I am thrilled, my teeth have become much brighter and all deposits are grants away. This saves the Zehnreinuigung the dentist. I had to a gum treatment still every now and then bleeding gums, which is now completely gone. I use the brush in combination with an oral irrigator and the toothpaste of Emmi.
I have every now and then checked with dental floss if all interdental spaces are clean and never found residues.
I can only recommend everyone to buy this ultrasonic toothbrush, it is worth the money!
