Mouth ulcers, also called canker sores, are small painful sores that appear inside the mouth on the gums, tongue, or inner cheeks. While occasional ulcers are normal, frequent mouth ulcers can signal an underlying health issue. Understanding the causes and taking preventive steps can help keep them away and reduce discomfort.
1 Nutritional Deficiencies
Lack of essential vitamins and minerals like Vitamin B12 Iron and Folate can lead to frequent mouth ulcers. These nutrients are important for maintaining oral health and their deficiency makes the tissues in the mouth more prone to ulcers. Eat leafy greens dairy products eggs nuts and whole grains. Consider taking supplements if recommended by a doctor.
2 Stress and Anxiety

High stress and anxiety levels weaken the immune system and trigger mouth ulcers. Stress hormones can make the mouth more sensitive and prone to inflammation. Practice relaxation techniques like meditation yoga or deep breathing exercises. Get enough sleep and manage daily stress effectively.
3 Injury or Trauma to the Mouth

Accidentally biting the inner cheeks using a hard toothbrush or irritation from braces and dentures can cause small wounds leading to ulcers. Use a soft-bristled toothbrush and brush gently. Be mindful when eating to avoid biting the cheeks.
4 Hormonal Changes
Women often experience mouth ulcers due to hormonal shifts during menstruation pregnancy or menopause. Maintain a healthy diet and seek medical advice if hormonal imbalances are affecting your oral health.
5 Food Sensitivities and Allergies
Certain foods like citrus fruits spicy foods coffee and chocolate can irritate the mouth and lead to ulcers. People with gluten intolerance or lactose sensitivity may also be more prone to mouth sores. Identify and avoid foods that trigger ulcers. Keep a food diary to track and manage your diet accordingly.
6 Weakened Immune System

Health conditions like autoimmune diseases diabetes or HIV can make the body more susceptible to frequent ulcers. Boost your immune system with a balanced diet regular exercise and good hydration. Seek medical advice for underlying health conditions.
7 Oral Infections and Poor Hygiene

Bacterial viral or fungal infections in the mouth like herpes simplex virus or oral thrush can cause ulcers. Poor oral hygiene also increases the risk. Maintain good oral hygiene by brushing twice daily and using an antibacterial mouthwash. Avoid sharing personal items like utensils with others.
8 Side Effects of Medications
Certain medicines like pain relievers beta-blockers and chemotherapy drugs can cause mouth ulcers. Long-term use of NSAIDs can also irritate the mouth lining. If a medication is causing ulcers consult a doctor for alternatives. Drink plenty of water and use soothing mouth gels if needed.
9 Acidic and Spicy Foods

Eating too much acidic spicy or salty food can irritate the mouth lining making it more vulnerable to ulcers. Reduce acidic foods like lemons tomatoes and vinegar. Eat more alkaline foods such as cucumbers bananas and yogurt to maintain a balanced pH in the mouth.
10 Dehydration and Dry Mouth

A lack of hydration leads to dry mouth which reduces saliva production and makes the tissues in the mouth more prone to irritation. Drink plenty of water throughout the day. Use a humidifier in dry environments to keep moisture levels balanced.
