I am amazed at the amount of "stuff" that comes out of my mouth when I use it. I feel good knowing that all of that is exiting the premise rather than doing its dirty work in my mouth.
We had an old water pik that was purchased for my husband and never used. I pulled it out when I got braces as an older adult to start using it. It worked fine but was noisy. It died after a few months and I bought this one as a replacement. Wow - what a difference the improved features made! It's quieter and easier to use by far. The reservoir has a lid so my cats don't drink whatever water is left in it. it's easier to store the pik in between uses. Not only is it quieter but the on/off button is easier to find by feel while flossing. The old water pik was so loud that my cats wouldn't stay anywhere near it (they follow me everywhere I go) but this one is so quiet that the cat will drink out of the faucet while I lean over the sink using the water pik (only cat people will understand this). It came with a range of tips, one of which is designed specifically for braces, which I appreciate. And there is storage for (most of) the tips in the lid (I just put the one or two extras on top of the others, even though there wasn't a specific slot for them, and closed the lid). It's so easy to use I use it several times every day.
My dentist recommended this waterpik. It is easy to set up and use. I look forward to using it. It has greatly improved the overall health and appearance of my teeth and gums. It removes all the food particles out between my teeth. I use the waterpic 3 times every day.
