Mouth Ulcer Agony: Surprising Triggers Revealed

Mouth ulcers, a common ailment affecting approximately one in five people in the UK, can cause considerable discomfort and distress. While the exact causes are not always clear, contributing factors may include stress, deficiencies in vitamins like B12 and iron, or injury from dental issues. Reader experiences highlight surprising triggers such as Marmite and red wine, suggesting dietary changes can be beneficial for some.

Several everyday products and substances have been identified as potential culprits. Ingredients in toothpaste, like sodium lauryl sulphate (SLS), can irritate oral tissues, while certain foods rich in compounds like theobromine (chocolate) or L-arginine (peanuts) may also provoke ulcers. Even prescription medications for conditions like high blood pressure have been linked to their increased occurrence.

While most ulcers resolve on their own with simple remedies like honey or salt water, it is crucial to be aware of more serious possibilities. Experts strongly advise seeking medical attention if an ulcer persists for more than two weeks, as it could, in rare cases, be an early sign of mouth cancer. Early detection significantly improves treatment outcomes for such conditions.
