Mayo Clinic: Oral Irrigators should not replace brushing, flossing.

“Healthy Lifestyle” blog considers whether flossing or an oral irrigator is more effective for cleaning “the tight spaces between the teeth.” Although oral irrigators can be effective in removing food particles from teeth, Mayo Clinic advises, “If plain dental floss gets stuck in your teeth, use the waxed variety. If you have a hard time handling dental floss, try a floss holder.”
