Several years ago I bought the water pike for my son to use for his braces. There was attachments included in the price that would help reduce plaque buildup and periodontal disease - which I use. When I went for my annual cleaning, the hygienist was impressed of how healthy my gums were.
I am delighted with the power and all of the optional heads that come with this unit. It is so easy to use and so effective at cleaning my teeth at the gum line. I also like the small footprint, so I can leave it on my bathroom counter.
