Hi...., Gargle saltwater. A saltwater gargle of 1 teaspoon. Gargle the solution and then spit it out.... Consider lozenges. Lozenges can soothe a sore throat.... Brush your tongue. Your tongue harbors bacteria, so carefully brushing it may help reduce odors.... Brush your teeth after you eat.... Floss at least once a day. Proper flossing removes food particles and plaque from between your teeth, helping to control bad breath.....
