Oral hygiene is more than just brushing twice a day. Food particles and plaque often remain between teeth and along the gumline, which can lead to problems if not removed. Traditional string flossing is helpful, but many people find it uncomfortable or difficult to use consistently. That’s where a water flosser becomes a practical solution.
Water flossers use a stream of water to clean between teeth and below the gumline. They are effective at reducing plaque, improving gum health, and making oral care easier for those with braces, implants, or bridges. With so many models available, it can be confusing to choose the right one. To make it easier, we have reviewed 7 of the best water flossers you can buy today, starting with two of the most trusted options.
