Using a mild salt-water mouth rinse
A simple salt-water rinse may make a small ulcer more comfortable for some adults.
A little context: this note is for adults with mild symptoms. Pregnancy, long-term conditions, or reduced immunity can change what is safe. Ask a professional if you’re unsure.
Let’s start here
A simple salt-water rinse may make a small ulcer more comfortable for some adults. It should be mild, comfortably warm and spat out after use.
A few small things to try
- Mix a mild rinse in a clean glass
- Rinse gently and spit it out
- Stop if the rinse causes discomfort
Keep eating and cleaning comfortable
Dissolve half a teaspoon of salt in a glass of warm water, let it reach a comfortable temperature and rinse gently. Spit the solution out rather than swallowing it. If it stings, stop; stronger salt mixtures are not a way to speed healing or disinfect the mouth more effectively.
Follow-through and limits
Prepare a fresh rinse in a clean glass and keep it away from children. This is a comfort measure, not a cure for every mouth sore. A persistent, bleeding or unusual ulcer still needs examination, and difficulty swallowing requires advice rather than repeated attempts to rinse.
A small familiar mouth ulcer often settles within one to two weeks. Gentle oral hygiene and avoiding things that sting may improve comfort while it heals. A pharmacist can discuss a suitable treatment, but unexplained or persistent sores need examination rather than repeated self-treatment.
A couple of things to skip
- Do not put aspirin, undiluted peroxide or other harsh chemicals on an ulcer.
- Do not ignore a persistent sore or use someone else’s prescription mouth treatment.
When to ask for help
See a dentist or clinician for any ulcer lasting longer than three weeks, one that is unusually large or different, bleeding or worsening pain. Seek earlier help if you cannot drink, have fever, repeated multiple ulcers or sores elsewhere. Trouble breathing or swallowing needs urgent emergency assessment.
If symptoms are severe or rapidly worsening, use your local emergency service. A little more on getting help.
