I'd keep traditional floss handy, just in case.
I'm torn, here as I feel like I still get a better floss with regular floss. I'm not saying this doesn't work, it does a great job getting particles that are stuck between your teeth. It just feels like I need that friction from the string to really feel clean. What this does a fantastic job at is getting those little white chunks that you may or may not have that are stuck in your throat when you are sick. Those little gems (commonly called tonsil stones) are very uncomfortable, but this water flosser does a fine job breaking it up and making easier to remove/come out. There are several attachments that come with, and each serve a purpose for particular cleaning. The bottle water tanks holds a fair bit of water as well, I like to warm my water just slightly, feels a bit better. Also, your mouth will fill with water so make sure you do this over a sink, unless you like messes.
