While a doctor shall prescribe a round of antibiotics and antifungal lotions for the toenails so as to get rid of the infection, which can take days, it is not necessary to visit a doctor to get rid of these horrible infections. A simple course of mouthwash should serve as an effective toenail fungus treatment. Obviously, it does not mean that one has to use the mouthwash to clean the mouth rather use it in a similar fashion daily at least twice a month on your toenails and you should be clear of the fungus in no time.
Reasons as to why a mouthwash solution works with fungus is because it is antiseptic and antifungal in nature meaning that it kills anything that should not be present in the body. Therefore, it can also be used as a lotion for the toenails to get rid of the fungal outgrowths. Furthermore, as the solution is based in alcoholic medium, it evaporates upon contact with the skin and allows the ingredients to migrate deep into the skin.
