Recurrent Mouth Ulcers: Nutrition and Vitamin Deficiencies

Overview

Mouth ulcers are painful sores inside the mouth. Most heal, but persistent or frequently recurring ulcers need assessment.

How should results or symptoms be assessed?

Local trauma, stress and some foods may aggravate sores. Iron, vitamin B12 or folate deficiency can contribute in some people; not every ulcer reflects a deficiency.

Practical next steps

Choose soft, less acidic foods while the mouth is sore and drink enough fluids. Limit rough, very hot or irritating foods and seek dental or medical advice for recurrence.

When is medical help needed?

A sore lasting more than two weeks, swallowing difficulty, unexplained weight loss or widespread symptoms should be examined promptly.
