[This review was submitted after receiving an incentive.] Great pack of 4 toothbrush heads. Whiter teeth by removing surface stains. Nice design. Advanced technology, round head, gentle micro vibrations.

[This review was submitted after receiving an incentive.] I confess to being doubtful about this new product, - would it clean and offer anything more than my normal iO heads? I was pleasantly surprised! The new Radiant White head seems to leave a very smooth finish to my teeth, just like after I've visited my hygenist. I'm impressed.

[This review was submitted after receiving an incentive.] I've been using an Oral-B iO 4 toothbrush, combined with a gentle care head for a while now, but this is my first time trying a Radiant White head. I found the radiant white head did actually improve a bad stain on one of my teeth, which was great. However, I usually use gentle care heads, because I have poor gums and sensory issues regarding the vibrations of the brush. The new radiant white brush seemed much firmer and the vibrations seemed harsher. So on the whole the radiant white heads are great, but this sensitive sole will continue to use my gentle care heads for every day use and switch to the radiant white heads if I have a special event to attend and want to impress.

[This review was submitted after receiving an incentive.] These heads are good for cleaning all areas and preventing future stains, may not vanish any older longer stains but definitely do a good job of cleaning your teeth. Teeth and mouth feel great

[This review was submitted after receiving an incentive.] These are brilliant and easy to attach to my toothbrush I like how they cleaned my teeth and much prefer these black head versions

[This review was submitted after receiving an incentive.] I've been using an Oral-B iO toothbrush for a while now, but this is my first time trying the Radiant White heads. They give a really thorough clean -- my teeth feel super smooth and fresh after brushing, which I love. However, I haven't noticed any real difference in the whiteness of my teeth compared to the standard iO heads. Overall, they do a great job at cleaning, but I'm not sure the whitening claim makes much of a difference for me.

[This review was submitted after receiving an incentive.] I've been using an iO brush for a while now and have used the standard heads and found them to leave your teeth really clean. I was sent a sample of these from Savvy Circle so was obviously keen to try them. Unfortunately I've not been as impressed by them as they claim to whiten within a day however after using them for almost 2 weeks I've not seen any difference whiteness wise. My teeth definitely feel clean, however no different to the standard iO brushes I've use before. The brush also feels a little harder on your teeth with the petals, so it may be an uncomfortable for people with sensory issues. They come in a pack of 4 and my husband and children (aged 12 and 9) have also tried them and they also haven't experienced any difference with whitening of their teeth. In all it's a good brush head for cleanliness but not for the whitening as it claims.

[This review was submitted after receiving an incentive.] These toothbrush heads are the best. I was very happy to be selected for the toothbrush and you don't even know how happy my daughter was. She goes to brush her teeth every night without me asking for it now, as she wants to use the toothbrush. She loves it and she is not even scared of it like she was when using another brand. It doesn't make too much noise and cleans so well.

[This review was submitted after receiving an incentive.] After using the brush heads for around 2 weeks, I have found them to be brilliant! As always the Oral B iO leaves my mouth feeling squeaky clean, but now they're squeaky clean and a bit brighter looking, what more could you want?!

[This review was submitted after receiving an incentive.] I noticed a difference after the first use, my teeth felt and looked cleaner. I brush twice a day and after using for over a week I love how whiter my teeth now look. I think this will be my regular brush from now on.
