Abstract
Abstract A COMPOSITION ESSENTALLY CONSISTING OF A SUBSTANTIALLY SATURATED AQUEOUS SOLUTION OF CARBON DIOXIDE AND A CARIONIC SURFACE ACTIVE AGENT, IS APPLIED TO THE TEETH DAILY BY A SIMPLE RINSING TECHNIQUE. OPTIONALLY, THE COMPOSITION COULD INCLUDE ETHYL ALCOHOL. PREFERABLY, THE TEETH SHOULD FIRST BE GIVEN A THOROUGH PROPHYLAXIS BY A DENTIST USING A PUMICE PASTE APPLIED WITH A MOTOR-DRIVEN FLEXIBLE CUP IN ORDER TO REMOVE HEAVY ACCUMULATIONS OF DENTAL PLAQUE AND TARTAR THAT MAY BE PRESENT; THEREAFTER, SUCH PROPHYLAXIS SHOULD BE REQUIRED WITH MUCH LESS FREQUENCY THAN HERETOFORE HAS BEEN NECESSARY IF THE NOVEL COMPOSITION IS APPLIED DAILY.
