My dentist recommended I get water device because my teeth are close together and hard to floss. Although it was a bit messy at first (remember to put it in your mouth before you turn it on), I noticed how clean my mouth feels after I use it. Also, I think my teeth look whiter.
Makes your mouth feel as clean as when you visit the dentist. Had started having gum problems with slight bleeding after two weeks of consistent use, gums have stopped bleeding and swelling has gone down also. Gums look healthier and teeth feel cleaner. Great product!
I bought this WP-100 as a replacement for a unit that I wore out (over ten years old). It is perfect with all the different attachments that come with it.
