Toothbrush heads are very small feels like you’re brushing with a child’s toothbrush.
I would recommend this to a friend!

The toothbrush head is designed to be small to fit in the back of your mouth at the correct angle for flossing. If you're interested in a full-size brush head, click here for more information: https://www.waterpik.com/oral-health/tips-accessories/SFFB-2EW/
I am enjoying my sonic fusion. My teeth are super clean. I like the compact housing that fits comfortably on my counter top. The two in one feature is a plus too, as it is all at my fingertips.
