This is my third waterpik product. So much easier to use the portable model. The only sort of complaint is that I sometimes have difficulty removing the reservoir.
I bought this two weeks ago. I had a spot between two teeth that would bleed really bad after cleaning with a toothpick. After two weeks I couldn't even get it to bleed today. It works !!!
I have never flossed on a regular basis because my teeth are so close together that the floss would break during the flossing process. My dentist recommended that I use a "water flossing" device in addition to regular flossing so I could clean out deep pockets around my teeth that regular floss could not reach. I have noticed that the Waterpik, used after regular flossing, really does remove additional bits of food.
I bought this on the recommendation of my dental hygienist. I love it. I use in the shower each morning. I hope my hygienist sees an improvement in my gum health at my next checkup.
