The Doctors discuss if applying something meant for your mouth could help with a problem associated with your feet. They weigh in on the idea that mouthwash can be used on your feet to prevent athlete's foot.
"There is theoretically some truth to this," ER physician Dr. Travis Stork says.
He explains that it would depend on which type of mouthwash is used.
Dr. Travis says mouthwashes containing alcohol would act an antiseptic and could kill off bacteria and fungi that result in athlete's foot.
