Estimated reading time: 4 min


Mouth ulcers, also known as canker sores or aphthous ulcers, are shallow, painful sores that can develop inside the mouth. They often appear as round or oval lesions with a white or yellowish center and a red border. Mouth ulcers can occur on the inside of the lips, cheeks, tongue, and on the gums. While they are usually harmless and resolve on their own within one to two weeks, they can be uncomfortable and make activities such as eating and talking painful.

In most cases, mouth ulcers heal on their own within one to two weeks without scarring. However, larger or more persistent ulcers may require medical attention.

Some people may experience recurrent mouth ulcers, which can be associated with conditions like recurrent aphthous stomatitis (RAS). If someone experiences frequent or severe mouth ulcers, it’s advisable to consult a healthcare professional for further evaluation.


1. Size and Shape: Mouth ulcers are typically small, ranging from a few millimeters to about a centimeter in diameter. They can have a round or oval shape.

2. Color: The center of the ulcer is often whitish or yellowish, surrounded by a red border. The area around the ulcer may also appear inflamed.

3. Pain: Mouth ulcers can be quite painful, especially when eating, drinking, or brushing teeth. The level of pain can vary from person to person and depends on the size and location of the ulcer.


The treatment of mouth ulcers typically aims to alleviate symptoms, promote healing, and prevent complications. Here are some common treatments for mouth ulcers:

1. Topical Analgesics and Anesthetics

2. Pain Relief Medications

3. Oral Rinses
Rinsing the mouth with a saltwater solution or an antiseptic mouthwash can help keep the ulcer clean and promote healing. Avoid alcohol-based mouthwashes, as they can be irritating.

4. Avoiding Irritants
Identify and avoid foods and substances that may irritate the mouth, such as spicy or acidic foods, tobacco, and alcohol.

5. Nutritional Supplements:
If the ulcers are associated with nutritional deficiencies, supplements of vitamins and minerals such as B12, iron, folic acid, and zinc may be recommended.

6. Maintaining Oral Hygiene:
Good oral hygiene practices, including regular brushing and flossing, can help prevent infections and promote healing. Use a soft toothbrush to avoid further irritation.

7. Hydration:
Staying well-hydrated can contribute to overall oral health and help prevent dry mouth, which may exacerbate mouth ulcers.

8. Stress Management:
Techniques for managing stress, such as relaxation exercises, meditation, or counseling, may be beneficial for individuals whose ulcers are stress-related.

9. Dietary Changes:
Modifying the diet to include more soft and bland foods during periods of ulceration can help minimize irritation.

Nutrients and supplements:
1. Pyralvex – for sore gums and mouth ulcers

2. Vitamin B Complex – B vitamins, including B12 (cobalamin), B6 (pyridoxine), and folate (B9), play a role in maintaining oral health. Deficiencies in these vitamins have been associated with an increased risk of mouth ulcers.

3. Iron – Iron deficiency anemia can contribute to the development of mouth ulcers. Iron supplements may be recommended for individuals with confirmed iron deficiency.

4. Zinc – is essential for wound healing and immune function. Some studies suggest that zinc supplements may help reduce the frequency and severity of mouth ulcers.

5. Buffered Vitamin C – While vitamin C deficiency is not a common cause of mouth ulcers, this vitamin is important for overall immune function and wound healing. Adequate vitamin C intake from a balanced diet is usually sufficient.

6. Vitamin D – is essential for immune function, and maintaining sufficient levels may contribute to overall oral health. Adequate exposure to sunlight and dietary sources may be enough for some individuals.


The exact cause of mouth ulcers is not always clear, but they can be triggered by factors such as:

1.Trauma or Injury: Minor injuries to the mouth, such as accidental bites, dental work, or irritation from braces or dentures, can lead to the formation of ulcers.

2. Stress: Emotional stress and anxiety can contribute to the development of mouth ulcers. Stress is believed to weaken the immune system, making the body more susceptible to various conditions, including oral ulcers.

3. Hormonal Changes: Hormonal fluctuations, particularly in women during menstruation, pregnancy, or menopause, may be associated with an increased likelihood of developing mouth ulcers.

4. Certain Foods: Some individuals may be sensitive or allergic to certain foods, such as acidic or spicy foods, chocolate, nuts, and citrus fruits, which can trigger the formation of ulcers.

5. Nutritional Deficiencies: Deficiencies in essential vitamins and minerals, such as vitamin B12, iron, folic acid, and zinc, can contribute to the development of mouth ulcers.

6. Immune System Disorders: Conditions that affect the immune system, such as autoimmune diseases (e.g., Behcet’s disease), can increase the risk of developing recurrent mouth ulcers.

7. Infections: Viral, bacterial, or fungal infections in the mouth can lead to the formation of ulcers. For example, the herpes simplex virus can cause cold sores, which are a type of mouth ulcer.

8. Genetics: There may be a genetic predisposition to developing mouth ulcers. Individuals with a family history of recurrent aphthous stomatitis (RAS) may be more prone to experiencing these ulcers.

9. Certain Medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), beta-blockers, and certain antibiotics, may contribute to the development of mouth ulcers as a side effect.

10. Underlying Medical Conditions: Chronic diseases, including inflammatory bowel diseases (e.g., Crohn’s disease), celiac disease, and HIV/AIDS, can be associated with an increased risk of mouth ulcers.

Underlying Emotions


Individuals with mouth ulcers may find relief and support healing by following a diet that minimizes irritation and provides essential nutrients for overall oral health. Here are some dietary recommendations for managing mouth ulcers:

1. Soft and Easy-to-Chew Foods:
Opt for soft and easily chewable foods to reduce irritation during eating. Examples include cooked vegetables, mashed potatoes, yogurt, smoothies, and well-cooked grains.

2. Bland Foods:
Choose bland and non-spicy foods to avoid irritating the sensitive areas of the mouth. Plain rice, pasta, and mild soups are good options.

3. Non-Acidic Fruits and Vegetables:
Include fruits and vegetables that are low in acidity to minimize discomfort. Bananas, applesauce, steamed carrots, and cooked spinach are examples of low-acid options.

4. Lean Proteins:
Include lean protein sources, such as poultry, fish, eggs, and legumes, to support tissue repair and overall health.

5. Dairy Products:
Dairy products like milk, yogurt, and cheese can be soothing and provide essential nutrients. Choose low-acid varieties.

6. Hydration:
Stay well-hydrated to support overall health and prevent dry mouth, which can exacerbate mouth ulcers. Water is the best choice, but other non-acidic beverages can also be consumed.

7. Avoid Trigger Foods:
Identify and avoid foods that may trigger or worsen mouth ulcers. This can include spicy foods, citrus fruits, tomatoes, chocolate, and nuts, among others. Individuals may have specific triggers, so it’s important to pay attention to personal reactions.

8. Vitamin and Mineral-Rich Foods:
Consume a well-balanced diet rich in vitamins and minerals. Incorporate foods high in B vitamins, iron, folate, and zinc, as deficiencies in these nutrients may contribute to mouth ulcers.

9. Limit Caffeine and Alcohol:
Caffeine and alcohol can be irritating, so it may be helpful to limit or avoid these substances during periods of mouth ulceration.

10. Gentle Oral Hygiene:
Practice gentle oral hygiene to avoid further irritation. Use a soft toothbrush and avoid abrasive toothpaste. Consider using a mild, alcohol-free mouthwash or a saltwater rinse.
