I know I am doing the best I can to preserve my teeth, permanent bridges etc. And flosser has several different speeds---mouth feels sparkling clean when I am done!
I bought one just like this one a few years ago. It finally bit the dust and had to replace it. Found the sMe one and was so happy. It has great features and so easy to use.
This is my second waterpik. I bought my first one almost 20 years ago when I had an accident and broke my machine. I love the way it cleans my mouth, teeth and gums and especially cleans my very expensive dental work.
