I bought this a couple weeks ago on the recommendation of my dentist. It takes a little while to get used to it. Hopefully, with daily use I will improve my gums.
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.
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!
