The vibration of the sonic toothbrush seems to really help loosen trapped food and it is very powerful so you dont have to press hard on tender areas to get the job done

The waterpik cleans all the hard to reach spots and even helps apply a little pressure to sore gums after a tightening

The quality leaves a lot to be admired

I have two other waterpik items and i love them however this waterpik is just awful
