This was just what I was looking for. Even though I am a good flosser, using this in conjunction with floss makes my mouth feel so good. I mix a little Listerine in with the water and come away with a fresh mouth!
I purchased this after a suggestion from my dentist. I've used it for a couple of weeks and in one sense don't know what it is really doing for me. On the other hand, after using i see little pieces of food in the sink which I hadn't seen nor felt before using. If I floss after using the Waterpik I I don't see any additional particles, so it looks like it does a great job. It is a little messy, but it's just water so no problem. I like to use it when I feel like snacking in the evening instead of giving in. My mouth then feels clean and I don't give in to the urge to snack,,,Ha! Ha! (Unintended benefit!)
