Baking soda can help soothe mouth sores by reducing acidity and easing stinging when used as a mild rinse. It is helpful for temporary relief, but sores that are severe, recurring, or not improving need professional care.

- Gentle rinse works best: A diluted baking soda rinse is usually safer than direct powder application.
- Relief is limited: It may calm burning, but it does not fix the root cause of every.
- Watch for red flags: Fever, swelling, spreading ulcers, or sores lasting over two weeks need evaluation.
- Kitchen habits matter: Acidic foods, heat, dryness, and friction can make sores worse.
- Prevention helps: Soft brushing, hydration, and trigger awareness can reduce future irritation.
