how do you get mouth ulcers

Mouth ulcers (often called canker sores) usually come from irritation, minor injury, or changes in your body that make the lining of your mouth more fragile and inflamed. They are common, usually harmless, and tend to heal on their own within 1–2 weeks.

What mouth ulcers are

• Mouth ulcers are small, painful breaks in the lining inside your mouth, often on the cheeks, lips, tongue, or gums.

• They can be round or oval, typically pale or yellow in the center with a red border, and can sting when you eat, drink, or brush.

Common everyday triggers

• Minor injury : Biting your cheek or tongue, brushing too hard, sharp or broken teeth, braces, dentures, or hard/crispy foods (like toast or chips) can damage the lining and lead to ulcers.

• Burns from hot food or drinks, or rough fillings, also commonly trigger a sore spot that becomes an ulcer.

Body and lifestyle factors

• Stress, tiredness, and hormonal changes can lower your mouth’s defenses and make ulcers more likely.

• Lack of nutrients like iron, vitamin B12, folate, or zinc is linked with recurring mouth ulcers in some people.

Foods, products, and medicines

• Some people get ulcers after certain foods such as citrus fruits, chocolate, nuts, spicy foods, coffee, or gluten-containing foods if they are sensitive.

• Toothpastes or mouthwashes with sodium lauryl sulphate (the foaming agent) and some medicines or medical treatments can also irritate and trigger ulcers.

When it’s a sign of something else

• Frequent or unusually severe ulcers can be associated with conditions like coeliac disease, Crohn’s disease, Behçet’s disease, and immune problems.

• If ulcers last longer than about 2–3 weeks, keep coming back, are very large, or you feel unwell (fever, weight loss, swollen glands), a doctor or dentist should check for underlying issues.
