem to be whiter and brighter then when I use other charcoal products. The bristles are really nice, not aggressive at all on my teeth and gums, which is very important to me. I have not experienced any issues or sensitivity since using these refills on my brush. I will be buying more for my family to use.
