This is the fourth water pik I've owned over the years and if I felt it didn't work a sure wouldn't have had four.I use the water pik along with flossing, brushing and using mouth wash twice a day,I find I need to do all of these things.
I asked my children to chip into a Waterpik as a Christmas gift for me. I have arthritis in my hands and thumbs and flossing is very hard to do. I had my dental appointment today and remarked about my teeth being much cleaner. I also like that the Waterpik has several different attachments.
