How Do You Treat a Mouth Ulcer With Salt?

Treat a mouth ulcer with salt by combining salt and baking soda in a glass of water and swishing it around your mouth, suggests Healthline. After treating the sores with saltwater, avoid any other salty food to keep from exacerbating the problem.

There are other treatments for mouth sores and ulcers, such as dabbing the area with milk of magnesia or a paste made from baking soda, explains Healthline. Topical pastes and oral steroids can help, as well as any number of over-the-counter medications such as benzocaine. Vitamin B6, B12, zinc and folic acid supplements can help to encourage healing. In severe cases, place silver nitrate on the ulcer to cauterize the area. Persistent, chronic and unusually large mouth ulcers can be a sign of a more serious medical condition and should be examined by a physician.

Mouth ulcers can have a range of triggers, from stress and emotional distress to allergic reactions and infections, says Healthline. They can also be caused or exacerbated by acidic foods or sodium lauryl sulfate-based mouth products. Sometimes ulcers are a result of biting your cheek or tongue. In order to prevent ulcers, chew food slowly, do not talk and eat at the same time, limit acidic food intake, and practice good oral hygiene.
