Never want to go back to plastic brush heads ever again!
I have just begun using the primal life organics toothbrush and heads and let me tell you.... I never want to go back to the hard plastic toothbrushes. No wonder I could never brush my teeth well enough close enough to the gums and was getting erosion (and I'm only in my mid - twenties). Now I can comfortably brush my teeth and feel like I am covering all the parts of my mouth the best I can... and with no gum pain or sensitivity. Absolutely amazing!!
