2. How often should the nozzle of a water flosser be replaced?
A water flosser can be used daily, but it is not recommended to use it multiple times a day. Although water flossers have a relatively long service life, their nozzles—just like the brush heads on electric toothbrushes—also have a limited lifespan. It is recommended to replace the water flosser nozzle every 3–6 months, depending on the volume of use. In high-traffic settings, replacement is generally needed after about three months. If the device is used less frequently, the nozzle can be replaced every six months; however, failing to replace it for an extended period may affect its cleaning effectiveness.
