Does using a water flosser help with oral care?

Yes, a water flosser helps remove food debris from between the teeth and along the gum line, where a toothbrush struggles to reach. It is especially useful for 1) people wearing orthodontic appliances, 2) people with restorations such as implants or bridges, and 3) people with wide spaces between the teeth where food gets caught. However, plaque that clings to the tooth surface is not removed by a water jet alone, so it cannot replace brushing and flossing and should be used as an aid.
