Oral-B iO Series Gentle Care Replacment Brush Head for iO Series Electric Toothbrushes, Black, 4 Count

I found that these brush heads are strong enough to clean my teeth but soft enough not to damage my gums.I don't have sensitive teeth at the moment or a cavity so I don't know how these would feel in these cases.I just wish these brushes had've come with the Oral B IO 8 toothbrush rather than the regular brush heads.I am glad I read the reviews to know to order them along with the toothbrush.

I have sensitive gums and these mske brushing much more comfortable

This toothbrush replaces a mid-priced Phillips toothbrush, which did a decent job until it broke. It took me a while to adapt to this Oral-B, as it’s brush is bulkier than the one I previously used, especially on the cheek side of my teeth. However, it’s action is much stronger than the Philips, so I feel my teeth cleaner for a longer period of time than with my previous toothbrush. The associated app was useful to improve my brushing technique, and is easy to use. Yet, it often fails to identify which teeth I am currently brushing, or which side of my teeth are brushed.

I've been loving my oral b io 5 (the most practical and economical io in the series line up, imo). I wanted to order the gentle brush heads in black and had the hardest time - they sell out just as fast as they restock! Anyway I managed to check and saw they were in stock, ordered, and immediately they were out of stock again. You can see in the photo just how fine and soft the bristles are, perfect for keeping gums healthy! These toothbrushes and brush heads are the best of both worlds - sonic vibrations and at the same time, circular cleaning of the classic Oral B. Definitely recommend!

The round bristles are beneficial and my overall teeth quality is greatly improved. The longevity of the toothbrush replaceable heads are a bit expensive, but of good quality.
