What are mouth ulcers or canker sores?
Mouth ulcers, also known as canker sores, are small, painful sores that develop inside the mouth. There are several causes of mouth ulcers, including:
Injury or Trauma to the Mouth
Mouth ulcers can often be traced back to physical injury or trauma within the oral cavity. This type of injury can occur in various ways.
For instance, accidentally biting the inside of the cheek can cause a small wound that develops into an ulcer.
Similarly, using a toothbrush with stiff bristles or brushing too vigorously can damage the mouth’s delicate mucosal lining, leading to ulcer formation.
Another common cause is using ill-fitting dental appliances like braces or dentures. If they aren’t properly adjusted, these appliances can rub against the gums or inner cheeks, causing friction and sores.
Infection or Inflammation
Infections and inflammatory conditions can also cause mouth ulcers.
Viral infections such as herpes simplex can cause a specific type of ulcer, commonly known as cold sores, typically appearing on the lips.
However, other parts of the mouth can also be affected. Thrush, a fungal infection caused by Candida yeast, can also lead to painful mouth ulcers.
Beyond infections, systemic inflammatory conditions like Crohn’s disease, ulcerative colitis, or celiac disease can contribute to mouth ulcer formation.
These conditions often cause widespread inflammation in the body, which can manifest in the mouth.
Nutritional Deficiencies
Mouth health is closely linked to overall nutritional status.
Deficiencies in key nutrients can increase the risk of mouth ulcers. Vitamin B12 deficiency is a common culprit. This vitamin is vital for healthy red blood cell formation and proper nervous system function, and its deficiency can cause oral mucosal changes.
Similarly, iron deficiency, which can lead to anemia, can also cause mouth ulcers.
Folic acid, another essential nutrient, supports cell growth and division; a deficiency can cause similar effects.
Hormonal Changes
Hormonal fluctuations are another factor that can contribute to the development of mouth ulcers, particularly in women.
It is not uncommon for women to experience an increase in mouth ulcers during certain phases of their menstrual cycle, especially just before menstruation. This pattern suggests a link between hormonal changes and the onset of these ulcers.
Pregnancy and menopause, other periods of significant hormonal change, can also see an increased occurrence of mouth ulcers, although the underlying mechanisms are not fully understood.

Stress & Anxiety
Stress significantly impacts the occurrence and severity of mouth ulcers and canker sores.
Under stress, the body’s immune response can weaken, reducing its ability to fight harmful bacteria and viruses in the mouth. This weakened immune state makes ulcers easier to form and can worsen existing ones.
Additionally, stress and anxiety often lead to changes in oral hygiene habits and dietary choices.
Poor oral hygiene can increase the risk of mouth ulcers.
At the same time, a stress-induced diet, often rich in sugary, acidic, or spicy foods, can irritate the mouth’s lining, further triggering or worsening ulcers.
Moreover, stress-related hormonal changes and reduced saliva production, both crucial for oral health, can also contribute to these painful sores.
Managing stress through relaxation techniques, a balanced diet, and good oral hygiene practices is essential in reducing the frequency and severity of mouth ulcers and canker sores.

How do you treat mouth ulcers/canker sores?
Treatment for mouth ulcers usually focuses on relieving the pain and discomfort and promoting healing. Some treatment options include:
Over-the-Counter Pain Relievers
Over-the-counter (OTC) pain relievers can provide immediate relief from the discomfort caused by mouth ulcers.
Medications may reduce pain and inflammation associated with mouth ulcers. Medications generally work by inhibiting the production of certain substances that cause pain and inflammation.
Follow the recommended dosage and watch for potential side effects, especially if you take other medications or have existing health concerns.
Topical Treatments
Topical treatments are directly applied to the ulcer and can provide targeted relief.
Over-the-counter creams or gels that contain benzocaine, lidocaine, or hydrogen peroxide can be particularly effective.
Benzocaine and lidocaine are local anesthetics that numb the area, providing temporary pain relief.
Hydrogen peroxide, on the other hand, is a mild antiseptic that can help clean the area and promote healing.
Apply these treatments with a clean finger or cotton swab. Use these products as directed to avoid irritation or allergic reactions.
Mouthwash Solutions
A mouthwash solution can also help heal mouth ulcers.
Rinsing with a saline solution, made by mixing a teaspoon of salt in warm water, can help to reduce inflammation and keep the area clean.
Another option is a baking soda rinse, prepared by dissolving a teaspoon of baking soda in water. This can help neutralise acids in the mouth, reduce irritation, and promote healing.
You can use these rinses several times daily, but do not swallow them.
Dietary Adjustments
The foods and drinks you consume can significantly affect mouth ulcers.
Spicy, acidic, or rough-textured foods can irritate ulcers, making them more painful and potentially slowing healing.
To minimise discomfort and support healing, avoid these irritants.
Opt for soft, bland foods and avoid acidic fruits, spicy dishes, and crunchy or hard snacks.
Drinking plenty of water also helps keep the mouth clean and can support healing.
Summary
Mouth ulcers and canker sores are common oral conditions that can cause significant discomfort but are generally not a cause for serious concern.
Understanding their potential triggers, such as stress, nutritional deficiencies, hormonal changes, and physical trauma, is key to both prevention and management.
While these sores heal on their own, good oral hygiene and a healthy lifestyle can speed recovery and reduce recurrence.
If you experience frequent, severe, or unusually persistent mouth ulcers, seek medical advice, as they can sometimes signal an underlying health issue.
Effective management and prevention of mouth ulcers and canker sores contribute significantly to oral health and comfort.
