Used to soothe canker sores, gum irritation, or minor mouth injuries when commercial mouthwash or medicated rinses are not available.
Sodium bicarbonate (baking soda) helps neutralize acids in the mouth and reduce inflammation, promoting faster healing of mouth ulcers, sore gums, or irritation caused by stress, illness, or rough food. This rinse is safe, shelf-stable, and can be used multiple times daily to ease discomfort in the field or during long-term emergencies.
Ingredients
- ½ teaspoon sodium bicarbonate (baking soda)
- 1 cup clean, lukewarm water (boiled or purified if needed)
- Optional: pinch of sea salt (for added soothing and cleansing)
How to Use It
- Mix baking soda (and optional salt) into the water until dissolved
- Swish gently in the mouth for 30–60 seconds
- Spit out — do not swallow
- Use 2–3 times daily as needed, especially after meals or before bed
Warnings
- Do not swallow the rinse — it’s for external (oral) use only
- Discontinue if pain worsens or if infection signs appear
