We all know the classic image of a small cap filled with vibrant green or blue mouthwash, but have you ever considered using plain saltwater as a substitute?
George Doyle/Valueline/ThinkstockPerhaps your mother once advised you to gargle with saltwater to soothe a mouth sore. Or your dentist recommended a warm saltwater rinse after a tooth extraction. Maybe you’ve even tried it as a remedy for bad breath. But does it truly work for these purposes? Can saltwater really address your oral health issues?
Historical records reveal that saltwater rinses have been in use since ancient times. Evidence of treating gum disease with saltwater dates back to 2700 B.C. in China. Pliny the Elder, a Roman author, naturalist, and naval commander (A.D. 23-79), reportedly advocated its use among Rome’s elite as part of their oral hygiene routine [source: Rupesh].
A 2010 study conducted in India with 45 participants found that saltwater remains an effective method for eliminating oral bacteria. A saturated saline solution—made by dissolving 9 teaspoons of salt in 2/3 cup of water, the maximum amount of salt the water can hold—kills bacteria by dehydrating it when used daily [source: Rupesh]. This solution targets oral bacteria linked to conditions like gingivitis, a type of gum disease, and halitosis, commonly known as bad breath.
Dentists frequently suggest saltwater rinses to alleviate swelling and discomfort caused by tooth extractions or mouth sores, such as canker sores. An Australian dentist notes that saltwater rinses are beneficial post-tooth extraction as they help reduce inflammation. However, he advises against daily use, warning that the acidity of saltwater can erode tooth enamel and lead to decay [source: Kerr].
The American Dental Association (ADA) acknowledges that saltwater can temporarily mask bad breath but does not endorse it as a permanent solution [source: Mouthrinses]. Chronic bad breath can stem from various causes, including periodontal disease or bacterial buildup on the tongue. If regular brushing and flossing don’t resolve the issue, consulting a dentist is recommended [source: Bad Breath].
