Now today was my next dental appointment for looking, and was actually quite impressed with the effect - one would see clearly that the gaps would be blown by regularly, and also the gums would look very healthy. He only advised me also apply the device from the inside, what I'll do now (I have already tried it, it goes a little more difficult than from the outside, but it works).
The tooth cleaning was then so straightforward than ever before.
The Airfloss so was a great success for me! In combination with the Sonicare my teeth now feel optimally cared to.
Addendum (for further 6 months): Now that I do not begrudge my teeth every day a round with the Airfloss from the inside, my dentist was now completely thrilled by my dental care. The combination of Sonicare sonic toothbrush and Airfloss has given me not only super clean teeth with virtually no more tartar, but also a topgesundes gums (which I previously always had problems). Just buy it - I would give the two devices to nothing in the world more. Here I would like to award 10 stars!
