I nearly didn't purchase a Waterpik due to some of the negative reviews. I'm glad that I disregarded them. I have experienced none of the problems people complained about. After only a few weeks of use my mouth and gums feel better. My only regret is not purchasing and using a Waterpik years ago.
Bought our water pic about a month ago as recommend by our dentist. Our teeth look and feel so clean. The grandkids had to try it too. (Guess what they are getting for Christmas!)
I bought my Waterpik last month for my new braces. I was a little nervous about using it at first, but it works great! It keeps my mouth feeling fresh and clean every time I brush. It really helps get out the food I can't see! It's quiet, and I really like the option for adjusting pressure. So just be careful when trying to find what works for you!!
