Love this toothbrush! The bristles are like floss and get in between the teeth. Be prepared for this and start gently, or you’ll likely have bleeding gums! Don’t worry, your gums get used to it. Excellent in getting the mouth feeling clean. Love the feel of the bamboo. My only negative is the longevity of the handle. It tends to splinter with use from repeated water exposure. To be expected since its wooden, so hoping this lasts 3 months. I’ll be replacing this more than a typical plastic brush, but worth it for both hygiene and eco reasons!
