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!!
I've been putting off buying and using the Waterpik, but now that I have it, I wish I started sooner. It's great and really keeping me plaque-free. Much more thorough than flossing, but I continue to floss.
