Dr Ertan Redzepagic used his new pain free device on me a couple of weeks ago to do a root canal (a rather fearsome experience usually). I never felt any pain at all throughout the entire treatment. In fact, I did not have any pain afterwards either – and apart from the area being a little tender in the upper part of my gum ( he had to install a rod to fix my tooth), for a couple of days, it was a trouble free and pain free experience. Thanks heaps for this device.!!!
