[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 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.] 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 am super into natural products and the use of charcoal in these heads is amazing! They are same quality you expect from your Oral-B heads with an added benefit that makes using them even better. I am so pleased with these.

[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.

[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 like the added features of charcoal on the brush head. Fits most oralb toothbrushes and works for a good amount of time before changing them out. Does a good job at cleaning and helps keep teeth whitened.

[This review was collected as part of a promotion.] I received Oral-B Charcoal Electric Toothbrush Replacement Brush Heads Refill, 2-Count and they are great at cleaning as well as whitening tea and coffee stains. I really love how smooth and clean my teeth are after brushing and how white and bright my teeth are looking after using this product.

[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 .
