This was a Christmas present from me to both my wife and I. Both of us have partial bridges and this waterpik is such an assurance of getting the area under the bridge clean. I've also found it much more comfortable to use than dental floss though I'll still floss but certainly not as vigorously as before.
Several years ago, I was told that I should see a specialist to do surgery on my gums because of "pockets" that were forming. I went out and purchased this waterpik. I have never been told that I need this type of surgery again. My dental visits are fantastic. I would recommend this waterpik highly.
