Myth 5: A little swish’ll do ya
Do you gargle or rinse for a few quick seconds, then spit? Most mouthwashes are at their most effective when in contact with your mouth tissues for 30 seconds per use. But despite best intentions, some people say mouthwash is so strong or stings so much that it’s difficult to use for that long. Still, it’s worth sticking it out if you want the best results. “Mouthwash should be used as directed by the manufacturer,” says Dr. Swan.
