I was having problems with gums even with brushing, flossing and mouthwash three times per day. Started using the Waterpik and within three days, symptoms were gone. I now use it after each meal just to keep on top of any relapse. Fast and easy to use so nothing has a chance to remain between teeth.
I bought this before leaving on 3 week vacation and never opened until I returned. I had continued to use old Water Pic and glad I did whilevaway. I find new model very cumbersome and truly wish I had not purchased it. The old model far easier to use, especially in light of the fact I am a senior citizen.
