An oral irrigator, also known as a water flosser, is a dental device designed to help clean between teeth and along the gum line. It uses a stream of pulsating water to remove food particles and plaque, making it an effective tool for maintaining oral hygiene. Many people use it as a complement to traditional brushing and flossing. Oral irrigators are especially beneficial for individuals with braces, implants, or other dental work, as they can reach areas that traditional floss may miss. They come in various models, including countertop and portable versions, catering to different user needs and preferences.
