Mouth ulcers are quite common but getting them persistently can indicate underlying health issues. From stress and anxiety to gastrointestinal disorders, here are a few reasons why you might be getting mouth ulcers frequently. Tap to know!

Stress And Anxiety

Stress and anxiety can lead to inflammation in the body, leading to mouth ulcers or sores, especially if you have a habit of biting your cheeks.

Recurrent Aphthous Stomatitis (RAS)

Recurrent aphthous stomatitis is a chronic condition which can cause persistent painful and round ulcers in the mouth due to nutrient deficiencies, genetics, and more.

Poor Oral Hygiene

Poor oral hygiene, like improper brushing or using harsh mouthwashes can irritate the mouth’s soft tissues and lead to ulcers by allowing bacteria to enter.

Nutritional Deficiencies

If you have any nutritional deficiencies like vitamin B12, folate, iron, and more, they can negatively impact mouth lining, leading to persistent mouth ulcers.

Gastrointestinal Disorders

People suffering from gastrointestinal disorders such as Crohn's disease and more can have inflamed digestive tracts, leading to ulcers in the mouth.
