What is the difference with a round brush head?

There are simply two kinds of electric toothbrushes available on the market: with a round brush head and with an oblong brush head. The round brush head usually makes a rotating and pulsating movement and makes it possible to clean each tooth separately. The oblong brush head of SonicYou is different. This toothbrush has long bristles that make a back and forth (sonic) movement, cleaning your teeth deeply and thoroughly. Our brush head is shaped like the head of a manual toothbrush and is designed to clean in a similar way.
