I have a water Water Pic science the late 1990's. Have never had a cavity while use. Do brush teeth regularly, but believe this was a major cleaning tool.
I bought this product six months ago after getting braces. Flossing was difficult and time consuming with braces. After using this the first time I was very pleased. I don't have to floss when using this waterpik. I even take it with me on vacation. Excellent product.
My dentist's hygienist recommended the Waterpik to fight tartar and help my gum health. I remembered Water Piks Fromm years ago. They were not easy to use. I decided to purchase one and give a try. To my surprise it was easy to set up and use. It works well and my gums and teeth are much better.
I bought my waterflosser a month ago, my mouth and gums are so healthy it is the best investment for my mouth, according to my dentist. Every body should have one.
I bought this after having periodontal work done at great expense and found it to really keep my teeth, gums and mouth cleaner than just brushing, rinsing and using floss.
