I bought this Waterpik 2 months ago and itis a very good product. I have several crowns and it cleans them better than flossing or using an electric toothbrush. I'm very pleased!
I have a bad deteriorating set of teeth. The dentist recommended that I start using a mixture of water and non- alcohol mouth wash along with my regular flossing because of some holes in my gums and the fact of having had my teeth accidentally radiated during Chemo. The new Water Pick forces plaque and other remains from eating out so I now have a cleaner mouth and easier checkups.
I bought my first Waterpik around 1980 and just purchased my 3rd unit. Never expected to have braces as a Sr. Citizen! Love my new WP-100, I truly could not get along without this part of orthodontic and periodontal care. I even bought one for my neighbor girl who recently got braces, too. Love it!
