A mouth ulcer can turn eating, drinking and even talking into a wince-inducing chore — and when they keep coming back, it feels like you’re never quite free of them.
If mouth ulcers keep returning, here are the gentle natural remedies people reach for to soothe and support.
Why mouth ulcers keep returning
Recurring ulcers often flare when you’re run down, stressed or a little depleted.
- A run-down system, tiredness and stress lowering your resilience.
- Local irritation, a bite, sharp food or brushing sparking an ulcer.
- A tendency to recur, some people simply get them again and again.
The short version: recurring ulcers flare when you’re run down or irritated, and gentle support soothes and steadies.
