I bought this to help with gum disease problem and it has eliminated it completely. I can't imagine my life without it. That sounds over the top but seriously, I feel my mouth has never been healthier. The food particles that come out after I have brushed my teeth is unbelievable. I strongly recommend this product. Too new to tell about longevity of the life of this machine, but I would be happy with 3 years. LOVE IT!
Bought this a month ago to aid in clearing up gum infections. After using it in the AM for three days the infection had improved and the gums were starting to look normal. I use it every afternoon or evening and the overall appearance of gums and teeth continue to improve.
Due to periodontal issues, my dentaist highly recommended I start using a water pik. Took some getting used to. Will see how it's helping at my next visit to the dentist. So far so good as far as I can tell.
