Query: Does NOT get in between teeth. Should rename.

I have both Oral B Vitality Dual Clean & Oral B Vitality Sonic. The Sonic & Dual Clean Vitality brush heads DO get in between teeth. They are like using a flat head manual toothbrush THAT DO CLEAN your teeth well.THE FLOSS ACTION IS POINTLESS, since it WON'T get in between your teeth.The top of the brush head sticks out/ too long in depth. It hits our teeth when brushing in an average way; be prepared to open wide to avoid the tooth hitting. DON'T forget to floss separately.
