The Benefits of Saltwater Rinsing for Oral Health.
A saltwater rinse can be used in place of mouthwash and can help relieve a number of conditions, including keeping your mouth clean after a tooth extraction, providing relief for a sore throat, keeping the mouth clean when you have a canker sore, or reducing irritation and inflammation from gum infections or periodontal disease. To do a saltwater rinse at home, mix one teaspoon of salt with eight ounces of lukewarm water and rinse for about 15 to 20 seconds. Spit the saltwater out, rather than swallow it, and aim for a frequency of no more than three or four times a week.
