I have always used a Water-pik after my dentist recommended I use one when I had bleeding gums and bridgework done. I no longer have problems with my gums and I can clean out any food particles that lodge under the bridgework. So easy to use and I am well pleased with the results.
I was having terrible pain and bleeding because I just couldn't get my teeth and gums clean with toothbrushes, rinses, and floss. I started using the Waterpik and in two weeks my guns were pink and healthy and I was pain free. I also find the device sort of fun and pleasant to use.
