I purchased the Waterpik W-450 to assist in keeping my gum clean from plaque build-up and tartar. This product worked as intended! The instruction booklet was also very clear.
After eating, I thoroughly brushed my teeth with a very soft toothbrush. I then used this Waterpik. I was able to dislodge additional food debris that were trapped near the gum line.
I am highly confident that if I use this product regularly, I should be able to keep my gum healthy. I am also hoping that I would be able to limit my visits to my dentist to only twice a year for routine clean-ups due to healthy gum.
I was torn on which Waterpik to buy and I'm glad I chose the cordless. I've taken it with me for an overnight weekend twice and the battery is stilling going strong. It holds just enough water to get all your teeth done back and front.
