A new product for us. Oral-B added this charcoal model and we began using this over the New Year timeframe. So far, very happy but cannot verify the whitening powers yet since the short timeframe. Brush heads seem to have the very good bristles on the regular versions and are holding up well, with some loss of charcoal with each use. Should update this review after a few months to establish a true whitening comparison

Great! Wonderful! I'm a coffee drinker. So, stained teeth. These charcoal heads make a difference. Whiter teeth in just a few brushes! And, I swear my breath is better. I found regular toothbrushes in the charcoal too. (Not at Sams). I bought them for my family and they love them. I'm sure Sams will be carrying them soon. These charcoal heads are must for whiter teeth!

This item works great. I was skeptical at first, but noticed a difference within a week.

I wasn't sure I was going to like these but they sure did brighten my smile. And got rid of some of the stains that have been there a while.

I have been using an Oral B electric toothbrush for years and had great results, but this new brush head takes brushing to a higher level. My teeth seem cleaner, my mouth is fresher feeling, and the experience is more pleasant.

Bought these refills for daughter and son in law for the Oral B electric toothbrushes I gave to them last year for Christmas. They loved them! Good buy too as I bought them on sale.

Work very well on stains.

I don't know about the whitening of the teeth because of toothpaste I use or if I haven't brushed with this type of head before, but it does make make teeth feel clean and is easy on the gums.

These are nothing except a different color. You are better off with the ones for gum health. They haven't added any.

I doubt these are really charcoal , and think they are jysg dyed black bristles . When I use them no charcoal is transferred from the brush as it would happen with real charcoal .
