Israeli society Fluorinex Active has come up with a equipment that use an electric current to help keep cavities aside . Using 6 - 9 volts of electrical energy , the fluoride - based colloidal gel that sits in the tray of the gadget is ionized , then forms a protective level over your tooth that should last for 5 whole years .
Though it sounds tantalizing , we wo n’t be seeing this applied science for another year or two at least , but there is a battery - operated variant on the horizon as well . I thought I catch something like this on one of those tardy dark informercial , but I must have been hallucinating .
