I've just bought the WP-100 WaterPik on the advice of my dentist. I was not told which one to buy. I did my research on the WP-100 WaterPik and deemed this is right one for from the reviews and the comparison with the other water pik. Anyhow, since I've started using it, I've found the gum was starting to look healthier than before. This is what I've seen so far. I will monitoring it for further gum health improvement.
Did a lot of research regarding water flossing and I'm so happy that I choose the Waterpik flosser. Absolutely love it, a wide variety of tips, and quite easy to use. My teeth and gums feel wonderful since I have been using the Waterpik flosser.
I thought I was getting my mouth clean, by scrubbing and flossing. I was wrong using the water pick and looking at what came out after cleaning was a eye opener. Gums are healthier. Love it.
