A water flosser is a device that aims a stream of water at the teeth. It's also called an oral irrigator or a dental water jet. A water flosser can help remove food particles between teeth. It also can remove plaque from teeth.
If you use standard dental floss, and you don't have bleeding or other problems, there's no need to change. Using a water flosser can be helpful for people who have braces, other orthodontics or dental work that makes it hard to use standard dental floss. A water flosser also may be useful for people who have trouble flossing by hand. To lower the risk of contamination with bacteria, a water flosser should be used by only one person. Don't share it with other people in your household.
I like water flossers because they're just flat out more fun than regular floss, and so on occasions when I can't be bothered with string floss I'll still normally use the water flosser. You can probably save a few more bucks buying the generic ones off amazon. If I had the space though I'd get one of the ones that plug into the wall. This style is good for travel tho.
