I ordered my first Waterpik several years ago. Since my water is hard, it became a little crusty over time. So I decided to replace it since I find Waterpik to be indispensable to maintaining my oral hygiene.
bought this about one month ago on dental hygenist's recommendation, as I have several crowns. Easy to use - a little on the noisy side but it doesn't take long to complete the task.
I had been having problems with bleeding gums over one tooth which also had a receding gum pocket. after 4 days of use, the bleeding stopped. the gum pocket has gone away. my gum is back to normal. when I use it I put a cap of mounth wash and a cap of peroxide in the water and use 2-3 times a day. awesome results.
