The Sonicare aims to clean between teeth. It sends a jet of air or liquid. The jet is powerful enough, but it is not unpleasant or harmful. Personally I add the small tank mouthwash a known brand that keeps the dentine resistant to acids. In this way the space between the teeth is also protected. There are 3 three cannulas for different users. Personally I used one and after two months of not charging. I really do not know where does this problem. In summary, the last 3 days I nutilise over this unit, I miss it !!! If you value your teeth and you can invest in this purchase, I strongly advice you.
