Simple Salt Water Mouthwash Recipe. It’s in fact simple making a personal salt water-based mouth rinse. Add 1/2 a teaspoon of salt to a cup of warm water, as suggested by Adirondack Oral & Maxillofacial Surgery. Rinse your mouth every two to three hours for the first few days after surgery, then use it 3 to four times a day thereafter.

A salt water (saline) rinse can benefit your oral health by cleansing your mouth, warding off infection, and even relieving toothache pain. You can make a salt water rinse at home by mixing a teaspoon of table salt with 8 ounces of lukewarm water. Simply gargle the mixture for 15 to 30 seconds then spit the salt water out.
